Hi Guys,

I have recently bought a 2001 E39 M5 with 28,000kms, after having an E34 M5 for a little over 10 years.

One thing I have noticed on my E39 is that at idle engine speed, A/C off, there is an intermittent vibration, almost like a buzz. Also, the idle speed oscillates every now and again, say from 600rpm to 900rpm. The car pulls fine and does not stall.

Is this buzzing/slight vibration at idle normal? Is the idle speed oscillation normal too?

Would greatly appreciate some advice.
