Mini Cooper S owners have reported 49 problems linked to timing tensioner (under the engine and engine cooling category).
#1 - Timing Tensioner problem of the 2008 Mini Cooper S
The car involved was a 2008 Mini Cooper S. Timing chain mechanism (tensioner seemed to be main culprit) failing and system needed replacement. Total cost $2500. Car had 33,000 easy miles on it. Mechanic said timing system was on the verge of failing traumatically and destroying the engine. Reported it to Mini, who admitted they have been having a lot of trouble with those but there had been no recall so they couldn't help me. Replacement parts were different serial numbers than the originals indicating, per my mechanic, they had redesigned the parts. It was Sep. 3, 2013 when this timing tensioner issue occurred.

#2 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle involved was a 2008 Mini Cooper S. The vehicle's vehicle identification number (VIN) is WMWMF73538_. Engine rattle on cold start indicated a loose or stretched timing chain. Required a premature replacement of timing chain, guides and tensioner. This problem occurred on Friday, February 15, 2013.
#3 - Timing Tensioner problem of the 2010 Mini Cooper S
The vehicle involved is a 2010 Mini Cooper S. The VIN of this Cooper S is WMWMF7C57A_. Engine experience rapid oil loss which coated underside of vehicle including tires. When the brakes were applied the vehicle became unstable but I was able to avoid a crash. While pulling to the side of the highway the oil light came on. The vehicle was towed to a mechanic. He reported that a fastener on the cam chain tensioner had become loose which caused the leak. That part had never been modified or service. There was no leak when I began my commute. The problem occurred in only a few miles. Searching online forums indicates that this is not an isolated incident. This timing tensioner problem happened on 09/09/2013.

#4 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle having this issue was a 2007 Mini Cooper S. The VIN of the car is WMWMF73527_. This vehicle has twice had a failure of the timing chain as a result of a faulty tensioner, resulting in catastrophic engine failure. The first incident occurred from a dead stop in a parking lot so there was no immediate safety issue. The second incident, occurring 12/03/2012, manifested as the vehicle was DE-accelerating coming off a highway exit with a total loss of power at the bottom of the exit, in a remote area. Mini Cooper Sent their technicians in 2007 a "service bulletin," short of a recall, when the trend was discovered among its "r56' model engines in 2008. I had warned Mini of sounds which later were determined by independent experts to be the timing chain's "death rattle" prior to the first failure, which they attributed to the car's "go-kart like start up. " after 6 months of struggling, Mini agreed to 80% of the repair costs, with a new timing chain under a one year warranty. Other failures sidelined the vehicle for months in the intervening time, and due to the incredible cost of repair the vehicle had to be garaged until repaired. So although over a year passed between timing chain failures, about only about 39k miles were driven in that time. As of now, Mini is only offering 50% culpability, this after starting a vocal twitter campaign. I still owe $10k on a vehicle that requires up to $5k in repairs- a repair which will only replace a defective part with the same defective part. This issue happened on Apr. 20, 2010.

#5 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle was a 2008 Mini Cooper S. While driving the car (gas) started running rough and sounded like it was a diesel. After some research I found that the tensioners in the engine are worn out. I had the upper replaced, but the others also need replacing. Based on my own research, it appears the problem is related to the manufacturer's recommended oil change. The company recommends changing oil every 15000 miles with syntetic oil. The fix is supposedly to change the oil at half that, 7500. I've been told this could result in the timing chain coming off and the engine being trashed. It was Thursday, March 28, 2013 when this timing tensioner issue occurred.
#6 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle involved is a 2007 Mini Cooper S. The vehicle identification number (VIN) is WMWMF73557_. With only 23,000 miles, engine exibited a loud rattling noise at idle, and running up to about 2800 rpm, when noise would disappear. Took it immediately to dealer, who diagnosed it as a failure of the timing chain tensioner piston; that failure caused the chain to skip and throw the cam timing out of alignment, according to the dealer. . . Cost of $188. 00 to replace timing chain tensioner, and $471 to diagnose cam timing skip and restore cam timing. . . Total cost $659. Dealer refused to submit claim to Mini north America for goodwill coverage, despite outstanding condition, low mileage, regular dealer maintenance, and proper oil levels and change intervals. This issue with the timing chain tensioner failure and resulting damage is well known and well documented and should be the subject of a recall and repair of entire timing chain system at Mini's cost-- severe cases can result in catastrophic engine failure at highway speed and potential crashes/fatalitites. Nhtsa, please make Mini do the right thing!!!!. It was 05/16/13 when this timing tensioner issue happened.
