I have an issue with my 2002 a6 2.7t

When cold it drives perfect, but once I have driven a little there is a small noise and a little vibration in the steering wheel (when driving and standing still) when I turn the wheel. It is both around dead center and when turned more

fuilds is in good condition and there is plenty of it.

Any ideas what can it be?

 

check these ..... control arms, hubs see if the rubber has acrack those are what tend to go the most, if you turn the corner and it makes a grinding noise it is the hubs, other wise i would say control arms.

 

Also check the axle CV joints. These can click and feel "rattly" when bad. The front control arms, asredimag said, are prone to loosen up (design flaw that affects A6, A4 and Passat).
