I have an '07 A4 Avant that I ordered with the MT6. for about the past two years I have had issues with jerking at full throttle and it is getting worse. My independent mechanic says it's the clutch, but it doesn't feel like any clutch slippage I have ever felt. I feel like it's more in the turbo - like the wastegate pops open and I lose power. It has about 185,000 miles and I am still on the original clutch. My guy says it's a dual mass clutch and they behave differently. I have kind of learned to live with it by feathering the throttle, but it's beginning to drive me crazy! Any advice would be welcomed!
