I've been reading posts from several forums concerning the E46 M3 engine failures for some time now, and I have yet to find answers to my questions. IS THIS engine failure issue a potential problem in ALL M3's? Or is it a rare poduction/material defect that are found in a limited percent of cars produced? Finally, has BMW found a way (whether material or design) to prevent these problems from occuring in newer production cars? PLEASE, if anyone knows answers to any of these questions, please reply!
