fuel guage problem

[pvw10]

I was on here before which vanished, anybody know why ?

Anyway please advise if you can help, my fuel guage is stuck at half full. Guess a sendor/sensor has died or most likely a poor contact, if so where are they situated could you advise ?

Thanks

Reposted from the original thread, grats to Jeegnesh...

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.
