Qball-18

Hi
I got a mk3 mondy tdci on an 2002 plate. Recently I've gone to start it but I'm getting the ignition lights but nothing after turning the key and the temperature display just has lines.

Normally a quick lock and unlock worked it but now it's not doing nothing.

I had a new battery on it 6weeks ago but I've just noticed that I turned the lights on and it's starts weirdly. I had no ignition lights other than the oil and air bag aswell before I turned the lights on.

Any ideas?

I found 2 fault codes on my bluefin reader that was p1246 and p1631 but no idea how to combat these...

HELP!!!!!
