1.9 TDI 2009 Jetta
Hello guys I have a 2009 jetta with about 200,000 miles on the clock, I'm just after doing a full service on it oil and all the filters including the diesel one. Before the service whenever my car was idling the engine would shake a lot for no apparent reason, after the service for around 100 miles the problem seemed to go away but it just came
back after I drove the car to the shops and back just there, the rpm needle doesn't move at all when this happens as well.

Any help to help me solve the issue would be greatly appreciated,
Thanks

Same problem overhere! ( Golf Mk5 2008 1.9tdi )
Happened just from nowhere when we stopped on toll station.
Shakes intermittently. Now hasn't shaken for 5 days at all.
Not a single code on diagnostics....was thinking about a bad connection on injector wire harness, but diagnostics should show something in that case.

Auto or manual trans?
If you can get a read on the injector balance via VCDS group 13 and the balance is not far off between cylinders (+-1.00mg/str)
then it is probably not due to a faulty injector or cylinder.
It could well be the dual mass flywheel either seizing up or wandering off-center and putting it out of balance.
Sometime the flywheel masses can loosen up to remedy the vibration then seize up again. Thus the intermittance.
