Hello,

I'm asking for your help because I've run out of ideas and am starting to lose hope...

Recently, I've been driving my Škoda more often at night, and I've been getting countless "flashes" from oncoming drivers. I decided to investigate the issue because the headlights were not lowering their beam when the boot was loaded.

Here is the situation:

1. The headlights perform their self-test when the car is started (right, left, down, up).

2. The headlight motor tests are completed without any problems – the motors move the light beams both up and down.

3. Basic Settings for the headlights have been performed, and there are no fault codes. The sensor reading is 46%.

4. When I load the boot, the sensor reading drops to 41%, when two people inside it is 42%, and go back to 46% when empty....

Unfortunately, the light beam moves upwards, and no downward correction takes place. :(

I'd also like to mention that the system was working correctly 6 years ago when I bought the car, and I was really impressed with it at the time.

Two years ago, I was involved in an accident. The car was repaired at an authorised Škoda service centre, and both headlights were replaced with brand-new genuine units.

Additionally, I've noticed that I cannot enable the DYNAMIC CORNERING LIGHTS option in the car's infotainment settings. It switches itself off again after a few seconds.

I would really appreciate any help, suggestions or advice you could offer. I'm running out of ideas and would be grateful for any pointers.

Thank you in advance!

So the crash repair is the most likely issue.

Might be a long coding issue which tends to tell the car which items are installed. If the car doesn’t think it has self-levelling headlights it might not be listening to any level sensor if that makes sense.

What’s the make model and year? And do you have DCC?

Skoda Superb 3 2016, i don't have DCC. Is it possible to do anything with that long coding with OBD11?

Mine is 2016, no DCC. Headlight part number ends in A. Corrector part number 7P6907357D. Long coding is 06DE00003F010000 if that helps at all.

Could it also be a faulty level sensor on the back axle? or would that give a fault code?

Sensor is working and change values after car is loaded. There is no fault code. Lights are working for sides, but no decrease the snop of light.

might be coding of controller. you should be able to see this with OBD11 and compare to mine. I have no idea if it will be directly applicable but could be a good place to start.

Only danger with quoting a full long code is that certain options or locations may differ between models. Many of the long codes quoted in the VCDS posts are different except for the pair of digits being changed. If that makes.

Yes. Advice from someone such as @Cairus might be required. He tends to know the long coding for everything!

Sensors may working yes, but was it fitted the right way round after the crash repair?

Cause the leveling sensor arms that pivot can b fitted the wrong way round, and cause the headlight aim to misbehave.

This how the 3x sensors on DCC equipped cars should look like this....

Front left axle

Front right axle

Rear left axle

OP doesn’t have DCC so it will just be the rear sensor. So should. Have been impacted in accident.
