jerro Posted December 3, 2012 Report Share Posted December 3, 2012 Hi all, well just another techno question, this time it is the fuel gauge on the dash. The needle shows the fuel level half the time but the other half it slowly goes down towards empty and stays there for a while when you are driving, the next time you glance at it the needle has moved back up to what i assume is the correct level. Anyone had this at all and any pointers in where to check the problem please? When you put some diesel in at the garage the needle does go up to roughly where it should be but slides down after a while then comes back up!-- Thanks as always -Jerro Quote Link to comment Share on other sites More sharing options...
Bean Posted December 3, 2012 Report Share Posted December 3, 2012 Check the wiring and the plug to the gauge on the tank... If the wiring or the connection isn't very good, or the tank / gauge isn't grounded well you can get all sorts of issues. Rabin Quote Link to comment Share on other sites More sharing options...
andrethx Posted December 3, 2012 Report Share Posted December 3, 2012 rabin's right, wiring is your #1 culprit. less likely, but something else to check, is your fuel level sensor. it could be rusted up and sticking... andré Quote Link to comment Share on other sites More sharing options...
Bean Posted December 3, 2012 Report Share Posted December 3, 2012 Diesel is quite oily and it usually preserves tanks and assemblies incredibly well for years and years. I've got a 504 diesel tank it looks new inside. So I'd focus on the wiring and connections - only way that the gauge itself would be suspect is if it wore out and physically was breaking up - so it'd be the last thing I checked.
