Im trying to work out if my car has a 3L or a 2.5l engine, according to the wikipedia article on the e90, they changed the engine to a 3L one in 2007. My car is a 2007 and according to realoem I have the n52n engine.
I was also wondering what the technical difference is between a 325i and 330i that both have the 3L engine, is it just software mapping that decreases the power of the 325?
