55 Pug 107 2-tronic fuel gauge shows full regardless

[piemanpete]

Hi Folks.

I suspect I know the answer to this already, but just in case it's a well-known 107 quirk:

The digital fuel gauge is stuck on full. My guess is that the sender is faulty. Presumably that's in the tank with the pump as a single assembly.

But maybe the display or its driver circuitry is to blame?

Anyone have any experience of this fault and likely/probable cause/s?

Any idea what I'm looking at cost-wise for a new sender/pump?

Can I see such a fault with a diagnostic computer?

Thanks in advance for help and suggestions.
