My audi runs great. Its has 170K miles on it. My mechanic replaced an air pump last Friday and by Monday I had a new issue. I noticed coolant leaking. I took it back to the mechanic who fixed the airpump to diagnose. He tells me that the leak is coming from the timing belt/water pump area and in order to get there it takes 7 hrs. He suspects that its the water pump or a cylinder block crack. He suspects it could be a water pump breakdown more than a block crack. A block crack could be a serious issue with the engine is what I suspect.
I think he did something wrong when he replaced the air pump. He tells me that these are in two different areas and that he canbe generous with his time in only diagnosis but not in fixing the problem. Do you think he is right or is he lying?
He recommends that when they open the timing belt cover its best to replace the belt, tensioners, water pump etc. for a grand total of $1150. Now spending $1150 to get to know where the leak is sounds steep. Would any of you do it?
