hi all,

i have a strange fault with a 2015 audi a3 2.0tdi fuel gauge.

9453074 - Fuel Level Sensor 1
          B103E 1B [00001001] - Resistance Too High


wiring has been checked and sender unit replaced. 

we decided that it must be the cluster at fault, so we got a used replacement and programmed it to the car with odis,   fuel gauge all working fine now with no dtc's.

we locked the car and packed tools away, job done we thought.      when we started the car the fuel gauge error was back.   :headbang:

now this is the strange part,     i can start the car and disconnect the cluster while its still running and then reconnect the cluster and the fuel gauge is working and i can clear the fault code.     i can now turn the ignition off and on as many times as i like and the fuel gauge will continue to work with no dtc's,  but if i leave the cluster to shut down with ignition off the fuel gauge will not work when i turn back on.   at this point i need to start the car and disconnect and reconnect the cluster for fuel gauge to work again.


i have checked the coding of the cluster is correct and everything looks ok there.

i can not find any tpi regarding this issue either.


can anyone help with this one please.

thanks
