Hallihallo,
I wish you a good evening with the request to answer my question with a technical understanding. (That's not mean bad now) Before I throw out money to the window again I would like to know the following: Can you check the functionality of the ABS sensors without the help of an Audi workshop and if so how? In winter I have the problem when I start on snow that the car is trying to turn around its high axis and that despite four wheel? I have to say that even if I give only moderate to little gas it always breaks out behind. On a dry track you notice clearly that the Diffi is locked at the rear, so both wheels run at their own speed, which means safe death for every differential on dry road and finally, when steering is hit, clearly cracking from the front right drive shaft to the left and moderately fast starting. The Manchette of the same, however, is not a loss of joint fat. I think that's the fault of the sensors, only which one is responsible for what. what doesn't work properly anymore if one or more sensors are defective?
Thank you in advance for your answers Martin says.

Moin Martin,

naja sagen wir es mal so. Du kannst es prüfen wenn Du im besitzt eines Osziloskpos bist. Habe das grade hinter mir. Entweder man heb den Lütten auf ne Hebebühne und hockt sich rein und prüft dann mit eingeleter Fahrstufe und laufendem Motor oder Du läßt ein Rad einzeln frei drehen.

Oszi muss dann hinten am ABSStecker angeschlossen werden!
Steckerabziehen und die 4 Sensoren durch drehen der Reifen durchmessen!
Da kommt eine Sinuswelle raus!
Alle Wellen sollten gleich hoch sein!
