I’ve got an ‘07 NC1. Overheats when I stop at idle after driving for a bit. Not even too hard, just regular motorway driving. Even worse when I’ve got the air con running. Only thing that keeps temp normal is cranking up the cabin heater and blasting all the engine heat into my face. Sucks during the summer. Recently flushed the coolant system. Helped a little but still having the issue.
I’d guess it‘s one of 4 things
>A bad relay
>Bad temp sensor
>Wiring issue
>Radiator fan problem
Anyone had a similar issue?
