    Get under the car and try and locate the source. If it does appear to be the water pump then I'd be straight back to audi telling them to put it right as the belt and pump should still be under warranty.

    Not necessarily the water pump though - could be a split hose or where hoses join or a connection on the radiator. As Audi Doodah says have a look under the car with a good light.

    The car is now back at the dealer and i kinda get the feeling that even without looking at it they are building me up for bad news like it's not the pump it's something else

    So the question is what else right on the front of the engine could leak coolant, is there a flange or some other part that i am not thinking about, as far as i can see on etka it's just the pump, those who have replaced a pump may have a better idea

    thanks

    No manufacturing process is perfect...wouldn't be cost effective. There will always be a very small percentage of failures expected, something like 0.002% on a mass production line. You just happen to be one of the unlucky ones.
