I have a had my 2000 m5 for about 2 years now. it has been a flawless performer on the track and the highways!! I have 44k on the engine.
Recently I noticed a harmonic engine vibration when I decelerate from 5000rpm down to 3000rpm. Nothing extreme but it has gotten worse recently. Is this common with anyone out there??
One other comment...my engine has a "tapping" sound at idle. it is more noticeable when standing on the drivers side. This sound has been consistent since I bought the car. I have asked my BMW service manager about it everytime I bring in the car. They keep saying its normal.
Anyone else have a similar tapping sounds?
Thanks.
