LEFT DRL LED (UU) flickering on Parking Light function.

[pedroanno]

Hello,

I´m having an issue with the DRL LED headlight that I bought for my golf mk7 tsi 2015. The Angel Eyes(Double UU) works just fine in all functions(low beam, high beam, daytime running light only), except when I rotate the dial to the parkng light position (::I><I:. The headlight is OEM chinese made and doesn´t have any brand name or manual.

It starts to blink when I switch to the parking light(how the symbol looks like ::I><I: , but only the LEFT SIDE (Right side if you look from the outside of the car).

I suspect that this has something to do with the factoryparking light function, which is single sided(left side).

Does anyone know what channel on VCDS do I have to look ang change???

I´m from Brazil and I couldn´t find this information in any brazilian website, so sorry for the grammar. : )

You will find the OEM halogen lights drop your DRL brightness down to 20% when you switch on position lights. This is what's most likely causing the flickering.

Refer to Don's explanations on Leutch programming, you will need to remove the settings that dims the DRL when position light is active.

That's the document.

I would tell you what channels to look at, but I'm out at the moment.

Basically, find the channel sets for your DRL lights, change the group for position light function to 100 brightness, and that should do the trick.

I'm still curious though...
This is factory feature for both sides of the drl, right? So the parking light position lower the brightness to 1/4 on both sides.
Why flicker on left drl only?

Well, LED drivers are very sensitive to voltage. The dimming action achieved for halogens would be achieved by lowering the voltage. Given the lights you bought were from China, who aren't exactly known for their quality workmanship/ products, it's possible the electronics between two sets of lights are just different enough for one to be problematic at lower voltage.

So the channels that I have to acess is:

4TFL LB4 and 5TFL RB32 ?

Correct.

You want to find the bank for position light function (Standlicht allgemein (Schlusslicht;
Positionslicht; Begrenzungslicht) )

And set the dimmwert channel for that bank to 100 for both lamps
