Possibbly one for Tame Technician, vibration at the front
Discussion
Hi
The car is an A6 2003 with the 2.5 TDI v6.
The problem I'm having is a small amplitude vibration coming from the front of the car noticeable mainly on motorway. The vibration is enoying and spoiled the ride. It make the satnav vibrate for example
I feel the vibration with my feet, not through the steering wheel and not through the seat.
The intensity and frequency of the vibration are the same when doing 60mph or 80mph but the intensity seems to be greater when accelerating.
During the last service the front wishbone link near side and off side where changed.
I am wondering if the upper front and rear link should have been changed at the same time.
Would a worn front and rear link could cause a vibration which shake the front of the car?
Is there a way of checking if the links have abnormal play in them?
Thank you for your help

Hi thank you for your answer
113K miles last service in February 2009.
Front tyres are more or less new, the front where change around March 09 which was bout 10K to 12K miles ago.
If it was the disk the amplitude of the vibration should increase with speed and I should feel it when braking.
But it is not the case.
It is a very strange vibration and I would really like to cure it.

Sorry few more details
It is FWD car
I did swap the wheel round and it did reduced the vibration for a while. What was discovered at the time was the front near side alloy was not round this is why I have a new alloy at the front.
I cannot discern if the vibration are coming from the near side of the off side.
The back tyres are 2 weeks old.
No noise just this annoying vibration

It's a CVT gear box! so no flywheel.
Can you correct me if I'm wrong, if it was a wheel/tyres issue I shouldn't I feel it through the steering wheel?
I am getting confused now!
No not stationary, I'm use the cruise control quite a lot which is easy to keep a constant speed with.
TT what would be the consequence of driving with worn foward and back upper suspension arms?
