Hi, long time member, first ever post. 
 

my ‘22 Kodiaq Sportline has developed an issue with the led matrix headlights. 
a few weeks ago the right hand side headlight stopped working. The following day it was fine but I booked it into my local dealer anyway. They checked it over and carried out diagnostics but found nothing in the history. 
today both headlights stopped working. They’re working fine again.  
I’ll book it in again but just wondered if anyone else has had this problem. 

I don't own one, but I will say I highly doubt they could not find anything in history for the faults.  My older car moans about a faulty rear tailight bulb and logs the fault in diagnostics.

More than likely there was a fault, but they couldn't fault the car on the day, so cleared and sent you on the way so that it becomes permanent... just what you want on a dark night.

I had the message for the driver's side headlight that appeared to be down to dirt on the exterior due to a particularly salty and slushy trip.  Cleaned the headlight, stopped and restarted the car and it hasn't re-occur over the last 6 weeks.  My car doesn't have headlight washers.  As far as I could tell the light was still on however the matrix smarts wouldn't work and I guess there's some part of the system that tries to make sure you'll not blind oncoming drivers if light isn't going where it's supposed to?

Its a camera in the windscreen by the rear view mirror. Having had Matrix lights on my Golf GTI I'm a little disappointed by the Skodas, they seem to be a bit clunky rather than smooth when they relight after a car has gone past

That's quite clever then, if the camera can see what's being illuminated by the headlights and throw an error if it looks 'off'.  Given the vast array of what might be getting illuminated, how would it even know what 'off' looks like.  Clever.

No... the camera is what senses the oncoming headlights and adjusts the beam pattern appropriately. If it is impaired, then it can't do that and the matrix functionality won't work. I don't think it detects what is being illuminated and knows if that's correct or not.

My experience was cleaning the headlight made a difference rather than the windscreen mounted camera.  Unless it's was pure coincidence and there's some sort of electronic glitching at play?  ...which probably sounds more likely. 😞

I get a dual lights fault showing most mornings when driving up to our local ski field. The lights aren't even turned on. Not sure if its angle of the car, temperature or the sun strike on the camera.

Clears when I park the car and restart it. Never had it show at night or any other time, matrix function works well otherwise.
