ChatYTB Posted May 6 Share Posted May 6 (edited) Hello I have Audi A3 sportback 2015 quattro and I was wondering about haldex differential rear axle transmission. I have pre facelift model and I want to know if that rear diff is one complete unit ? So its fluid inside is spread across the whole ? Because I have total 4 screws / bolts which I can unscrew.. Please see the picture. On left side is lower bigger bolt for drain and upper for filling. then on the right here is another screw for drain and for filling .. are the haldex and axle separated ? does haldex has different fluid / liquid and axle different fluid /liquid ? Thanks Edited May 6 by ChatYTB Quote Link to comment Share on other sites More sharing options...
