The website is www.europaspares.com and it is a VDO part, p/n 224011000280G. It's an easy job to replace it. Although the accuracy is better than the original 240mm sender, in that it doesn't show 0% with half a tank or more of fuel, it is not "normal car" accurate. I still reset the trip distance when I fill up and look for fuel at 200 miles or so.
