3008 (2018) Check The Dipped Beam Headlights

MY3008 said:

Hello, So, we had a reasonably big 'bump' in our 2018 3008 Allure a month ago, basically damage to front bumper, and left side fog lamp. After a near three weeks in Accident Repair we have new bumper, fog lamp unit and reg plate and looks great (picked up on Friday just gone). I have been told it has been through quality control twice. Accident Repair Center pretty poor comms but thats another story. Yesterday was the first time we have driven in the dark and headlights (full LED) switched on. Within a few seconds of switching on we got a orange spanner, flashing green dipped headlight indicator and a service message stating "check the dipped beam headlights". The headlights both dipped, full beam as well as daytime running and indicators are physically working correctly, auto headlights come on and off correctly and cornering lights come on when expected. When I switch them off error goes away but after swiching back on error returns after the few seconds. There are no codes showing on OBD. Now as stated the ARC have not been great so far and I have stopped using my local Peugeot dealer (another long story). I do have an extended Peugeot Warranty and my local Citreon garage now look after me (not that they are particulary great either but better than the other two). Before I contact either on Monday I wanted to check if anyone could shed any thoughts on what could have gone wrong or things to try? Could this be due to the repair work or just a coincidental fault? I want to believe when the ARC rebuilt the front end they have just not plugged in a sensor or something, especially so as the actual lights all seem to be working. I also suspest the ARC will say its not us, it left them working and my garage will want to charge me for diagnostics, albeit Id try to push through warranty. Just want to be as prepared as possible for the likley fight ahead. Obviously if anyone has a quick win idea then please also send my way. Thank you in advance. View attachment 104911

Hi Keemon297,
So I took it back to ARC and spoke to the Workshop Manager. After a good few hours of further diagnostics and speaking to a lighting specialist they have come up with the following reason. On the headlamp unit (which I was unaware they had fully replaced due hidden damage) there are two significant parts. The front end that contains all the LED parts and a metal part that this sits into in the back of the this (he called it something but to be honest cannot recall what it was). It sort of looks like a heat sink. In fairness to the ARC they admitted they replaced the front part but not the rear metal part which they explained in all other brands would not need to be done. Apparently for Peugeots each part is coded to each other so both need swapped out together (he stated Peugeot are a nightmare for doing this apparently) but this was based on a lighting specialist they had to consult as heads were scratching at the workshop. He did say lights are all tested, working and calibrated correctly they are just not talking to the car from a comms perspective. So good news, car got booked back in and ARC provide courtesy car. Unfortunatley at time of pick up find out the parts sent are incorrect despite ARC assuring me they ordered correctly. So waiting until we are back from holiday for them to have a second go. I would love to think this will now be resolced quickly, mmmmm watch this space! In fairness to the ARC there was no challenge on whose fault this was, as I thought it may turn into a protracted battle between, ARC, me, my insurer and Peugeot Warranty. Hope you get yours resolved but definitely go back to ARC in the first instance. If you have a good relationship with your local dealer you could also seek their advice for free to pass onto the ARC (I did not have this in my case).
