Hi all, new B8 A5 owner and first time poster here. I picked up my car a week ago and noticed something odd. Regardless of engine temp, and in cold weather, the main rad fan runs all the time. The coolant temp can only reach about 65 C when driving. I've found some people have a similar issue and it sounds like a coolant temp sensor could be bad, or water pump/ t stat. Anyone able to chime in?
