Part 5: The Ultimate “Must-Have” A3 8V Coding Shortlist

If you only have 15 minutes, code these five crowd-favorites:

  1. Needle Sweep (Module 17, Byte 1 Bit 0) – Instant gratification.
  2. Alarm Chirp (Module 09, Adaptations) – No more guessing if locked.
  3. Scandinavian DRLs (Module 09, Byte 4 Bit 6+7) – Increases visibility & looks premium.
  4. Comfort Blinks to 5 (Module 09, Adaptations) – Enough for a safe lane change.
  5. Video in Motion (Module 5F, Byte 24) – Passenger entertainment on long trips.

9. Lighting examples (Leuchte sets) – 09

Each light channel has: Lasttyp, Lichtfunktion A–H, Dimmwert, Dimmdirection

Example – enable rear DRL (already in Scandinavia mode):

Leuchte23SL HLC10 → Lichtfunktion C 23 → Standlicht allgemein (Schlusslicht)
Dimmwert → 100

Fog as CH/LH:

Leuchte12NL LB45 → Lichtfunktion G 12 → Coming Home oder Leaving Home aktiv
Dimmwert AB 12 → 100

Typical coding tasks and example changes

Note: "byte X bit Y" means change bit Y in byte X (LSB=bit0). Tools show bytes in hex.

6. Body Control Module (J519)

Additional Information

Conclusion

This report provides a comprehensive list of coding options and configurations for various control units in the Audi A3 (8V). It is essential to consult the vehicle's documentation and manufacturer's guidelines before making any modifications or coding changes. Improper coding or modifications can lead to safety risks, void warranties, or cause damage to the vehicle.
