Just bought a Jetta 2.0 Diesel 140 sport. It was a crash damaged one with a small crack to the front bumper and headlight brackets snapped. Its Cat B but it was that minor i've kept the original bumper and the headlight wasn't even cracked just replaced it as the brackets were snapped.

Anyway the engine management light is on. I have done a scan on my PC and its coming up with:-

I'm thinking that its not individual problems and more that there might be a harness problem as they are all at the front of the engine. I have tracked it to behind the head light i have replaced on the nearside! There are 2 connections behind the light that i have cleaned, uncoupled and reconnected. There is an earthing point behind the light but cant see it without my torch so will check that later in the week, then it goes up behind the fuse box. I've checked the fuse box and fuse 24 had blown (10 Amp) so replaced this thinking it was going to be the problem but still the engine management light is on.

Anyone got any ideas except the ground behind the light? Also what Fuse 24 was for in the engine bay?

Thanks Brian
