Purpose: to activate LED facelift taillights for Audi A3 8P Sportback (5-door) after phase 1 halogen headlights have been retrofitted with LED facelift.
Procedure:
1 – Engine off, ignition off, connect your official VAG-COM VCDS cable to the computer, then plug the other end into your vehicle’s diagnostics socket.
2 – Switch on the ignition and run the VCDS program.
Line 1 :
3 – Click on“Select”, then click on“09 – Cent. Elect.”.
4 – Click on“Coding 07”.
5 – Select the “0” module and click on “Long Coding Helper”:
- Byte 09 on HEX 00
- Byte 10 on HEX 00
- Byte 12 on HEX 36
- Byte 19 6th binary digit at 0
- Byte 21 Binary 4th digit to 1 (option see description)
Description:
- Byte 09 deactivates the variation of the brake light as a tail light. (This means that only the LED strip lights up when the parking lights and low beam are switched on).
- Byte 12 is used to adjust the brightness of the LED strip of the outdoor lights exactly to that of the indoor lights (at least if a Kufatec adapter with a 100 ohm resistor is installed).
- Byte 19 deactivates cold diagnosis of the position lamps. This means that the LED strip does not flash when the ignition is switched on.
- Byte 21 means that the rear fog lights are also activated during braking (so it’s purely visual, you have to decide for yourself if it’s important to you!).
