I just sent my e320 in to have the A/C repaired, it was blowing warm air. It turned out to be a bad condensor. While my mechanic was doing this he noticed excessive play in the fan which is connected to the water pump. he says the water pump had a real lot of play due to a bad bushing and i was lucky it didn't fall off. i was surprised it did not leak though. Well anyways my question do you think $900 parts&labor is fair for a new water pump and condensor, oem, not aftermarket crap. My mechanic works a local Mercedes dealership but takes jobs in after hours off the clock. wonder how much it would have been had i gone officially to the dealer?
