Sorry I'm a newbie and only just noticed that bit
Whats the symptoms out of interest? its usually haldex related problems thats allMy rear diff has gone anyone no how much to rebuild it or a second hand one
please help
Got my rear diff replaced several months ago now after my old one was knackered- pretty sure it was around the £300 IIRC from a low mileage S3.
I expect you can get them cheaper, but the garage that does all my work sourced the diff and recommended it as a good one.
