I have a 2003 Audi A4 with 115,000 miles. Just got it back from the shop and they did not fix the problem. They fix the engine light caused by evap purge valve. I was told it was fixed but still shakes. It skakes when the gear is going to second and then shakes when it gets to third. after that it is fine. What do you guys think it might be the problem.

 

how do you know its shaking? is the car the V6 or 1.8t, auto or manual?
