Thanks for the info Tony. I wonder if the "boiling oil" was really just "hot oil" as it doesn't have the Urban Cooling Kit fitted and it will probably still have the "skip fire" mode on the ECU? I cannot remember what temperature skip fire activated but probably about 115c, that would certainly give the impression of going onto one cylinder. I only ever had it happen once before my car was modified for the Urban Cooling fan and it was something you wouldn't want to do often. A good bargaining point for a pretty cheap M3W, for those that have an idea what they are looking at. Another 6 to 8 thousand pounds spent on updates and it would be a good car. Probably nothing wrong with the engine and a post 2014 chassis.