#7 - Timing Tensioner problem of the 2007 Mini Cooper S
The car involved is a 2007 Mini Cooper S. The vehicle's vehicle identification number (VIN) is WMWMF73527_. I have been experiencing a major flaw with oil supply/return lines to the turbo. A condition exists where if left unattended and uncared for creates the high risk of fire and subsequent loss of engine/vehicle. This event can happen at any time the car is being driven and/or later parked. The risk is created when oil accumulates, either through time or over a leisure drive, and collects near/on the exhaust manifold & turbo components, both of which operate at extremely high temperatures. It is becoming a daily task to look under the car hood and investigate for accumulation of oil near these parts due to the fact that the car smells of burning petroleum. Need I be more apparent of burning oil that will burn and destroy a car due to a faulty product? this has been occurring for the majority life of the car but he issue has never been professionally addressed due to disregard of the Mini/BMW dealerships to accept this design flaw. If researched further, there are many standard examples of this design flaw and numerous descriptions, images, examples, forums, and complaints of this flaw occurring in many cars of various styles, mileage, and trims occurring within the same year model of 2007. I have also experience many of the major flaws already listed and complained about on the nhsta such as the ¿death rattle¿ belt tensioner failing (luckily no catastrophic engine failure and which has been listed numerous times on nhsta, numerous), valve cover replacement (also listed), etc. Nhsta, address this problem as it is an avid and dangerous safety issue. The common person does not check under the hood daily and its only time before someone parks their Mini in a garage and the home goes down in flames. I personally don¿t park the Mini in the garage for fear of fire. Do not repair the Mini with the same faulty oil line design. Recall design. The failure date was May. 8, 2013.
#8 - Timing Tensioner problem of the 2009 Mini Cooper S
The car involved was a 2009 Mini Cooper S. The vehicle's vehicle identification number (VIN) was WMWMF73529_. Mini released a service bulletin (campaign: sim 11 02 12) regarding faulty timing chain tensioner. At appx. 40k miles, my Cooper S was taken in for service and it was reported there was a "rattle" in the front of the engine. The dealership replaced the tensioner under warranty. Now the same issue has occurred. I am being told the entire timing chain assembly needs replacement at an approximate cost of $3k. Mini has offered to pay 1/2 the cost. There is no explanation why the repair is not covered under 2 year replacement tensioner warranty; since this original issue was only partly addressed while in 50k car warranty. My Mini now has 77k. Once warranty request is submitted from dealer to Mini corporate, decision is final. There is no appeal. Failure to perform service will result in engine failure in near future. This timing tensioner issue occurred Thursday, Mar. 14, 2013.

#9 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle is a 2008 Mini Cooper S. Strange knocking/rubbing noise coming from the engine compartment for the year 2007+ Mini cooper. From the Mini dealer repair details it appears to be a issue with the timing chain and tensioner system. It also appears that without being fixed the car will eventually have a timing chain failure and possible motor destruction. This could occur while driving and I could lose control of the vehicle causing a crash. Mini will not fix this problem that they know about without the vehicle still being under warranty. I call for a recall. This problem occurred on 02/28/12.
#10 - Timing Tensioner problem of the 2008 Mini Cooper S
The car involved was a 2008 Mini Cooper S. The timing chain tensioner backed out of the engine block allowing engine oil to be pumped out of the engine. The tensioner works on engine oil pressure and it backed out far enough to allow the engine oil that normally pressurized the piston to be pumped out of the engine. I was lucky enough to see the streak of oil as I backed out of the driveway, but if I had not I am sure that more damage and potential fire would have occurred. This is surprising as this same part was replaced under a recall for being faulty. I believe that this is still a design flaw and something that should be addressed by Mini. It was Jan. 21, 2013 when this timing tensioner issue occurred.
#11 - Timing Tensioner problem of the 2009 Mini Cooper S
The vehicle involved is a 2009 Mini Cooper S. Vehicle was taken to dealership in Feb 2012 for a rattling noise. Service center at braman miami said that they could not duplicate the noise, so it was assumed they found nothing wrong with the vehicle. Prior to this, the vehicle had been in the shop 2-3 times due engine malfunction light, rough idle at cold start and loss of turbo power due to leakage in turbo oil feed lines. This was repaired in early 2012/late 2011. In December of 2012, while driving the rattling noise of the complaint in Feb 2012 intensified and oil light illuminated while driving. Car was pulled over to safe location. Once car was stopped, the engine malfunction light also illuminated. Driver checked oil level, which appeared low but within the marks on the dipstick. Oil splatter was observed on the hood and on engine. Rubber gasket feeding to engine was observed to be displaced where oil appeared to have leaked out. Vehicle was towed to braman miami. Service department reported that failure was caused by timing chain/tensioner issue. Service dept is charging 17k usd for repairs as it is not found to be under the scope of warranty of previous repairs to the turbo oil feed lines. Mini has been contacted to see if any relief can be provided as this seems to be a common issue with these vehicles. This timing tensioner problem happened on 12/23/12.
