Hi, I've just had my 2003 A6 2.5TDI for 2 days and noticed the temperature gauge on the dash always stays at a constant 60 degrees. There is no overheating and the car runs fine. I read up on other threads and it seems this is a common fault and was wondering if:

A - I shouldn’t worry about it
B - Get this fixed ASAP as it can be dangerous to not worry
C - Get it fixed when I notice the engine fan keeps coming on for overheating

Thanks in advance.
Love my A6!
