what the fook has gone wrong wiv BMW engines..
M47 engines grenaded by swirllaps
N42 engine just pants with rattling valvetronic and cam chain guides made of cheese, unreliable and leak oil all over the place.
N46 engine the same mould and eventual issues as its N42 predessor
N53 engines with iffy piezo electric injectors and fuel pumps
N54 engine with iffy injectors and pumps and turbo's made from cheese
a 328 badged 3 series with a feckin 2 litre engine in it?
N47 engines lost the swirlflaps but now developing a serious cam chain issue (big problem cos its at the rear of the engine now)...
