Dynamic Light Assist

Just checked that second link, ah no. definitely pre 17.

Sorry, yes its on all the time and it dims them from main beam when a car drives past or you come up on street lights.

[kamold]

it just dims them from main beam.

What does the startup sequence for the headlights look like?
If it's DLA you see the lights sweep up and down then out and in with a definite mask visible in the middle.
Regular AFS sees light all across the frontal area.
Not sure if this makes sense...

Here is a video of DLA startup in slomoTapatalk Cloud - Downlaoad File VID_1510282960396.mp4

Yep, the start sequence does the dancing headlights. Sweep out, in, up and down.

But can you see the masking in the middle?
My 2009 car with AFS does the sweeps.
But it cannot mask like that.

If masking means the big gap of light in the middle when the lights sweep out, then no.

They definitely dip beam when approaching oncoming traffic though.

I can't code the CE module in VCDS, it's all done through adaptations.

Also, I can't see bit 6 on Byte 4 on the 55 - (headlight range) module either.

That's HBA high beam assist.
Not DLA.
You need the parameter set applied to your headlight range module.

That sounds like you've enabled HBA to me.

You will need to just manually change the bit.
Counting from right to left where the right hand side is bit 0 (if using vcds)

Ok, cool. That's what I was after.

Sorry bit of confusion with similar terms..
By masking I mean the dark spot which is being created on the centre of the beam pattern on startup.
The BCM has no coding, it's all masked as zeros.
All behaviour is controlled through adaptation channels.

Ok, yeah, looks like we can only get HBA to work without Kamold's parameters, and even then, we might not have the right headlights.

Kamold, I'll try and get under my bonnet tomorrow and note down the part codes of the physical headlight. It may help you work out which ones are high and which ones are not.

[DR074]

Just checked, definitely no light gap.

Sorry boys for the run around, just trying help. I've got so much cool stuff out of these forums. Thought I better try give back.

This is all brand new to me as I don't have a new Passat.
So your assistance has helped clarify the situation further

Thus far it looks like the Aus delivered LED Passats are all category 3 requiring parameter upload to complete the puzzle (if you count 2 from 2 as anything like a significant sample size lol).
