I feel this is going to be a long drawn out affair so I'm looking for an auto electrician who knows their way around these cars, does anyone know of any around the Glasgow area?

Is this still the CANBUS issue from last summer?

Have dealt with a few of them since then, and they have always been at the back end of the car, the wiring to the (non-existent locking rear diff.

Wires are traced, and joined inside the car, doing away with the RDCM wiring (assuming thats what it is)

Aye,
Thought the stealers had sorted it but no.
They did check the wheel arches and all the connector plugs and ended up sending a tech request to LR

Of course. But flat out until May now, so as long as you are not desperate...

Ok, I'll be back after 14th May so pencil me in any time after then  2.7 HSE, Audi A6 Exec, Honda Accord Exec, Volvo 440, Volvo 360
