It seems I need to have a new water pump fitted. Can anyone tell me if diagnostics software show up a faulty water pump or are an official Audi garage going to actually have to strip the car and look at the pump... and charge me for all the labour hours? Also do Audi have an estimated time for the replacment of a water pump and cambelt. I'd appreciate it if someone could help me with this as I would like to be forearmed before taking the car to them.
