[928uk] Vibration

[Paul R Smith]

Can you rock the engine from side to side?
If not, your engine mounts are collapsed (so are solid) and need replacing.

> I have a 1991 S4 which is suffering with vibration at 2000rpm and 3000rpm.
A local Porsche centre had the car and after changing all HT leads,
ditributor caps and rotor arms due to a miss-fire the vibration remained.
They also checked the torque plate and alternator which were both fine. They
suggested that the vibration is from the drivetrain and said it would cost
approx £4k to investigate further (remove gearbox, diff, axle etc) and could
not garauntee that the this would solve the problem. Has anybody experienced
similar problems or got any ideas?
