I have just bought a 1999 a3 quattro. It turns out it has a bad history! The HPi says 6 speed and its a 5 speed box in my car, maybe a misprint or did these come 6 speed?? Also it has a AUQ instead of an AJQ engine fitted. There is no wire for the timing chain tensioner on my loom and the oil sensor in the sump has no plug anywhere i can find? Its supposed to be 180 BHP, what turbo should be fitted and how can i check? Thanks in advance for any help.
