Any idea where to look first? I know it is usually the thermostat, but I doubt it failed so quickly as it is new a few 1000 miles ago.

My fans both run for a while after stopping without running the car aggressively.

Today at Car Wash the battery symbol showed up and the volt meter dropped to low end of scale, I was able to drive off and a few seconds later the light was out and the meter was at plus 13 or so (normal spot) and thing were fine. So instead of going to work I took it home and use the other car.

This afternoon I hooked up with VAGCOM and when I turned the car on the two fans came on, did the scans, and got that error. I cleared the errors, but I could not start the car. Loose wire somewhere! I am going to let it sit (dry out?) and try again later. I suspect something got wet at the car wash.

The fan issue was BEFORE the car wash so that is something different.