#12 - Timing Tensioner problem of the 2009 Mini Cooper S
The car involved is a 2009 Mini Cooper S. Driving vehicle heard some engine noise and observed red oil indicator came on. Pulled over and checked oil level, appeared to be low. . I immediately put in two quarts of oil only to see it all seep out and through both front wheel wells. Appeared to be an issue with the timing chain tensioner. This problem occurred on Nov. 5, 2012.
#13 - Timing Tensioner problem of the 2007 Mini Cooper S
I own a 2007 Mini Cooper S, that I purchased brand new in June of 2007. I immediately fell in love with the car and knew that this would be the last car I would ever own. It is a $31,000 car that I have blood, sweat, and tears made expensive ($560/month) payments on for the last five years. About two years into owning this car, I noticed when it was cold out that my Mini would get what is now known as "the death rattle". When I called ralph schomp Mini (where I had purchased it), they told me that the noise was nothing that I had to worry about and that it just had to do with cold weather. A year after that my Mini would struggle to get moving, I thought it was a battery problem, again the mechanics at ralph schomp Mini told me not to worry about it, again just cold weather. A couple weeks ago, I noticed that my car was acting up severely. The check engine light came on. Then a couple days later it went off and it seemingly stopped having issues. About a week after that, it started acting up again and the check engine light came back on. I attempted to take it to another auto place to have it diagnosed, but it was non-conclusive, and the symptoms only got worse. I had my Mini towed back to ralph schomp Mini, and their diagnosis resulted in saying that the timing chain tensioner malfunctioned and had come loose which did significant damage to the engine and that I would need to replace the engine. An engine supposedly built to last at least to 250,000 miles only made it until 52,000 miles and will cost me as much as $8,000 to repair. My warranty expired literally six months ago, and I am only about three months away from having her paid off. In looking up this issue online, many other 2007 Mini owners have also had this issue. I am incredibly disappointed in the entire situation, and would encourage a recall to be issued on 2007 Mini Cooper S. This issue happened on Saturday, Nov. 3, 2012.
#14 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle was a 2008 Mini Cooper S. Began to hear loud knocking noise from engine of my 4 year old Mini @ 66000 miles. Have had my Mini serviced according to the schedule at the same dealership for 4 years. After hearing the noise did research online to notice that Minis have a timing belt /tensioner issue. Noticed on the same night that my oil light came on and the interesting thing is that I just had my oil changed in August of 2012 and this was November 2012. Took car to dealer and the servicer said they had heard of some Mini's timing chains failing at 14k miles. After diagnosis he notes that it is the timing chain and that the oil filter gasket was leaking which caused the timing chain to fail. This is not correct as my vehicle has never leaked oil, and I had just gotten my oil changed 3 months earlier and no mention was made by my service technician. This seems to be a common issue in Minis and they are not providing any kind of relief. It was Saturday, Nov. 17, 2012 when this timing tensioner issue happened.
#15 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle involved is a 2007 Mini Cooper S. Was driving back from vacation, and upon getting off the highway we had noticed a loud rattling was coming from the engine. Brought the car to a mechanic who said the timing chain tensioner had failed, resulting in the timing chain to be loose and destroy the rails it rode on. Upon looking into this issue further, discovered there is a TSB out about this issue, and many owners have had this same problem, but it is not a recall yet. It was Monday, October 15, 2012 when this timing tensioner issue happened.
#16 - Timing Tensioner problem of the 2009 Mini Cooper S
The timing tensioner on my Mini Cooper S backed out, resulting in a massive oil loss while at highway speeds. This is apparently a known issue by Mini, but no known recall has been issued at this point. It was 09/29/12 when this timing tensioner issue occurred.
