Mini Cooper S owners have reported 34 problems related to engine oil leaking (under the engine and engine cooling category).
Turbo leaking oil - gaskets - major complaints all over the internet. Maybe this is something they need to review for design error.

The turbo oil feed line is leaking. It is a know issue with these vehicles, it can result in a fire as the oil sprays our the lines on the exhaust. Dealer has to comment about the repairs being free of charge but does say it's a known issue. Many Mini coopers have caught on fire because of this issue.

The turbo oil feed line is inherently flawed and prematurely fails because of a bad design. This failure causes hot oil to leak all over a hot turbo. I was lucky enough to not have my engine catch fire with the failed o-ring on mine. I was driving on the highway when large clouds of smoke begin to flow from the engine compartment. I was forced to pull over and get towed home. I was out of warranty but still very low mileage (48k) when mine failed.

Fuel smell started to get stronger in the cabin and outside of the vehicle, but did not see any leaks on the floor till today. I also notice the green temperature notification come on today. I had my oil changed at the BMW/Mini dealer in ontario last month.

Purchased at 61,000 miles 9/9/14; had synthetic oil change 5/15; 9/29/15 car began to have a rattle but unsure if it was front of car or back of car. Rattling stopped on acceleration. No warning lights came on. 10/4/15 car died at 69,362 miles while driving on a two lane road on a curve. Was able to coast to getting half the car off the road. Bypassers pushed me off the rest of the way. Towed to mechanic who said it was the timing chain guard that split off. Called Mini they said their dealership service dept had to look at it. Had it towed to OH 70 miles away. They told me I had an oil leak which caused the following to be damaged - crank shaft, harmonic balancer, cylinder head, timing chain and guard and maybe other stuff but they couldn't tell without further examination. Told $5,000 plus to fix, but I see Mini estimate states $3,500-4,500. My local mechanic found no evidence of an oil leak causing the trouble, nor did I have an oil spot where I parked my car in the garage or work parking lot. No oil or engine light came on.
The turbo oil feed line is a known failure point on the engines put in this generation of Mini Cooper S models. The oil line uses a "o" ring gasket behind a pinch/crimp connection. This connection is directly in contact with the hot side of the turbo and fails due to excessive heat. This allows engine oil to leak out over the turbo and down the front of the engine. This could cause the engine to run low on oil at best. At the worst it could cause a fire if the turbo gets hot enough to ignite the oil that is leaking out.
Turbocharger oil feed line leaking. The part is poorly designed and according to the research I've done prone to failure. The dealer wants $1200 to replace it. When I questioned the service person about the heat shield recall from just last year to prevent this issue from occuring, he reassured me that the heat shield recall was because of the number of paint jobs they had to do on hoods from the heat off the turbo damaging the hood paint. I think Mini should cover the cost of replacing the oil supply line since they are well aware that this part is faulty, it gets too hot and leaks. The heat shield recall doesn't stop the damage already done. It seems my 2008 Mini is not immune to any of the "known" issues this car has. Everytime I visit the Mini dealership it's another well known issue/repair. While the dealership was very helpful with the last issue (timing chain), they were not with this latest one. They said because it was out of warranty there was nothing they could do.
