The image you see above was taken from a F01 750 owner over on Bimmerfest. His car had started to smoke badly and after one repair of a PCV system had to go back and have the entire engine replaced under warranty because the engine hydro locked and shot a con-rod through the block. I’m sure some of you may be familiar with this story and of the shittyness that is the N63. But what are some of your own or stories you’ve heard about wallet emptying repair stories with BMW?
