A Plug/Pin has melted - what's it called?

[TeaTimeGilly]

:( Hi

Passat (Estate - TDi 1.9 - Year: 2004)

The plug unit that sits adjacent to the bonnet lock, at the top of the radiator housing HAS MELTED.

There are two small pins/connectors (about 5mm in length).

You can still unplug the pins - and plug back in, but the plastic has melted.

Does anyone know what this plug is called - and if at all possible what it's function is?

I will be posting other problems that might be related to this - i.e.;

Intermittent fault which cuts the engine dead.

Thanks in advance.

That is the bonnet switch but why has it melted? I have never seen that happen.

These switch at Earth don't they? If so it must be shorting to a live somewhere. :confused:

Yes it is and the output goes to the convenience unit and the dash.

That sounds like a big can of worms could open. :(
