Hi, my partner has had her 2009 A3 TDI 140 for about 5 weeks and the dreaded engine management light came on. I expected it to be a DPF issue but it actually turns out to be a Coolant Pump (which I am assuming is a water pump) fault. Two questions: The cambelt was changed by Audi 13 months ago, do you think they would have changed the water pump and would it be acceptable for it to be faulty after 13 months? Secondly, a local VAG specialist has quoted £172 to have a new water pump fitted, is this reasonable? Thanks in advance. David.
