Do we know for sure that the cylinder head change solves the problem long term
because of its new design? Can people who went through this with their dealer
verify that this is a new design? Or perhaps our BMW techs I've seen post in the
thread? TIA.
I had the bleeding procedure done 5 times per the SIB. Initially and while I was
at the dealer, the engine did sound better. By the time I got home the ticking
was more intense than before and the engine sounded like a diesel again. They've
been very good so far though and after having a long discussion with the service
manager they assured me that if the noise persists to bring the car back and
they will open a PuMA.
