hdi engine shuddering when accelerating

Post by cajunmart »

my hdi 90 engine shudders when moving from stationary, or even if i let the clutch out slightly (biting point)
its gets worse every day, but once its going along its fine. could this be a worn torque mount?

thanks in advance.

The 90 is not renowned for clutch problems but you can never rule this out. The rear lower engine mount (with the drive shaft passing through it) can also cause this shuddering - can you detect vibration as the car rides over a crest in the road?

is this when accelerating, or just when coming off the clutch?

I'm with Welton, probably an engine mount but it could also be your friction disk's soaked in oil.

It's the mount, early stages of failure. The top mount seems most the most common to wear.

I hate to say this but it could possibly be the thrust bearing in the clutch too :(

Thrust bearings usually make a god awful racket when they're on their way.

Hopefully James will drop by and read this thread, he's the resident genius!
Trouble is he defected; sold his 406 and bought a Passat :roll: :lol:

knackerd clutch pressure plate, a worn thrust bearing (or release bearing) will give you a high pitched squeal or rattle at idle untill you depress the pedal
