Hi guys. Just travelled to London and back which was 400+ miles. Engine never reached 90 degrees on dash. I would say the needle, on average was stuck on 70 degrees, between 50 and 90 on the little gauge. I got 47mpg on this trip. Not sure what the problem could be.
I have a 2011 Audi A4 Avant 2.0 tdi 143bhp
please help, many thanks
