C5 X7 Lights

Post by hayden641946 »

Since buying my Citroen 2010 C5 3.0 HDi which I like very much , most of the time , my front lower driving lights have at times worked only one side , then none then the other side ???
Which I pulled the front off my car to work on the aircon condenser , I checked both bulbs and OK ! Since buying a LEXIA 3 from easydiagnistics , which I am still learning how to operate , I cannot find anything in the BMI to indicate a fault and still no lights . I have disconnected the battery to see if the system will reinitiate and still no good .
Next , check all fuses related , none blown !!!!!!

ANY IDEAS FROM owners of the same Citroen C5 Please ????

Thanks ,
Hayden

First of all can we be clear on which exact lights you are referring to?

1) You have directional Xenon headlamps. The DRL (Daytime Running Lights) are incorporated into the headlamp unit as marked in red and yellow:

2) Or are you referring to the fog lights:

or 3) are you referring to the Cornering Lighting shown below:

I suspect from your post that you may be referring to the angular / cornering lighting in the last picture and if this is correct, then the function you describe is normal behaviour. The cornering lighting operates when the headlamps are active and whist turning the steering wheel when stationary or at low speeds. They are designed to light up the corners of junctions or when going round twisty roads at low speeds. The left one operates when the steering wheel is turned left and the same for the right side when turned left, and the go off when the steering wheel is returned to the centre.

The lower fog lights incorporated into the indicator housing are simply fog lights that have to be activated manually and these operate with the main headlamps when you switch the fogs on.

Thanks Marc for clarifying a lot the lighting control with drgs and instructions . The fog lamps were what I thought , daytime running lamps !!!!
The running lamps have rever worked since I have owned the car .
I looked at the manual for light control and it didnt matter how I rotated B on the stalk , with headlights on , I could't get the front fog or rear fog lights to work ???
Any ideas ?

Ok

1) The legal requirement for DRLs in the UK for the build date of your car were not in place at that time but were in many European countries. So, Citroen shipped them in the UK market with the DRLs deactivated. It was the same with mine. If you have Diagbox, you can activate them via BSI configuration (caution advised) or get the dealer to activate them for you. Once they have been enabled in the BSI, this then activates the option in the menu on the dash, once you press the left-hand wheel button in (the car must have the ignition on or engine running and be stationary):

When accessing the Lighting menu, the DRL option will be present if they are activated in the BSI. You may want to try this first to see if the option is there - in which case they have been activated and you can just enable them here. Just scroll the same wheel and press to activate or deactivate an option.

2) Fog lights. These should be working fine. All you have to do is have the engine running, then activate the main headlamps. Then on the lighting stalk, there is an 'inner barrel' which you rotate once forward to activate rear fog lights, then a second forward rotation to activate the front ones. Repeat this in reverse to deactivate them:- roll the inner barrel back wards to turn off the front fogs, then again for the rear fogs.

Whenever the main headlamps are switched off (i.e. with engine off if the lights are set to AUTO), then the fog lights will also automatically be switched off.

If you don't have the owner's manual, and want a PDF copy, let me know.

Thanks Marc for your effort in helping me . I got into the system through Lexia 3 , then BSI , then repair and got a different screen to what you have shown for lighting . I looked everywhere so I just tried to configure what I could find , which was Presence of front fog lamps . I also configured Presence of four position lighting stalk .
Then configured fog lights using the two cogs . Started the engine and set rear which showed a green light on dash then front showing an orange light got out and both front and rear working perfectly !
There is nothing saying Daytime - running lamps or Guide - me - home lamps , only Presence of parking lamps , which I set to yes and configured but it did not make the Daytime - running lamps work ???? Any more ideas please ??????

Ok, some confusion here....

Be VERY careful what you change in the BSI - some options are not what they seem - and are for different vehicles (like Peugeot) that share the same BSI but have different systems for both displaying and communicating information displays and how they handle options which are dependent on the type of displays and dash and other equipment / options fitted. Some things may seem like they are incorrect, but are in fact correct for the C5 X7 and there is no 'undo' option, so whatever you do make a screen shot before you change anything so you can revert it back again. If you change even one thing not intended for the X7, you can cause the car to become unstable and exhibit weird behaviour.

The menu above in my screenshot is not from the Lexia - it is from the car's main dashboard LCD display in between the speedo and rev counter. That menu is accessible without needing Lexia at all.

The only reason you need Lexia is to enable that menu in the car's dash lighting menu for the DRL option to be there if it is not already. Please don't change any more options until you know what youa re doing Hayden, as you could be actually causing problems.

I will locate the correct options for DRLs now that I know you are at this stage.

In the meantime, may I suggest you have a read of my post here:

For Daytime Running Lights

In Diagbox, when you have gone into the configuration - manual configuration menu, look for the following option:
Type of daytime running lamps
The following option should be selected from the available choices: Dedicated daytime running lamps

Save that configuration, then back up and then locate the following section:

Lighting of the day running lamps by default
Select the following option Yes

After making that configuration, back up and locate the following:

Simultaneous lighting of the day running lamps and sidelamps
Configure this to No
Make the configuration change and then exit back out of the menus and close the session.

Switch the ignition off and leave it for a minute, then start the vehicle, and check the in-car dash menu activated by the press on the left hand steering wheel barrel scrolling button to activate the menu in my previous post, then go to the lighting menu. You should now see the option to activate or deactivate the DRLs.
