Écho !! 😜

Well done, and welcome! Now we need pictures!

Yes it is - the gun is consistent, the ammo is consistent (unless you keep changing it) and the scope is consistent (might be ‘out’, but will still be consistent). The shooter and the wind are the variables. That’s some claim - over what distance?

I’d start by running a single jump lead from the battery negative to a good earth point on the engine somewhere (starter if you can get in there) - see if the problem then goes away, indicating a poor earth as mentioned above. Not sure why...

Haven't experienced this in a LR, but had a similar issue with a Micra. The issue was a corroded earthing point and partly ruined wiring. Check wiring, check earth points and check if it's charging, like JD said.

Don't see why not if access is good.

I’ve also found a Dremel with a flex-head and cutting disc to be very helpful with bolt removal in tighter spaces

I'd get yourself a ODBII code scanner and read the codes. It'll tell you why it went into reduced power mode.

How can people let their vehicles get like this… 🤨 That really does deserve some TLC now, and put back on the road with new shiny bits. It’ll love you for years.

OK it's official. Don't think vehicle has had an inlet clean, egr clean, oil change or filter change or air filter since it left LR all shiny new !! Have a look at these. The oil filter just fell apart. Wonder why it was overfuelling a bit...

Oh, I agree. Did my subframe myself last year. Just wondering what the OP failed on…

Well I doubt you’ll get £900 from a scrapyard. As others have said, why has it failed… rear subframe?

What's the garage telling you? What's so unfixable that it'll never pass an MOT. My FL2 is a 2007 model. It goes in for an MOT, if it fails (okay, when), I fix whatever is necessary and it passes.

Checked the fuse for the rain sensor? (F1 in the passenger side foot well)

Has it had a replacement screen fitted since it packed up? There is a module in the steering column for the wheel switches, but if other stalks/buttons are working, doubt it’s that.
