Hi,

To my knowledge all fuel gauge sensors are electrically operated and are located inside the fuel tank operating with a flotation system. Based on this and on your description, it is possible that:
1. the electrical connection from the sensor to the gauge is open/cut (likely);
2. the sensor itself is defective (most likely); and/or
3. the flotation is stuck at the bottom reading fuel low (a possibility but would go with #2).

However, to my understanding there were some recalls specifically of erroneous fuel level readings, pls check here.

Further, you need to clear this up with your dealer or authorized BMW service as it is very likely that repair of the sensor would involve replacing the entire assembly; gas tank, fuel pump and sensors, as it would seem that they are all sealed together as one assembly.

ope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The fuel gauge is at 1/4 a tank when the car is idle but when we start it up it drops to empty. Is this a fuse or what and how can we tell how much gas is in the car?


The contacts in your fuel sending unit is probably worn. This can be expensive to replace. A cheaper way is to track your gallons by topping off your tank and setting your trip gauge to zero. Once your "low fuel" light comes on, take note of how many miles you have driven. Always reset your trip gauge at fill up and try to fill before the light comes on again (now that you know when it will light up). Good luck!

I filled my car the other day and the petrol gauge increased as normal. Now when I start the car the gauge gets stuck just above empty. I know there is no leak but I am now not going to know when I am...


Hi,
This will be 1 of 2 problems. 1. The fuel sender unit which is in the tank is faulty. 2. The fuel gauge itself is faulty.
Have these 2 items checked and let me know if you need more information.
Thanks

After filling fuel tank,engine light is on and gauge reads empty ,will it be a problem to drive, or should this be replace soon.


{: ) As long as your vehicle can start and run, you can drive it safely. However, your gauge wont tell you hown much fuel for the remaining trip. So better have it fixed before you ran out of fuel on the road.

Petrol gauge was working fine before a 5 week holiday. Car not used during this time. Now petrol gauge shows tank empty, even after I had filled the tank. What is wrong? How do you fix this?


sounds like the float is either got a hole in it and is full of fuel, or the whole float assembly is seized in the empty position.
was the car left for 5 weeks empty of fuel?

FUEL GAUGE AND LIGHT STAYS ON NEARLY EMPTY AFTER PUTTTING IN PETROL.WHATS THE MOST LIKLY FAULT. DODGY GAUGE OR FLOAT IN PETROL TANK.THANKS FLYNN.


Do you mean that the gauge registers as empty, even after the tank is filled? Probably the sending unit needs to be replaced (it's in the tank, likely partially attached to the fuel pump).

Faulty petrol gauge


I had same problem with petrol gauge bouncing around all over the place, full tank, half a tank and nearly empty in the space of 10 miles.

I knew that if I filled the tank I would get approx 200 miles for half a tank so I did that for a while and just kept topping up. Audi testing it and the fuel sensors in the tank had to be replaced. I'm afraid its the only permanent solution!
