2009 Mini Cooper Owner Comments

problem #4

Jul 242014

Cooper 4-cyl

  • 44,000 miles


While idling at a red light, vehicle rpms varied dramatically and the engine shut off. Vehicle was able to be restarted and moved with the check engine light illuminated. Upon further investigation the valve cover was found to have a vacuum leak, which has become a common issue with MINICooper S models.

problem #3

Cooper 4-cyl

  • 33,000 miles
Fire did not occur, but there is a risk. Many MINIcooper 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 MINIhas 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 MINIcoopers do not have an oil sensor.

problem #2

Cooper 4-cyl

The fuel line leading to the injector rail was damaged by the heater hose support bracket. The abrasive edges of this plastic bracket rubbed a hole in the high pressure reinforced rubber hose and created a fuel leak in the engine compartment. This was discovered after the car was parked in the garage and gasoline fumes were very strong after exiting the car. I read up on the internet and discovered another similar case, and I traced mine to the bracket as the problem. When ordering the new fuel line, I was informed a new support bracket for the fuel line was recommended when changing the line (approximate total for line and bracket - $135). BMW in indianapolis has sold four lines this year so far. When the new parts arrive, I will assess if revisions to these part(s) have been made under the "radar". luckily my garage door opener/exhaust did not ignite the fumes/fuel. I have photos of the hoses/bracket and fuel line interference, and fuel trail on them if needed.

  • 29,643 miles
The contact owns a 2009 MINICooper S. the contact stated that the check engine light would illuminate on the instrument panel and the vehicle would make a loud noise. The dealer diagnosed that fuel line was clogged, which made it difficult for the fuel to flow freely. The manufacturer was not notified. The vehicle was not repaired. The failure and current mileages were 29,643.
