Hello, everyone. As title says... My "quattro system" don't work for the past few days. I notice that something unusual and wrong continue to happend, while driving on straight lines especially last night. The car was spinning front tires too much, here where i'm living is now snowy. So, i decide and take the car on parking lot and voila, what to expect... rear tires are on winter vacation, no one there. Last week i was having some fun and everything seemed to be really good, donuts were the best fun though. Anyways, i just was to my second and reserved mechanic and thats what VCDS read and found He suspect the pre charge pump, but the car is not lifted yet, the earlier can be looked out would be in monday. Last night i spend around 4 hours of reading possibilities for the exact reasons that can caught haldex to not work.... I hope it's not something very big.. Every single, guess, opinion, knowledge is very welcome ! Thank you, Dimitar! Ps: I'm sorry if there's something wrong with my english and it's incomprehensible!
