Engine shaking seat when idle after CAMBELT CHANGE BY VW

[bacillus]

I believe that they loosen/remove the engine mount when changing the cam belt so it could be feasible that the mount bolts have not been torqued to the correct value.

Good point, I was wondering if the engine mounts got played with as part of this.

Could be the dual mass flywheel on it's way out causing the engine to shake and could just be a complete coincidence?!

They checked the torsion value and it seems to be exactly zero so the timing belt is fine.
Could be a mount or dmf but its very very unoticable and comes sometimes and ive read alot of people with tdis have it.
It seems better
Thanks for the reply guys guys!!

unfortunately it is a trait of the tdi's and it can be sorted to an extent but its always there...I had the feeling like it was miss firing but when I put the bluefin map onto it it went away but I still get the odd little shake now and again.

The EGR valve at the front of the engine is one of the culprits it has a flap inside and after time if not cleaned will clog up and cause starting and running problems, also the threads in the manifold at the top of the EGR valve are very fragile and once threaded are a pain cos the EGR will be the weak spot for pressure leaks.

The only other thing ive noticed with these engines is the lower coolant pipe can break down due to oil and road grime and then the coolant loss starts.

I am having the same problem, only had the car a few weeks so hoping to get it fixed under the warranty. I have a 2.0 gt tdi and it has had the cambelt changed by vw.

This shake would get worse with acceleration but almost disapear when the clutch is depressed. so i doubt this is the problem.

Sounds like cam timing to me.

Well it goes straight away when moving..
I only feel it on idle
The timing torsion value is exactly zero..
I have the coolant temp sensor and egr valve error. It must be caused from that.

Find someone with vagcom, raise the idle by 80-100 rpm and the problem usually dissapears. Ive seen this problem many times and found this is the easiest way to solve it.

A faulty dual mass flywheel is more likely to show symptoms (juddering) under acceleration/load and will dissapear with the clutch presses
