Engine Oil Leaking problems of the 2008 Mini Cooper S

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.

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.

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.

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.

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.

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.

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.
