    Hi All

    I have a rough running audi tdi 2.5 on idle and at 70mph to 85mph and would like some clarification. The cars mounting are all fine this is a purely a running issue with the engine.

    Some of the suggestions are as follows:

    1) actuator
    2) Injector blocked
    3) Wiring loom???

    Any help would be appreciated. Thanks

    Hi Mike M

    I have heard this on another board regarding this. Ive just had the engine rebuilt would it be that they have not put something back?

    They certainly do have a release bearing. I have recently replaced mine and it was a 750 bill for dual mass and 3 piece clutch kit all LUK fitted with a gear box oil change

    hi

    Thanks for responding just to understand why would it do this? The car is a auto and one idle it shakes no clutch engaged and at 70 80mph just trying to understand why this happens.

    This turned out to be a bucked rear wheel. As a temp fix had the wheel balanced.