The dealer informed me my oil feed lines to the turbo were leaking and would need to be replaced soon. After doing some research found the couplings that attaches these lines to the turbo are defective. The dealer says there is not a recall and will cost approx: $1200. 00. The dealer installed a turbo shild to help with the heat that is casuing the line to prematurely fail. With so many effectived shouldn't Mini be fixing this issue.
Leaking turbo oil feed line and failing timing chain.
Upon th eengine heating and cooling the plastic gasket on th eengine oil cooler can get pinched, causing an oil leak. Mini coopers in prior years - 2002-2007 had the same issue and Mini had a recall. If I spend the $1,800 to get the repair the next time the engine heats up and cools - the gasket could become pinched again - thus causing a leak. Mini cooper of atlanta is yes this could happen and I would have to get it repaired again. Mini cooper needs to ensure the 2 plates of the metal oil cooler are secure and cannot expand and shrink - upon engine usage. This is the same manufacturing flaw Mini cooper had in 2002 - 2007 - so why hasn't Mini cooper been told to fix their problem - verses throwing the responsibility to the customer?.
As I was driving the car, the hood in the front started to release smoke. There was also a smoking smell. This continued throughout the ride. Brought the car to a mechanic who indicates that the car is leaking oil onto the engine, making it extremely dangerous to drive as it can cause a fire. This problem continues to exist after I replace the oil pipe.
Turbo oil feed line leak, oil filter housing gasket which is costing me close to 1200$.
Rattle and oil leak. Loss of full engine power when restarted. Dealer says its a timing chain assembly issue.
Fire did not occur, but there is a risk. Many Mini cooper models with turbochargers are experiencing a leaky oil feed line to the turbo after approximately 25,000 miles. Due to a poorly insulated rubber gasket. It is a manufacturing flaw, but Mini has failed to acknowledge the issue. This is a fire risk. The oil is allowed to leak into the engine bay, and it can destroy the engine because Mini coopers do not have an oil sensor.
Turbocharger oil feed line leaking. The part is poorly designed and according to the research I've done prone to failure. The part is not covered by the cpo warranty and the dealer wanted $1400 to replace it. I replaced it myself with a better designed aftermarket part. I think Mini should cover the cost of replacing the part with a better design.
It has oil leaks around turbo line which the oils make smokes as the oil drip contacts with down pipe. This may result in serious damage to the car.
Fuel leak a/p Mini service; not covered by extended warranty; after extensive research advised service representative of the reported design flaw in crimp device holding oil line connecting to turbo. Advised by independent mechanic turbo unit defective, needs replacement. Mini of fairfield returned vehicle in an unsafe manner with stripped bolts and improper placement of oil pan. After calling BMW of north America Mini of fairfield decided to change oil lines without changing turbo unit. On driving vehicle noticed smoke coming from hood; vehicle revving in park, and a metallic sound coming from under vehicle; returned to Mini service and after further evaluation (diagnostic fee $100)I was advised that car is safe to drive; I tried 2 different Mini service departments neither would replace turbo unit considering the fire hazard as reported.
I purchased a Mini Cooper S 2013 and noticed the car was hard to handle on the road at all times. The service department had told me that was normal for this type of car. I kept complaining and they finally took the car in to have it checked. They told me it the alignment was bad and the tires needed to be replaced. I was charged for the service, but I believe this was a manufacture defect because the car was like that from the time I drove it off the lot until the time of service. This, is a very serious matter if not only one car is sold like this. Not to mention the whole engine was leaking oil and the backfiring .

