This is the only other current problem I'm facing with my car right now other than the airbag light. When my fuel gauge gets to a quarter tank it is actually empty. I found this out the hard way when I ran out of gas. It is something I can get used to but I find it a bit annoying. Does or has anyone had a similar problem with their E38? If so is there a quick fix to this? If it's going to cost me an arm and a leg to fix I'll just fill up at a half a tank all the time. If anybody could suggest something to help me out with this situation I would be greatful.
