Does anyone find that the n55 335i is way more sensitive and finicky than the n54?
I work on both engines and every time I work on an n55 no matter who's car it may be... once re-assemble is done, I run fault codes and 100% of the time I get some error related to the vanos actuator, boost error, some short circuit, some radiator fault...and it goes on and on. It doesn't matter if it's a simple or complex job...
The N54 on the other hand...no surprises. Fix one thing and it's fixed, no other errors pop up at all. Been over four years working on these engines and that is the apparent trend with comparing the two platforms. If had to choose...I would buy an n54 over n55 in all cases, due to my repair experiences.
