This isn't for an A8 (or even an Audi), but with the number of car geniuses here and everyone's overall helpful nature (and the fact that I haven't seen an "old Dodge van" forum equivalent to this board, I thought I'd throw it out there.

My dad's 1992 Dodge van has been having A/C trouble for a long time. It was recently in the shop and they replaced a few things that were apparently leaking (not the compressor) and refilled the fluid.

When he got it back, he observed the following after driving for a while and with an outside temp of 76 degrees. He used a digital thermometer right at the dash vents.

Driving 30+ MPH: A/C air is 53 degrees within seconds

Slow driving (<30 MPH) in traffic: A/C air climbs to 70 degrees within 30 seconds

Stoplight/idling: A/C air goes up to 80 degrees within 2 minutes

Note that the A/C air temp when at a stop is HIGHER than the outside air temp.

Any thoughts???

The condenser is the heat exchanger in front of the radiator, the electric fan is probably not connected electrically because of work they did (plug the connector back together) or it's dead and needs replacement.

With in adequate air flow over it, it can't transfer heat out of the system, and with the compressor adding energy to the system when it's on, it causes the temp to go up.

That's my guess.

Yup, that's most likely.
