Audi 80 TDI shudders/vibra when cruising - audi80tdi

Hi all
Me again
Another thing I have noticed especailly in third and fourth gear when crusing along gently at around 1500 rev the car shudders. Usually pressing the accltor pedal or knocking down a gear solves the problem. Ive had another Audi 80 TDi before and that was smooth when cruising.
I was told redex diesel treatment may solve it...have used it but no differnce!
Any suggestion at what it could be and approx repair costs???

Cheers All

I would suspect an injector problem. Try and obtain a bottle of Forte Diesel Fuel Treatment and add it to a nearly empty fuel tank and give it a good blast. If the injector is simply fouled it just may clear it. Forte is only available from workshops so ask around.
