Six problems related to engine oil leaking have been reported for the 2007 Mini Cooper S. The most recently reported issues are listed below.
Oil feed line leaking on turbo.
Rattle and oil leak. Loss of full engine power when restarted. Dealer says its a timing chain assembly issue.
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.
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.
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.
