Engine Oil Leaking problems of the 2014 BMW X3

Faulty turbo hose causes oil to leak and smoke from engine. Seems to be common problem that I wish BMW would address.

The oil-feed line for the turbo on the (n20) engine of the 2014 BMW X3 was replaced due to leaking oil into the engine. On cold startup a plume of blue/white smoke is seen emitting from the exhaust tailipie for approximately 30 seconds. This BMW X3 has the standard, common n20 engine. This issue has been addressed by BMW for model years 2012 and 2013, but not 2014. This turbo-oil line failure is a well-known and common defect. BMW has issued "service bulletins" and extended the warranty on the 2012 and 2013 models for this express issue. The service bulletin is attached. BMW has been contacted and are refusing to cover the 2014 model although it is the same engine defect. The repair part includes a redisign of the original part and now includes a check valve. This is a clear example of defect in design. BMW verbage is listed below: the �new� engine oil feed line part numbers listed above incorporates a �check valve� on the engine side of the engine oil feed line. The check valve eliminates engine oil pressure equalization and the consequential engine oil leakage past the turbocharger's �exhaust side� turbine seal. On contact with BMW I could not get a clear answer why the 2014 model was not covered, but I did get BMW to confirm that the engine and the original part are identical to the defect parts in the 2012 and 2013 model. Would NHTSA open an inquiry on the 2014 model n20 turbo oil-line defect please? thanks john awad.
