Hi All,
I have a problem on my hands. I have a B6 S4, manual, about 170,000 km.
I was driving today and once I accelerated from a light all of a sudden my car started shaking and vibrating. Then it kept doing that for the whole hour I drove home.
There was no engine light. It does not happen while I am slowing down and downshifting. It happens when:

- I accelerate past 1,500 rpm's or so, and as im driving (did not try pushing it past 4,000 rpm).
- When I press the clutch to upshift I get this pulsating feel/ sound (TRRR) lol hard to explain.
- Even if im stopped and idling, if I rev the engine I hear it.

Like I said when Im slowing down and downshifting it tends to go away.
anyone have any clue what it could be?

Thank You
