Failure Date: 03/18/2014

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.

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 .

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.

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 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.

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.
