My 2000 Bug TDI's blue temp light comes on randomly after the car has been driven for over 30-40 minutes. The light comes on and then just as randomly goes off.
The car has been at the dealer for three days. They've been driving the car around with the hopes of seeing the light (literally). No joy. They don't think anything is wrong. I'm assuming there must be a loose connection somewhere but I would think the dealer could figure this out. Would appreciate any input on what do I do now?
