hi Guru's .How shall i see the different of engine whether its a M52 or M54 engine. Which engine is recommeded to buy if i am getting a E39 525i . Lately i saw a E39 525i 2000 model , is this a M52 or M54 engine . Please advice . Thanks Regards
525 comes with a M54 while 523 comes with a M52.. after 1999 BMW did some up grade to the M52 so those engines are called M2tu.. M54 engine share most of the M52 design with many more improvement. M54 engines are better engines and ofcos newer ones. M54 are also found on the early introduction of the E60
X Benz is correct. In addition, M54 engines are fly-by-wire throttle system which offers better throttle response. Yes, the early batches (2004 to early 2005) of E60, 520i, 525i and 530i are running on M54 engines.
hope you manage to learn and understand more about your doubts from people here and in future, maybe you could guide and share your experience with the new joiners...cheers
