Discovery 4 fuel gauge problems

Baz 1960 · Apr 15, 2023

Bought a 2010 Disco 4 and thus started my tales of woe and expense..
The latest issue is fuel gauge with erratic readings..! To date 2 garages have had a go each day one telling me it’s fixed and s far to the tune of £1200 and the issue remains…
Does anyone have any suggestions, I hear the BCM could be an issue, do s you his have Amy control over h gauge readings…??
Thanks for any advice..

Was one of both fuel level sensors replaced at a point for those £1200? anyway, seems a quite complicated issue, here's what the WSM states for that symptom on a D4:

Used to be a common thing where rodents had got onto the top of the tank and eaten the wiring.

Presumably a £1200 repair would be from an LR dealer, so all the calibrations and tests would have been done.
If it wasn't an LR dealer, then it's possible that the job wasn't done correctly. Unfortunately on a modern vehicle, you can't just fit replacement parts, as they need calibration with the correct equipment.

Indeed might be the cluster as they can suffer with dry soldering joints, get them to double check that whilst hooked up to an oscilloscope

along with the rear near side connectors that sit on the chassis frame

Fingers crossed get it resolved as blimey £1200 and still having the issue, indeed sounds like a new garage is req

Well to close this expensive chapter, two garages couldn’t sort it, it’s now gone to we buy any car. 2010 Disco 4 for the princely dime of £4500, that 10k lost in 18mths plus repairs

Should have sold it privately for much more than the trade in price.

Not with the amount of other things wrong with it…!
