03 mini cooper fuel gauge not reading
Hi, as title says I'm having some issues with fuel gauge on my mother's mini. I have read through online research and haven't came up with anything solid so I'm hoping someone can help me.
Fuel gauge is on the red led, range reads ---. I have done a dash reset, didn't help, I have stripped rear interior out to check the wires coming from the outside into the car and checked the earth connector there for corrosion, it's fine, pulled the covers off the tank and checked plug and wiring, ok.
When I use the dash test mode 6.0 is reading 08454, 6.1 is reading 00332 and 6.2 is reading --000 with a 3 for implausible signal.
Am at my whits end with this so any help is appreciated!
Thanks in advance
