Fuel Gauge Sticking

Junkie · Post by **Junkie** » Wed Aug 11, 2010 10:22 pm

Well, it didnt take more than a couple of weeks for something else to go wrong......

Filled, yes filled the X at Asda tonight for 94 quid and after the tell tale clicks on the filler and the twitchy round up to the nearest quid fiasco, the gauge reads half full (optimistic) or half empty (me).

As the screen also displayed 138 range, even I know the 4.4 is slightly better than that.

Had a look at some inconclusive stuff on Xoutpost, looking like a sensor problem at the moment.

*sigh

PM Jig - he filled up with petrol in his diesel and got similar issues. Not that you did but sensors could be right!

I have only had this once in France earlier in the year, but whilst driving it, the meter moved slowly up to full (took about 80 miles or so). Never had it before, never had it since either.

No wonder the X5 has electrical problems, my mate stripped a write off and it needed two of them just to carry the wiring loom !!!

They think they did with the Start/Stop button!

There are two tank senders units in the tank that read the level, the range is nothing but a calculation by the computer based on the senders reading x mpg.

The needle again is based of the senders reading.

You can get into a hidden menu on your OBC and actually see those readings.

2 buttons/pins on the speedo one resets the mileage counter (left) and the other to alternate the obc view (right)
1. Press and hold right button till u get TEST NR 01
2. Press left button
3. Add up all the numbers this is your unlock code. Example 26131=13
4. think right takes u back to TEST-NR 01
5. Press right till u get too TEST NR 20 then left
6. Get locked message hit left till u reach ur unlock code then right
7. Goto TEST NR-09 and hit left
You now see the 2 sender results live if your driving

Unlock only needed once stays unlocked unless you disconnect the battery. And hold right to come out of this menu else switch off and on brings you back.

Alot of folks reported wrong values and after a couple of fills it was fine and never happened. However they also mentioned they followed up by filling super.

If it's sender issue one of the sender has the fuel pump attached so more pricey other is just sender so cheaper but still BMW prices.

Hope that helps. As you can tell I had far too much experience here.

Cheers all, appreciate the responses.

I've been away on business for a couple of days and returned to find the needle and display reading somewhere close to the expected levels after a fill.

Wifey tells me it just started to act normally after about 25 miles, bizarre.

Anyway, I'm too busy to bother right now and while it's working I ain't gonna touch it guvnor......

Sounds normal

this was what alot of other folks mentioned after 1-2 fills everything was back to normal.

I think what happens is,very rarely the tank gets filled up which means the float on the sender rarely lifts to the max level. There then becomes a build up of residue on what is probably a pin that the float sits on thus preventing it to move. If that makes sense.
