Hi all, I've had my Touareg for about a month now and I've noticed the radiator fan likes to stay on anywhere from 2 to 5 minutes after engine shutdown. No CEL and dash is at 12 o'clock (think that's 200deg) for the coolant temp. While I'm still not certain if this is normal, I've read that there are a couple coolant sensors and the thermostat that are the usual culprits. While I think the sensors will be easy to replace, I couldn't find much about replacing the thermostat on an FSI engine. The earlier V8 has a timing belt that had to be removed to get to the t-stat. Is this the same case with mine which has a timing chain? Anyone know the procedure to replace the thermostat? As always thanks in advance. I've gotten a lot of help already on this forum!
