Since you sent this to quattro as well, you probably already have a 
response, but oh well.

Possibly, heat is not the best thing for electrical connections. 

b) that's not how you pull codes on a Motronic car. See 
http://www.sjmautotechnik.com/ecuf20v.html#fcthree, newer cars use the 
diagnostic connector in the driver's footwell.

1991 200 quattro, 110k, shiny until the next dust storm
1988 GTI 16v, 211k, ~1500mi road trip coming up this weekend

Saw a nice pearl 91 20v Avant with eurolites on Idaho Hwy 55 headed to 
McCall yesterday afternoon. So surprised by the euros and 20v-indicating 
fender flares I didn't get a look at the plates. Anyone? I haven't seen a 
20v Avant locally before, there are a couple other sedans and a nice blue 
V8 5-spd.

Took a friend by the dealer (she was unfortunately looking at Toyota trucks 
to trade in her Golf, but fortunately couldn't find a clean, cheap one) and 
the 17-in five-spoke wheels on the A6 4.2 look *really* nice. The 
twin-spoke ones on the 2.7t don't do much for me, though. That car's brakes 
look kind of small under there...wonder if they fit over UFOs...
