I purchased a bosch 0392-022-010 pump to put on my 2003 E55. I went to install it yesterday with a heat exchanger yesterday and low and behold, it already had the 392-022-010 pump on there! What puzzles me is that this vehicle is a 2003, and everything is bone stock, not a single mod on there. So my question is, is there any chance that this is the stock pump on the car or has it been changed out previously? Everything from the connector to the hose clamp tells me this was the factory oem pump. What do you think? I put the old one back on and this new one is going up for sale!

Probably warranty work done at some point. Have you owned the car since day one?

I actually have only owned it for about 6 months or so.
