kiwi6539 3 Report post Posted December 4, 2008 Hello Can anyone give me some advice for my E34 89 530i My fuel gauge isn't working properly. It gets to a 1/4 tank and just drops and light comes on when there is still fuel in tank. Also just filled it up and it won't go all the way to fill sits on 3/4 any ideas what to check first before spending money. Also when it idles it won't just idle normally its up and down only by a 100 or so but its annoying. And has anyone had trouble with there heater having a mind of its own? Any advice welcome Cheers Quote Share this post Link to post Share on other sites
