Question about BMW 320D SE - can someone help?
I've recently bought a late 2001 BMW 320D SE, and the car is fantastic - one small problem though, is that, when idling in neutral (or in gear with the clutch in), at traffic lights etc, the revs seem to waver every 10 seconds or so - like it's sitting at 800 and then, just for a few seconds, will drop to 5 or 600 the rev counter needle will shake for a few seconds and then recover again.
Appears to be OK when driving...
I bought the car with a 3 month warranty, so if this IS a problem, I'd like to know what it is before I go to the garage... Car is a manual with 60'000 miles.
hopefully someone can help!
