So not much going on over the last few weeks, but finally sorted a few niggles.
Tonight sorted the headlight auto-leveling, details can be found here, turned out to be an easy fix

Also managed to learn the steering angle sensor so hopefully no more ESP light after 20 mins of driving.
Got one of the door blades off, rubbed down, couple of coats of primer and a couple of coats of Dolphin grey, will lacquer it tomorrow and see how it looks. They looked naff in dark grey.
The only codes remaining on my latest scan are the engine mounts and radio:
