I was going to email some pictures taken by me to watchdog tonight, showing the exact same damage as you seen on the corsa but in a fiat punto. Why are they limiting this publicity of fires to the corsa when the punto suffers the same problem with the melted wiring loom?
the dodgy loom he showed covered in black tape is available as a genuine Vauxhall spare because these melted connectors is a big issue! Last one I done failed exactly a year later. I then replaced it with a modified wiring loom which has solved the problem.
