[s-cars] Fuel Gauge not going to full

[Tom Green]

I'm looking, Peter, but don't find the document yet.  It is a service  
advisory from Audi.  Pretty old now, of course, and I just don't
find it.  Audi never looked at mine, the problem only appeared for a  
couple of fill-ups, and after my cursory look ( I never saw a
wire I definitely identified as a green ground wire) and tightening  
nuts, it never has happened again, other than an occasional
slowness to go all the way to full after a fill-up.  To be honest, I  
have no interest in tank diving, so I will put up with a lot of slowness
as long as it is there when I need it--most of the time.  It was a  
tech bulletin so Audi is certainly not going to do anything now
without just starting the clock for hourly charges and fiddling  
around with everything.

Sorry, I just can't find more, and I don't have access to bulletins  
anymore, but, IIRC, this only applies for the gage that stops at 3/4
when filling up, but otherwise indicates correctly, and never gave a  
good diagram of the wiring, just near the taillight.
