One problem related to engine oil leaking has been reported for the 2012 BMW X3. The most recently reported issues are listed below.
Situation when starting a cold engine, a �plume of blue smoke� can be seen emitting from the exhaust tailpipe for approximately 10-20 seconds. There is no engine malfunction light illuminated (no� turbocharger boost faults are stored) and no drivability issues are detected. Cause when the vehicle is parked overnight the engine oil pressure will equalize, this may cause engine oil to leak past the turbocharger �exhaust side� turbine seal due to carbonization of the turbocharger sealing ring. This is the same issue impacting BMW n20 engines that BMW has issued a technical service bulletin and extended warranty 10 years/ 100,000 miles. The n55 engine (6 cylinder, turbo) has not been included in this extended warranty although defect is the same and may impact emissions.