#17 - Timing Tensioner problem of the 2007 Mini Cooper S
The car involved is a 2007 Mini Cooper S. Engine timing chain tensioner malfunctioning causing decreased accelerating power and a loud rubbing/knocking noise when driving, that will cause engine damage if not promptly fixed. It is a well know Mini cooper problem (2007 models to current year) and the Mini dealership I took mine to has had many complaints about the issue. Mini has came out with replacement parts and a service guide on how to repair the issue at a hefty cost (if the engine hasn't already been damaged); however, Mini/bwm has not issued a recall or replacement at no cost to consumers to back up their product. Estimates for repair in my area were $1300-$1600 if repairable because again, it will cause engine failure if not fixed quickly. My car has 41,000 and have had my Mini serviced at the designated time intervals at only Mini services areas. Such a major repair that could have eventually caused my engine to stop working should not happen at 41,000 miles. Mini/bwm should back up there product with repairs and needs to find an ultimate fix because it is an issue even in the current models. This problem occurred on Thursday, August 23, 2012.
#18 - Timing Tensioner problem of the 2007 Mini Cooper S
The car involved was a 2007 Mini Cooper S. The vehicle's vehicle identification number (VIN) was WMWMF73527_. Timing chain tensioner replaced July of 2011 now aug31,2012 loud noise timing chain stretched so replaced & tensioner replaced again. This timing tensioner problem happened on 07/21/11.
#19 - Timing Tensioner problem of the 2007 Mini Cooper S
The car was a 2007 Mini Cooper S. In January 2012 with 37,000 miles on it my Mini started having very noisy starts. The noise would go away after it warmed up. Took the vehicle to Mini dealer and they said that it was the timing chain and tensioner. They agreed to replace the timing chain, tensioner guides etc for half price as a good will gesture. Now I find out that this is a common problem. This issue happened on 01/06/2012.
#20 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle is a 2008 Mini Cooper S. Knocking noise when starting and running. I thought it was from the wrong fuel added to it, or low oil when I purchased it. I corrected those two issues, but it still makes the knocking noise. I am very afraid it will seize. I believe the timing chain and tensioner system needs to be replaced. It was 08/20/12 when this timing tensioner issue occurred.
#21 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle having this issue was a 2007 Mini Cooper S. Timing chain and tensioner failure mentioned by others also occurred in my car. Failure in my case was progressive: started with rough starts, noisy idle (from chain impacting cover!) progressed to non-existent acceleration above 4000 rpms (a safety issue on the highway) . Brought the car to mechanic and while he was investigating the obvious air leak, car failed to start. Dealer eventually discovered bent valves from impact with piston preventing proper seal, but only after replacing snapped tensioner guides and timing chain dropped into oil pan for $2,525. Had this occurred while driving it poses a significant safety issue. Then they tell me they can replace all valves for $4,500. Total cost, over $7,000. Effectively, this is a total engine failure and it would be cheaper to drop in a complete new engine. Mini and their dealers are well aware of this problem and as it can - and has - resulted in failures for other motorists at highway speeds it poses significant safety risk and should be addressed with a recall. This problem occurred on July 23, 2012.
#22 - Timing Tensioner problem of the 2007 Mini Cooper S
The car involved was a 2007 Mini Cooper S. VIN of the vehicle was WMWMF73597_. Engine is rattling horribly. In doing some research it sounds like what most are calling the "rattle of death". The timing chain is making entirely too much noise. And car is running poorly. I can not and will not drive this car till it is repaired! this is a potential catastrophic engine failure. Mini cooper knows about this major engineering problem and will not issue a recall. Repair estimates are as much as $2500. 00 for timing chain and timing chain tensioner. It was Sunday, Aug. 5, 2012 when this timing tensioner issue happened.
#23 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle involved is a 2007 Mini Cooper S. The VIN of the car is WMWMF73547_. Mini cooper drivers around the u. S. And world have been reporting a strange knocking/rubbing noise coming from the engine compartment for the year 2007+ Mini cooper. From the misc dealer repair details it appears to be a issue with the timing chain and tensioner system. It also appears the without being fixed the car will eventually have a timing chain failure and possible motor destruction. On a good note BMW/Mini know what the problem is however is failing to come up with or acknowledge a permanent solution. How many customers issues will it take before BMW/Mini will issue a full recall?. This timing tensioner problem happened on Monday, July 16, 2012.
