Recently brought an A6 Avant 2.5tdi Quattro 2001. Noticed that when driving along motorsways etc the water temperature barely goes above 60, however went i sit in traffic the temperature goes between 70 - 80.
My Passat always used to be at 90, either when driving along motorways etc or if sitting in traffic.
Does something seem wrong? What can i do to check / solve this?
Thanks for your help.
