A few months ago I had to replace to the fuel pump/sender on our 2003 330xi. Right afterwards the fuel gauge would not read correctly, so I replaced the sender on the drivers side. Same problem.
I just filled up and using the diagnostics menu I am getting these values:
Menu option 6.0 : 95300
Menu option 6.1 : 395
Menu option 6.2 : 264
Any thoughts? Could it be the gauge which was working prior to pump failure.
Thanks
This happened to me too - and it was because the float came off the track just enough to cause it to read incorrectly. I removed the pump and freed the float but it happened again a year later on a 1/4 tank. Inexpensive Fuel Pumps are just that - inexpensive.
Yeah, I thought about that also. Might just keep using the trip odometer.
Thanks for the reply.
After I filled the tank, the gauge went to just a bit above half. In the week since, its crept to the full level. As I said, I know why it's doing this and when I get to a 1/2 tank, I'll remove the assembly. I'm thinking I'll take the pump that is in now and put it into the original assembly, which has no issue with the float sticking.
I had a similar issue. My solution was totally filling the car tank 5+ times, the fuel gauge started to read again. Maybe because of some misalignment as said, maybe of some rust, maybe...I don't know.
After that periodo of "uncertain", it happened once a time in a year.
I had a cheap made in China pump in my zhp when I bought it that would show weird levels all the time. Swapped in the arm and a track in from a VDO unit and it's been showing very accurate data ever since. Of course a I carry a brand new spare in the trunk just in case.