#24 - Timing Tensioner problem of the 2008 Mini Cooper S
Vehicle identification number (VIN): WMWMF735X8_. My Mini Cooper S has less than 60000 miles on it with proper maintenance and has had failure of the friction wheel (aka timing chain or tensioner system). The first signs of the issue are a very loud, rattling noise during acceleration and as the problem gets worse, it continues to rattle during idling. The Mini corporation is very aware of this problem and while the dealership itself worked with me to lower the cost because they say it happens frequently even with proper maintenance on the car and while the vehicle is still under warranty, the corporation wouldn't acknowledge or help with the cost to fix it. Also, if the problem isn't fixed immediately, it will lead to a blown engine. Furthermore, I have read that several Mini owners have replaced the friction wheel only to have the same problem reappear not long afterwards. This is an issue of faulty manufacturing and Mini needs to stand up and absorb the cost to fix it and/or recall the Minis affected to ensure it no longer happens. This problem occurred on April 2, 2012.
#25 - Timing Tensioner problem of the 2007 Mini Cooper S
The owner has a 2007 Mini Cooper S. While driving approximately 45 mph, the engine warning indicator began to illuminate as a loud rattling noise emitting from the engine area. The vehicle suddenly stalled and failed to restart. The vehicle was towed to a dealer who was unable to duplicate the problem or determine the cause of failure. The malfunction continued to occur. Most recently the vehicle was taken to an independent auto shop and they stated the engine timing tensioner and the high pressure fuel pump would need to be replaced. The technician advised the vehicle be taken to a dealer for repair. The vehicle had not been repaired. The manufacturer was notified of the defect. The approximate failure mileage was 36,000. The VIN was unavailable. It was June 10, 2008 when this timing tensioner issue occurred.
#26 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle having this issue was a 2007 Mini Cooper S. The VIN of this Cooper S is WMWMF73507_. Mini issued a service bulletin on failed timing chain tensioners in 2009. Service bulletins sim-11-02-07 and puma measure number 10686850-13. The bulletin states that when a customer comes in with a tensioner problem that all cars affected will receive a new timing chain, chain guides, cam sprockets and vanos unit. On 6/23/10 my vehicle required this repair. Because I wasn't aware of the service bulletins the Mini dealership only replaced my vehicles tensioner without replacing the other parts. . . The tensioner is an easy replace and the actual timing chain is a 9. 9 hour job so I'm assuming they took the easy route with less accumulating labor. Now we're 23 months into that repair and the timing chain tensioner has gone bad. . . Again. This time the tensioner going out also caused the timing chain to fail along with the chain guides. Mini will replace the tensioner again, which is a 26 dollar part, because it is within the 24 month warranty. . . But because the Mini dealer that last replaced the tensioner did not follow the bulletins issued and replace the other pieces involved in the bulletin, they say I'm responsible. Mini now wants to charge me 1967 dollars for the repair of the timing chain and chain guides because it says the other parts are not covered. The car has 50,062 miles (warranty is to 50k). There are well over 200 entries that I found on the internet with this problem and a petition with over 650 signatures. When is something going to be done?. The failure date was June 23, 2010.
#27 - Timing Tensioner problem of the 2007 Mini Cooper S
The vehicle was a 2007 Mini Cooper S. The vehicle identification number (VIN) is WMWMF73567_. Eight months after Mini of concord replaced my high pressure fuel pump for the gasoline leak and strong gas smell within the cabin, again the gas smell started up in the cabin (for all trips). I took it back to Mini of concord (this is 22 months after buying car), and they again found a leak in the high pressure fuel pump and line, and replaced the parts - again. This was the fourth replacement of the high pressure fuel pump on my car! they also replaced the timing chain tensioner because of the loud noise it was making on startup. And the inlet camshaft position sensor. This timing tensioner problem happened on Jun. 9, 2009.
#28 - Timing Tensioner problem of the 2007 Mini Cooper S
The car is a 2007 Mini Cooper S. The vehicle identification number (VIN) of this Mini Cooper S is WMWMF73527_. Took my car into the Mini dealer today due to the fact that it was idling low, sounded like a diesel when it turned on and made a knocking noise. Mini let me know that it was in fact my timing chain and tensioner system that was making this sound and needed to be replaced. If it had not been replaced, I could have experienced complete engine failure. My Mini is not the only one that has had this problem, therefore I feel like Mini should cover the cost of fixing my timing chain and tensioner since it is going to cost me approximately $2,500 to fix it. I guess I should be thankfully that I was able to get my Mini to the dealer before it suffered a complete engine failure. This problem occurred on June 15, 2012.
