The weather here has cooled off over the last few days after a bizarre late fall warm spell, and strangely this seems to correlate with the fans staying on after I shut the RS6 off, or maybe it's just a coincidence. Do I have an after-run gremlin?

For example, I moved the car about 20 feet yesterday, after it had been sitting overnight outside. The engine only ran for 30 seconds, yet after shutdown the fan(s) came on and stayed on longer than I had patience to stand there. The fans do eventually shut off. They also came on after a 30 minute drive.

My Ur-S4 has an after-run system, which is triggered by engine coolant temperature. It rarely turns on, and when it does it doesn't start until the engine has heat-soaked for a few minutes after shutdown. The RS6 either has a totally different system, or something is broken on mine.

Any ideas?
