CraigW: Sounds like a dodgy lamp to me. They should all be glowing. Thankfully though, these LED bulbs are about 1/10 of the price they were when they first came out and I was fitting them to my Scirocco.
Just had Chris round. Tried out the tank contents remaining VCDS tweak which seemed to take fine but wasn't present when we looked for it in the MFD or even selectable to make active in the car set up menus. Chris' low fuel warning was on at the time, so we wondered whether that would stop the tank contents display from happening.
Just after, my broadband seemed to give up the ghost, given the range (we weren't parked right outside my house), so didn't do anything else. We did fit my unopened pack of Nightbreaker H7s to the static cornering lights. The bulbs already in were a b'stard to pull out, and the new ones were tough to go back in fully until we realised that the cutout tab of the bulb fitting should be facing upwards and not downwards (as I thought it was after seeing a springclip towards the bottom of the lightbulb housing). I now have an LED bulb in my boot too thanks to Chris.
Tuning box tomorrow!
