Our '93 90 has had this stench from day one, no sign of engine
performance problem. Dealer said they all do that for 10-15k mi. After
15k, dealer said Audi can't figure out what to do about it. Seems
slightly less stinky w/ premium, but the car should not need this.
We've tried Mobil (use now most of the time), Amoco, and Shell, at least
two tanks full in a row for each test. No TSB's on this '91-'95,
either. Car still has 3 mos on 36/50, not to mention emissions
warranty, but we've lived w/ it this long. Should I bug them for a new
'91 V8 5-spd
