Hi guys,

I removed my bumper today to replace my headlight due to a dead DRL, and after putting it all together I'm getting a load of faults show up. From the top of my head it's stuff like parking sensors, tyre pressure monitoring system, auto headlights, the external temperature sensor and all that sort of stuff.

I'm guessing I've probably not plugged one of the cables back in fully, but before I strip it all down in the morning does anyone know what set of cables they're likely to be? From what I remember there was about 4/5 small clips and one big one.

Cheers in advance
 
Maybe a short circuit occurred and you've blown some fuses? Is the new headlight a genuine VAG item or an aftermarket one?

Ok, so one of the plugs weren't connected correctly, so now most of my faults have cleared since I seen this.

I've had it scanned for the last fault and it's throwing C11C013 up. Fella at the garage said it wouldn't let him reset via his diagnostic.

Took it to someone I know and he said it seems like a loose connection with it saying open circuit, so off comes the bumper again, and everything is all connected nice and tight.

Has anyone got any idea where to take it from here before I pull my hair out? I can't get into seat for 2 weeks, and I have driving tests going out in it early next week 🙃
