Wow i have been looking for ages for others that have the same issue as me... posted up a while ago about rough Idle issues but never really got anywhere with it.
I have the same juddering issue while idle, nothing changes if i hold the clutch down so I dont think its the Flywheel. I have had it for a year now and it feels like it is getting worse. It usually comes up when the car is hot... but I can always feel it really badly when I'm on a hill. It feels like someone is shaking the whole car through and it feels like a really bad massage!
My engine rumbles like the video that Gizmo has put up but not as much noise as that. When stopped at a traffic light and i feel the judders I have checked to see if the rev needle jumps or dips but it sits as normal around 900 revs. Again like others the judders calm down when the AC is turned on (It used to go away totally before but where it is getting worse the AC just calms it). If i let the car roll in neutral (approaching traffic lights) i can feel the judders straight away when the engine is hot. Sometimes if i am parked up with the engine on the judders start up and slowly get more violent so i just give the engine a shot of acceleration which calms it down a little.
I do have VCDS so i can do checks but i am still not great with it so i would need to be directed which menu i would need to go to get information.
Car is going in for a full service (not audi dealers
)and brake change tomorrow so will have it checked out then... is there anything i can ask them to check on while its in??
Also dont know if this is related but i sometimes notice a slight 'dip' in my interior lights or headlights where the power seems to be lacking...
thanks
