I have a 2010 Audi Avant a4 quattro I been taking it to get service in a dealership and last month the warranty just expired and after I took it to the dealer they told me that the water pump is leaking and the engine mount is leaking, and it needs a new brakes. I can replace the brakes easily but I want to take care of the water pump. Does anyone know where is the water pump on this car and how hard is it to remove it. I am being given several advise. I was told that it have an auxiliary pump, then I was told that I have to replace the timing belt as well, but now I was told that the water pump is in the back of the engine. Please if anyone can give me an idea on how to replace the water pump I would greatly appreciate it thank you.
