Hi guys,

I have an Audi A4, 1.8T Multitronic. A vibration that can be felt on the steering wheel and seat started at around 55000 kms. Each time I brought it up with the dealer during a service, they simply palmed the issue on tyres/runs etc. The car is now doing 122000 kms and the vibration is still present with new tyres, new rims, balancing and alignment. I've managed to take a few pics of the upper control arm bushes and they all seem to be cracked. I've read something about a defective design that was caused by Audi using rubber compound that was too stiff on the B8 A4. I'm new to this forum but I'm curious if other A4 owners have experienced any vibrations and what the cause was. Try as I might, I can't seem to have this sorted out.
