Hello Everyone I'm Michal and I own a 2019 Audi S3 Limousine. I've searched the forum and haven't found an exact solution to my problem. Since the car is already 4 years old, the DLR lights have burned out slightly and their color has changed to yellowish. I would like to slightly increase the brightness of the DLR lights with the headlights on. At the moment there is a visible difference in the color of DLR - Matrix. Could someone help me to solve this problem? Below are screenshots with the status of Lichte2SL VLB10 / Lichte3SL VRB21 And some information from ODBeleven Control unit: 09 Central Electrics Active errors: 0 Inactive errors: 0 System description: BCM MQBAB M+ Software number: 5Q0937084DC Software version: 0273 Control unit number: 5Q0937084CF Control unit version: H38 Serial number: 01001910806586 ODX name: EV_BCMMQB ODX version: 019001

hmm.........no offense intended - but I don't think so!!!
Those 2 x Leuchte-sets in your post don't contain commands that operate DRLs.
What type of Headlight lamps are installed in this CAR? If incandescent/halogen, then post-up pictures of Leuchte4TFL LB4 and Leuchte5 TFL RB32. If HID, or LED, then does this car have Light Control Modules (LCMs) - look at the SCAN report?

Thanks for the reply. It is a pity that nothing can be done.
The headlights are LED - Matrix.
Below is the data on the control units for the lights.

Ok. Thanks for your time. Tell me, from your experience, is it normal for the DLR LED lighting to burn out slightly after four years of use and change color from bright white to white with a tinge of yellow?. I don't know if this is a suggestion or if this is really the case.

misg : hmm.......if this is the problem that I'm thinking-of - then yes, this is a known problem!!
The problem happens because the the upper/lower DRL light-strips in the headlight fittings are really solid-plastic light-tubes which have LEDs physically connected to one end. The LEDs inject light into the light-tube and the light-tubes distribute the LED light along the upper and lower edges of the headlight housing. Unfortunately over-time, heat from the LEDs melts the end of the plastic light-tubes where the two physically meet. Discoloring from the melted plastic at the LED injection face causes the DRL light to dim - hence the reduced illumination.
As I have suggested to others - if this was my Audi and given that this is a known manufacturing problem - I would approach Audi for a replacement headlight fittings (regardless of whether the car is still under warranty). Of course, this depends on the strength of consumer rights in your country
Or you could handle this problem as a DIY matter like this (I suggest that you don't): Don
