Do you have antenna on the boot?

Based on your picture of where the recess is it seems that antenna is directly above it and what we see is water damage from poor antenna seal dripping directly on the unit.

On picture of damaged plug I also see sound deadening material of what seems to be central locking pump. Are we sure there is no water ingress there?

No aerial at all on the car. Probably explains the c*ap reception on the radio. I pulled the alarm apart, and it was definitely caused by the two big button batteries leaking, which someone suggested.

It's in the rear window think it uses the demist wires and is why the FL rear screen looks like it's come out of the 70's and the PF is almost completely clear.

Thanks! I will open my box next time I get there and change those button batteries preventively.

The alarm horn is a sealed unit. Since mine was kaput, it didn't matter how I pulled it apart. It you plan on replacing the batteries, you're going to need something like a dremel to cut it apart where it was stuck together.

Thanks. Will attack with a dremel !

Added some info on the first post on how to get the alarm to 'blip' when locking.

My PF rear screen was equally riddled with wires as well as the "twirly" fixed aerial. But it did have the "full monty" of TV, LW/MW/FM radio, GSM and phone.
