I just replaced the bosch IC pump this weekend. Have approx 36K miles. I'm surprised lasted that long. I wanted to keep bosch, didn't want to have to modify. Process went smooth, thanks to DIY on site. The 5th screw/bolt stumped me for a while. I didn't see this on search, I just dropped the under engine panel and could get to that screw/bolt really easy. Thats, for DIY..
