The bosch 044 has been discontinued by bosch a few years ago. The replacement they make is slightly different, and I don't recall the part number at the moment. It's on their website. Some shops may have old stock still on the shelf, but if you do some poking around on the web you will find that there are a ton of fake 044 pumps on the market. There is a way to find the difference if you look hard enough. Be cautious about anyone selling a bosch 044 pump. I think some of the places selling them don't know the difference. A friend of mine bought one from a very reputable shop, it stopped working after a few trips, we did the research and found out it was a fake....
