Early in my ownership of the car, I had a major melt down of the wiring loom that runs along the front left side inner mudguard, (inner wing to you Pomgolians) to the front lights. I repaired the damaged section of wiring loom, but I never found the exact cause, obviously somewhere in there a short had occurred but as it was burned to a crisp, I couldn’t tell where.
It’s possible that it might just have been a shitty loom.
