Moin! Here’s a question about performance testing at Haldex Quattros. I just got a chip from Tuner of my trust and a performance test will be carried out next week. Now I’ve already read here that a plug is pulled at the rear of the Steurer unit of the Haldex coupling to turn off the Haldex so that the TT is virtually tested as a front-wheeler… Is this correct? Can someone describe his experience to me? Comment! Greetings Dirk
