Hello Touareg peeps. I have an 08 with 3.6L. Today I get home from a short drive less than 5 miles. I park my Treg. I come out a little while later to what sounds like someone's car running in my driveway. I look to see and realize it's my Treg. I pop the hood to fine the Aux fan running quite fast. No key in the ignition. I put the key in the fan stops. Wait a bit with key off fan starts again. The only way I can get it to stop seems to disconnect the plugs. Any advice as to what to look for or check.
