LarryL,
Two of my relatives had brand new Audi 5000, one a S version and one a Quattro, the S version needed new front end in under 30000 miles and the Quattro which was driven by an older relative gave myriads of trouble, just like your problems. I had made both of them buy the Audi as it had some edge over other cars of that era, that is the late 80s, things like 4WD, true rust proof body etc. and the 5000 looked really nice, unique for that time, I was also a VW fan at than time since I owned a VW GTi 16V so when they asked me for car advice, the choice was ominous, sadly VW GTi was history for me after the engine developed crankshaft harmonics problem and so were the Audis of both my relatives.
