On our 520i the engine is constantly varying its speed - on idle aswell as when driving. The variation is as stated constant, and the engine varies with about 40-100RPM at all times. When driving, the "current/actual consumption" needle varies in accordance with the irregular variation in RPMs.
According to the dealer this is normal - however - on a 520i loaner we had, the engine wasn't varying the same way ours is. Clearly something must be faulty.
Does anyone have a clue as to what might be causing this? May there be a problem with the butterfly valve? Have anyone else experienced this with the M54?