Engine bay started smoking. Pulled the car over and notice the turbo oil line was leaking hot oil everywhere. Could of resulted in a engine bay fire.
Third complaint and counting. . . . . I went to start my Mini, only to notice it was leaking oil heavily under my car. I brought it to my repair shop who told me it might be the o ring. They replaced it and told me to bring it back a week later. I returned Friday July 19th to have them look under the hood. There was oil everywhere. All over the engine. The seal was fine! it turns out the vacuum pump needs to be replaced and possibly the timing chain at a later date. The cost for the pump and labor is $574. 00. So far I have spent almost $4000. 00 on repairs. I don't have an estimate for the timing chain, I can only imagine. I only bought my Mini in February at 49k miles and she's been in the shop longer than she's been driven. I don't know what to do any more and wish that BMW/Mini would acknowledge that all r56 engines are defective. If I known I would have bought another better reliable car than a Mini and that is coming from a person who loves my Mini.
Had to take my Mini Cooper S with jcw package in to correct a service light issue. Was carbon build up on the valves. Cleaned it for 1500. 00. Drove it about a month and the turbo bypass solenoid valve failed. Back to the Mini cooper dealer in clear lake. They replaced the solenoid and did a oil change for 550. 00 got it home and noticed it had a faint smell of something burning. Thought it could be they got some oil on some parts that get hot. One week after the turbo solenoid was replaced I noticed a oil spot on my garage floor. Raised the hood and the turbo had a oil film on it and the air intake supply on the turbo was loose and practically off the turbo. Took it to dealer. They said look like oil drain bolt leaking. Replaced it but the also cleaned the oil off the turbo? not sure why. I didn't tell them it looked like it was leaking. Maybe they knew? drove it home and it still smelled like something burning. Looked under the hood and the turbo was covered with oil. Back to the dealer. They can fix it for 1200. 00 it is the turbo oil feed supply and return line. Also the oil deteriorated the air intake line and caused it to deform so that it no longer will stay on the turbo intake. After further investigation looks like the turbo oil feed line is a major issue. Multiple reports of this failure. I also saw a service bulletin for the heat shield on the oil feed line. But they failed to do the install on mine. Even though I have had it in for several services since the bulletin. There is definitely a issue with the oil feed line to the turbo. Won't be purchasing another BMW product. Will not be using this dealers service if I decide to keep the Mini.
Cpsc: i1350251a. Mini Cooper S 2009. Consumer stated that the car was brought new and have several issues. The consumer stated because of the late recall, issued by BMW, the oil supply line was damaged and started to leak.
Turbo oil feedline / pipe failure, resulting in leak, possibly due to excessive heat.
There is a leak at the oil supply line leading into to the turbo housing. This is a major oil leak and safety hazard. Oil leaking onto the hot turbo can potentially cause a fire. Aside from the potential fire hazard, the leak, had it gone unnoticed, could have caused an engine failure. The local Mini dealership said the replacement would cost around $1,000 with oem parts.
Turbo oil supply line from engine to turbo leaking excessive oil requiring replacement. Poor engineering design of compression fitting led to premature failure. Continued operation of vehicle with this condition would result in catastrophic engine and or engine turbo failure. Mini of marin was notified of the ongoing issues and were told they hadn't heard of the issue. Car smokes up if driven slow. Must be addressed in recall.
The oil input line to the turbo has started to leak. The car is currently sidelined because of chance of fire or failure of the turbo.
The oil feed line for the turbocharger leaked enough oil to allow enough smoke into the cabin to greatly decrease visibility. The fitting is comprised of a bango fitting that is crimped to the feed line with an o-ring in the feed line. The o-ring is the component that failed and my engineering back round has led me to the root cause being that the o-ring has seen enough thermal cycled to deteriorate leading to the leak. This is unacceptable from a reliability standpoint and I know that I am not the only Mini owner that has had this happen to them. Mini needs to own up to this design flaw.
Turbo charger oil feed line - very poor design crimped tube with an o-ring seal failed in very hot environment and caused large oil leak onto hot catalytic converter. Stopped car before fire started. Dealer wanted $1,300 to install a new $50 oil line of the same poor design. Every single 2007+ Mini Cooper S has a similar oil line - they are all failing at fairly low mileage - no exceptions. Mini should redesign this part and issue safety recall and re-imburse those that already paid to repair oil line.
Turbo oil lines leaking oil. No check engine light has being activated.
I drove less than a mile and smoke started coming out of the engine. The turbocharger was leaking oil onto the engine, which almost caused the car to catch on fire.
Turbo oil supply line from engine to turbo leaking excessive oil requiring replacement. Poor engineering design of compression fitting led to premature failure. Continued operation of vehicle with this condition would result in catastrophic engine and or engine turbo failure.
The contact owns a 2006 Mini Cooper S. While driving approximately 7 mph the low oil pressure sensor illuminated on the dashboard. The vehicle was stopped and the contact added oil to the engine. The vehicle was taken to an authorized dealer and while driving approximately 75 mph the vehicle stalled. The vehicle coasted to a stop and upon restart the contact was able to get the vehicle to authorized dealer. The authorized dealer told the contact that there was a small leak within the engine. The vehicle was not repaired. The failure and current mileages were 74,500.

Failed component 1: lower control arm bushings diagnosed at dealership as bad and oil leak is due to faulty o ring. Failed component 2: power steering total failure. Dealer stated this was due to poor design of steering pump fan (poor placement of the fan). Dealer stated there was a possible recall regarding power steering failure due to this poor design possibly pending. Work to repair these failed components has not been completed pending a dealer recall. The car is not drivable.
