Well - mine is 2009 A3 with 116 000. Only oil and filter changes so far.
163k miles..not km
Not sure how long she is going to last with a BT setup strapped to the engine.
Sitting at 104k now. Only have had it in drive twice since I've owned the car. Always drive in manual because I hate the way it shifts. I literally beat the hell out of my car everyday on the freeway, and when I can get to a track event. I purchased the car with 80k on it. No service records from the original owner. I have been changing the DSG and Haldex every 10-15k, since owned.
Only ever had 2 weird situations since I've been driving it. Same situation both times. I was pulling out into traffic and going from first to second it lost all power. I let off the gas since I thought it was gonna die. Hit the gas again to see if anything would happen and she took off.
Aside of that I am amazed by the abuse this tranny has taken from my normal driving style.
