Badly vibrating in 3rd gear ( shaking )

Hi there,

I have recently replaced my clutch & flywheel, after almost 114.000 miles done on the previous ones. Just before changing them, those where the symptoms:

- difficulties in getting it into gears, especially when cold

- difficulties in getting it out of gears, especially after a long motorway run

- difficulties with the clutch pedal, as it was staying too low, needed help with pulling it up after each depress action

- at times, the clutch pedal would become to soft, making it almost impossible to engage into any gear.

Previous DMF was a Sachs model, the new one is LUK.

Took the car out of my local independent garage on Monday, all ok, clutch feels a bit soft, probably is the new feeling,but all gears go in, no issues, however, after doing about 100 miles, I have noticed that in the 3rd gear, wile in low revs ( 1250-1500 rpm ),on acceleration, the car suddenly starts shaking badly,unless I very very very gently accelerate through that gear. This symphtom is getting even worst, when on an uphil drive, so bad that I have to drop the gear to make it. The origin of the vibrations is from the engine bay and it does it only in 3rd gear.

To mention that the shaking symptom I had with the previous set too, but that only happened a few days before I knew that it needed replacing , and it was doing it in the first gear only.

Rung up my mechanic, got booked in for a check up, initial feeling is that he is very dismissive at the idea that "there could be anything wrong with the fitted parts, since they are all brand new", he said.

I do also remember that when the previous DMF part was fitted, I experienced unusual noise and vibrations,took it to a skoda dealership who decided that the DMF was faulty!! after only 2000 miles.

After some run-ins with Skoda uk, managed to replace it under warranty, although initially they refused as it wasn't done by an approved garage.

I really hope that one of you good Samaritans outhere, can help me out with some good,honest advice, befor eI get ripped-off by the garage.

Many thanks

Gabriel
