Lighting Software Issue

[Carole_Heard]

I have a nearly new C3 Picasso Exclusive EGS6 model with everything except the Myway as extras.

I spotted a problem with the fog lights.

When the side lights are on, the fog lights respond to the fog light switch.

When the headlights are on, either activated manually or using the auto setting, the driver's side fog light is on permanently and only the passenger side lamp responds to the switch. When the fog lights are switched to off and then the headlights are turned off, the driver foglight remains on for a second, then turns off under control.

I took the vehicle in to Toomeys Basildon and tried to demonstrate the problem.

The lights worked properly.

 

I realised that I had only ever seen this problem at night, because that's when I want headlights (!) so waited for it to go dark and the problem re-appeared. It seems to be associated with the light sensor and is therefore a software problem.

 

Anyone else seen this, or has my car become possessed?

You may be right about it being a software problem. To see if it does it in daylight, covering the light sensor up may help - usually this is in the middle top of the windscreen. I assume this is the front foglights. It is normal they should only work when then engine is running and the lights are on, sidelights or headlights. To confuse things, on page 80 of your handbook it also says if using auto lighting, when this auto switches off, the sidelights and foglights remain on until switched off using the foglight switch.

 

On our C4 the foglights can be used as cornering lights, so if the lights are on and the steering is turned at low speed, the foglight at the side of the car in which it is being turned will come on until the steering wheel is straightened again. This is set via the radio menu button, configuration and vehicle parameters. You could see if this has been set on your car and then switch it off to see if it makes a difference - see page 84 of your handbook.

 

It may also be worthwhile having a look/joining on the Picasso forum and there is a link to it on the home page.
