I guess if I can find out why the terrain fault happens and fix it I'll not get the fuel gauge limp mode fault.
Looking at the prev history it's had a ecu change. I was a bit dubious of this as the garage bill was only £650 Inc a cam sensor. Maybe it's a dodgy ecu...

The term ECU does tend to get used for all the 'xCU's on a car and there are probably lots of xCUs on a F2 - maybe it wasn't the main Engine ECU. I agree that would be cheap for an Engine ECU - however, maybe LR covered the cost of parts? They have been known to sibsidise some parts (that should not fail on a young car) outside of the warranty period if people shout loud enough.

When you had diagnostics run, did they give you a print out of the fault codes?
I always think about bad earths when lots of unrelated faults occur together.
Sometimes I look sideways at a Freelander 2 for the wife, but having looked through those wiring diagrams I’m not so sure... They should come with a full diagnostic platform built into the glovebox. This weekend, I hoisted the back end of our F1 Td4 wth the telehandler and coated the underbody with rustproofer. The one before, it had a full service. I think we’ll hang onto it for now

How many of those were from fiddling/unplugging? It would be nice to clear them all and see what comes back.

We can’t ignore all those TPS faults. Unless you can scope the output for dead spots (multimeter might miss these), then how about swapping in a new one?

It’s located on the Haldex coupling by the rear diff
Auto electrician has spent a few hours on it going to change acc pedal 1st then poss get a 2nd hand terrain response module.
Maybe a new TPS after that we are into repairing BCM.....

Did he find a fault with the TPS? I guess not, but interesting to know anyway.
... And how did he test it?
Checked a lot of sensors.
The acc pedal actually had 2 12v supplies but when he took the pedal off we found breaker style writing on it so figured it was best to replace.
The terrain response module had a couple of cracked solder joints on the pub grounds.
He really flowed them but no difference however it may be a possible cause of the fault so I will source one.
Never tested TPS but it's making a very high pitched whistling noise, I just wonder if it's faulty....
When he turned up we started the car up and plugged in but it took 30 mins before the fault appeared.
Random......

*cough* lead-free solder *cough cough*
If you have some spare time it might be worth getting one of those cheap ebay hot air solder rework stations and some flux. You could reflow all the joints almost quicker than inspecting them. Some cracked solder joints aren’t even apparent under a 10X microscope, some need the component to be moved about.
