Hi,

Pardon me in advance if this is an oversight on my own part, because I bought my 2011 508 saloon car fairly used and unfortunately it didn't come along with its user manual.

I recently, took the car to a mechanic for a minor repair. Then I letter discovered that the low beam light is always on and the switches and low light ambient lightening in the vehicle are permanently on, even during a sunny day time.

I have tried deactivating and activating the automatic headlight several times without any success. I will really appreciate it if anyone can assist me with this issue.

Hi...can you turn the lights off at all on the stalk?

Yes I can turn it completely off from the stalk, but when the automatic headlighting is switched on, the low beam stays permanently on even when it's a bright sunny day.

Is the rain/light sensor plugged in?

Thank you for the prompt response. Where or How can I check if the rain/light sensor plugged in?

It's a sensor underneath the black plastic below the interior rear view mirror. Has anything been disturbed in that area?

HI...were the light working ok before the repair.....you could also try a bsi reset...if not sure about that have a search on the form.....(it may not help..but worth a try)

What was that minor repair? To me it looks like light sensor is faulty.

Sorry I didn't respond to you earlier. It was already night fall as at the time I saw your response, so I wasn't able to tryout your suggestion. I'll have to do that when the day breaks. To answer your question, actually yes. About a while ago, the windshield was replaced. Although after the replacement, the automatic headlighting was working OK. This problem started about a week ago, after I had the turbo replaced which made me think it was a minor settings issue. But after a lot of fiddling around I realized it might be something more than a minor settings issue, so I started surfing the web for answers and I came across this forum.

Yes! They were working OK, before the repair. I had the turbo replaced and that was an engine problem. Which I assume has nothing to do with the headlights. Before then, I had the windshield replaced. But the automatic headlighting was working OK after that repair. Although I'm yet to tryout @drdino's suggestion. Hence, I will let you guys know the outcome. I shall also try your own suggestion as well and I will let you know how it goes. Thanks by the way for the assistance and prompt responses. I really appreciate it!

I had the turbo replaced. I will check the light sensor when the day breaks. But wouldn't the car diagnostics pick a faulty sensor problem? At the moment, none of the OBD computers I have tried so far are showing any error codes relating to the light sensor.

In some cases there won't be any fault. You have to read parameters and see value for light brightness.
