Hi, I have recently begun to experience some harshness from the engine on my '05 X5 3.0d ..... This tends to happen under hard acceleration in the 2000 to 3000 RPM range .... Whilst I was checking condition of drivetrain incl. driveshaft couplings etc. I noticed that the engine mounts are vacuum operated .... I plan to check out the system but would like to know if anybody else has had any experience with these things?
