Hi all
Audi A6 2.0 TDi 2010 (60 plate)
I had a service and timing belt done a few weeks back and since then the engine fan starts up immediately the engine starts and stays on until it's switched off. No over-run, that I've noticed.
Audi told me that the DPF sensor had a fault and was causing the problem. Got the job done, collected the car and guess what - the fan is still on all the time. Sods must have known it wasn't fixed. I'll be taking it back, but in the meantime does anyone know if there is anything that could have been damaged during the timing belt work which could b
