Yes, got next day delivery from https://www.partsinmotion.co.uk/car-parts
Supposedly 2 different ones for the 24v vr6.

It was just so I could replace if any needed splitting, 
I found the sizes on LLL parts, and bought 10 febi replacements.
M10x1.5 if anyone needs it.

A broken abs sensor causes faults on the level sensor, I think it's all on the same circuit. I had the same when my rear wheel bearing broke the abs sensor.

You need to run a switched live from the fusebox to the aftermarket wiring loom, the standard radio wiring doesn't have the switched 12 volts to turn on when you turn the ignition on.
As for the esp fault, Its a main control failure I think. Quite possibly a shorted wire when pulling the radio out.

You can actually replace the handle, or wrap cable tie on it, Is there a key on it where it will only go in one way?
I replaced my interior handle when the lock buttons wore away but can't remember if it's keyed,
