Me again.
Reverse lights don’t work. Checked the bulbs and the fuse by the drivers pedal, all seem fine.
So I assume it’s the reverse switch. I’ve bought a spare and tried to swap it today. What a pain that is! I failed.
So I have two questions:
Is this possible without dropping the gearbox?
I wanted to test it was definitely the switch before I went crazy getting it out, so unplugged the old one and plugged the new one in, put car in reverse and switched on ignition and then pressed the end of the switch in but it still didn’t turn the lights on. Does the switch work this way? That you can push the plunger end in and it should turn on?

Not off a Z hence why I thought I'd post here.
It's off a 92 peugeot 205 1.8 diesel.
Done some research online and the consensus seems to be that the best way to test a coolant sensor is to measure the resistance with a multimeter.
Video of soime chap doing it here:
From what I can make out, I should be testing the resistance across the two pins on the back of the sensor.
When I took the sensor out the car and did this I got no result, zip. Aha I thought it's bust! Bought a new one but that does the same :blink:
After poking around a bit I found I can get a measurement if I touch one of the pins and the brass casing.
Does this sound right or are both my sensors bust?
When my multimeter leads are not in contact with anything they show the same as the top pic e.g. '1'
