I had some problems with the activating of my reverse lights and then my reverse parking sensors and camera. I did some fault finding and found out it was the switch so I bought a new one decided to write it up as I couldn’t find much helpful on the topic.
I did this on an 09 plate 1.6 TDCI so might be different for other types
I used the following tools:
22mm double depth socket (and ratchet)
7mm socket + ratchet +extension
8mm rat ring (could use a small 8mm socket and ratchet)
first I used the 7mm to remove the cover of the air box (4 bolts)
then I removed the air filter and prepared to remove the air box
I then removed where the air box is connected to the engine by removing what im guessing is the air flow meter 8mm 2 bolts
now the elastic holding the air box down at the front needs to be removed
now this is detached the box will just pull out from the 2 rubber mounts and from the pipe at the front, it takes some wiggling, now you can see the switch
using a piece of wire you can confirm the switch is faulty and the rest of the circuit is ok.
as you can see you need a double depth to fit over the plug part
the 22mm socket just fits over the switch and I attached the ratchet and removed it, it becomes lose after just un nipping it
I could put my hand to the left of the battery so I was able to see what I was doing when putting the new switch in
now was just a case of testing and putting the air box back, whilst I had the air filter out I thought I might as well put a green cotton one on :)