#29 - Timing Tensioner problem of the 2007 Mini Cooper S
The car involved is a 2007 Mini Cooper S. The timing chain tensioner brackets all broke on my 07 Mini. My mechanic stated that this in not a new issue and the it is a frequent problem that he deals with on several Minis. They are made of plastic and when cracked or broken they allow my timing chain to slip causing damage to my engine. I have already spent over 2000 dollars in repairs for this problem, and it has happened twice in the last 5 year that I have owned the vehicle. BMW/Mini must take responsibility for their defective engine parts. There should be a recall on these vehicles for it can cause enough damage to were you would need a new engine. This problem occurred on Jul. 2, 2010.
#30 - Timing Tensioner problem of the 2009 Mini Cooper S
The vehicle was a 2009 Mini Cooper S. The vehicle identification number (VIN) is WMWMF735X9_. My vehicle had been parked for a couple of days in our garage. When I pulled it out on the 2nd I noticed a large pool of oil on the floor. I immediately drove it to the local dealership and was informed that the timing chain tensioner system had failed and that if not immediately remedied this would cause catastrophic engine failure. Over my communications with the dealer, Mini of sterling in sterling, va, I was told that this was a frequent occurrence, at least one a week, and is a recognized problem with a known work-around. They informed me that they had seen catastrophic engine failure and that with my commute of 45 miles on major highways that such a failure at speed would result in a major crash. This timing tensioner issue occurred Wednesday, February 2, 2011.
#31 - Timing Tensioner problem of the 2009 Mini Cooper S
The car is a 2009 Mini Cooper S. Why is my VIN # not added to this recall? it has all the same symptoms. . I called Mini USA without getting anywhere. Did I just a buy a lemon? see info below: the cold start issue has been a common theme popping up in the faults and fixes threads on various Mini forums. Specifically, mcs owners complaining about a peculiarly loud engine rattle on start-up. Now the r56 is a n?interesting" sounding engine to begin with. The direct fuel injection solenoids give the car a very diesel-esque sound at idle. But this is a very different sound altogether. BMW has determined that the cold start rattle was/is being caused by the timing chain tensioner (which is in turn powered by an oil-pressurized piston). More specifically the sound is caused when the tensioner piston doesn't extend all the way (or at all) which then allows the timing chain to come in contact with the guides on the engine cover. After two years of research into the issue Mini now has official repair information at dealers that will eliminate the issue. The puma measure number that will need to be referenced is 10686850-13 (we've seen 10686850-12 mentioned but we believe 13 is the latest) and the part number is 11. 31. 7. 598. 956. According to the information we've seen, all cars affected in with the issue will get a new timing chain, chain guides, cam sprockets and vanos unit. At this stage Mini is handling this on a case by case basis when the owner complains about the sound. Were guessing they would like to steer clear of something along the lines of a recall (voluntary or otherwise) due to the cost of the service. However don't be surprised to see and hear more about this issue and the official fix soon. In the mean time if your 2007-2009 mcs is affected wed urge you to call and make an appointment at your local dealer. This issue happened on 12/29/11.
#32 - Timing Tensioner problem of the 2009 Mini Cooper S
The car involved is a 2009 Mini Cooper S. While driving vehicle, oil started to drain in large quantities over the street. Steady stream about 2 inches wide was visible on the street once vehicle was stopped. Oil light came one approximately 5 minutes after oil spin was noted. Car was moved to safe location once oil light came on. Engine would not restart. Notes from knauz Mini service manager: found timing chain tensioner walking out of position causing oil to come out of cylinder head. Cleaned oil residue and replaced timing chain tensioners. Due to lack of proper tension of timing chain tensioner checked timing. It was Apr. 23, 2011 when this timing tensioner issue happened.
#33 - Timing Tensioner problem of the 2008 Mini Cooper S
The vehicle was a 2008 Mini Cooper S. Noticed a strange sound, almost like wheel bearings were grinding. On November 11, 2010, when starting the vehicle, check engine light came on, and engine did not seem to have as much power as it should. Took to the Mini dealership and they said the engine light was on because the turbo was damaged. Apparently the oil supply hose to the turbo was either blocked or cut, and was not providing oil to the turbo. As a result of the lack of oil, the bearings in the turbo were ruined. Had to replace the entire turbo. After the turbo was replaced we were told the timing chain was going bad. Was told the timing chain, tensioners, and guides needed to be replaced. I've read where the timing chain has been a continuing problem with Mini coopers, and that, if fixed, it will go bad again and could cause a severe engine problem, resulting in failure. I also wonder if the timing chain is already damaged enough to cause the oil supply hose to the turbo to be damaged. The failure date was Thu., Nov. 11, 2010.
