Hi all, popped into a friend's garage today to put the car on a dyno, just out of curiosity. My car is a 2009 (my10?) tdi Quattro. The dyno is a 4wd unit however after hearing of the haldex quattros not liking them we ran the car in 2wd mode by pulling the haldex fuse. However this was still presenting problems, the abs kept cutting in, almost like a limp mode. We tried pulling what we thought was the abs fuse however the car wouldn't then start. Are we missing something obvious?
