I've never droven Audi Q before. I picked up this A8Q '97 4.2 last 2 weeks ago. It has 108,000 km. and looks like NEW. First there was a BIG vibration when drive only 80 Km. Dealer change 4 new tires and solve the problem immediately. It has P6000 ( 225/60R16 ) before, and now has GoodYear HP ( same size ) with 97H rating.

But now, when I drive ( start from complete stop ), I feel the car is ( pulsing )on the engine and on the wheel. But, once you step on the accelerate padel, the ( pulsing ) feel is gone immediately. When you slow down before come into complete stop, then the pulsing is coming back.

Any idea??? Is it related to the transmission?? Where should I check first??? Any A8 owner has ever encounted this problem before??

From what you've said so far, this sounds like a new problem. At what speed does it vibrate, from 0 to ??

Do you feel it vibrating in the same speed range when either starting and stopping?

This is a similar problem that I experianced when my outer tie rod ends went bad. It is easy to check this so I would look at them first.

My tie rods are going out too and this happens to me. Does your stearing feel loose?
