Hello Adam

 

Welcome to the forum

 

Re: your fog lights, I dont mean to sound rude, but have you switched them on correctly ? http://www.citroen-owners-club.co.uk/citroen/topic/7130-rear-fog-lights/

 

Its an easy mistake top make if they have never been use before

Does the car have a towbar since some sockets have a fog light cut off switch ? This is a plunger in the socket which is pushed in as the trailer plug is connected. the plunger can get stuck and the connection at the back of it can get dirty/corroded.

Check the fuses and relay

[paul.h]

I had a look at the fuse lists in a 2008 C8 handbook and it does not list one for the rear fog lights. So if it is a fuse it would have to be a maxi fuse but then it would likely also affect other things.

 

If the C8 is wired similar to the C5 shown in the C5 Haynes manual, then the rear fog lights have a relay in the bsi dash fuse box and I think these are not able to be replaced easily. If the switch is being used correctly and it does not have a towbar, then it could be the relay, wiring or possibly the switch. If the switch, then this is part of the comms 2000 switch unit under the steering wheel so the complete unit may need replacing.

Just a quick word of warning which you are propbably already aware of - Can Bus systems do not like to have a 12 volt probe shoved into them.

Hi all thanks for all the replies :)

 

I have checked that i am switching them on correctly so thats not a problem.

I have checked the buls and checked all fuses in the car, all in the battery compartment, in the engine compartment and under the dash but all are ok.

 

I have no other issues ao thinking that it wouldn't be a relay as i cant find anything that is just for the fog lights themselves. The car hasn't had a tow bar ftted and i checked all connections and cables i can find but nothing...

 

I have no other issues on the control stick but as it doesn't have front fogs its hard to rule out that it isn't this switch that is broken.
