My mini is only at 133,xxx miles. Around 130,xxx miles it started, I got off work and was going to head home. I tried starting it, it just cranked until I pressed the stop button. About 4 different service icons came across the screen ( red car saying service, car up on a lift, steering wheel with an exclamation point, and a gear cog with an exclamation point). Disconnected the battery for 5 minutes, hooked it back up and it worked fine, or so I thought. It now runs rough, and I have to disconnect the battery about every 5th-6th time I try to go anywhere because it will just do as before and just crank. Have taken it to 3 different shops, all saying the ecu is bad. I can try to have it reprogrammed for $500-$800, however if they are unable to reprogram it, I am left with the only option of spending $1,000 for a nee blank ecu from mini, which then has to be programmed by mini for additional $$.

Daily on cold starts, the car misfires and stalls 2-20 times before it starts. This has just started happening in the past 3 months.

Total loss of power as I was crossing a major highway, car towed to local bmw certified mechanic, shows timing chain misfire, needs total replacement with multiple components needing replaced due to timing chain problem. 3300$ worth of damage to engine. Apparent problem with timing chain on thousands of mini cooper and they have not called a recall on the piece. This was almost a major accident for me and is causing me thousands of dollars to replace and major inconvenience.

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.
