Interior light / headlight warning buzzer

[Greem]

This is the exact same problem I have, which I wrote in this thread:

MK3.75 driver's door light switch wiring

I’m not sure what you mean by “server” here. I still haven’t traced the problem. I’ve had the trim off the windscreen and followed the loom but can’t see where the wiring goes - at least part of it goes to the ECU and/or alarm system. Fairly good shout on a corroded contact, if only I could find it!

I’m glad it’s not just me.
