Hello Gents,
I just bought this 2001 M5 and sometimes it makes this clicking noise that goes away when the car warms up. The noise sounds like its coming from the engine head, but I am not sure. The car has less than 12K on it. I called the guy that I bought from him and he said that the noise was normal. The thing that worries me is that sometimes I don’t hear the noise even when the engine is cold. Does anyone know what this is about?

this it comin when those cars arnt drivn alot basically drive the car more and thi should go away take it out and beat on it for awhile and this will most likely go away

hva hydraulic valve tappets, the sound may never stop coming back.
