2000 Audi A6 review from North America

Enormous thump and jarring is felt (car slamming itself into gear or turbocharger behaving improperly).

An enormous "thump" occurs when, after the car has downshifted upon decelerating, I give the car a little gas (occurs in the low gears when, say, I come upon slower traffic, slow down, the car downshifts into 2nd or 1st gear and then I give it gas). Basically, the car is slamming itself into gear, or the turbocharger is not working properly, and the result is an alarminging jarring effect.

3 separate dealers have been unable to diagnose a problem, alleging that this is simply a normal occurrence ("aggressive gearing" is what one dealer termed it based on the intermix of regular and hydraulic gears - spare me) as a result of the engine distributing power to all four tires. The last dealership determined that it is a turbocharger byproduct that results from the car being "wound up tightly and ready to go".

Has anyone else experienced this??? Please let me know. I have thus far identified 2 other Audi owners with the same problem with their A6s. Audi USA is of no help, and the dealerships are even less sympathetic. In fact, one service person lost his job for keeping my car for 3 days because he recognized that it was a problem and wanted to try to fix it. His boss disagreed, telling me that nothing is wrong with the car, and terminated the employee in the process. Something is going on here, and I want to get to the bottom of it.
