N63 program
I just took my 2012 550i in for evaluation. The service person indicated that unless it needed a new engine, BMW will perform the evaluation and repairs at their cost.
Basically my car is using oil like crazy, smells very rich as I think the O2 sensors are reading the excess oil as gas (carbon) and is burning oil as the engine heats up. Lots of blue smoke.
What should I expect from the dealer ?
Thanks
