Programming procedures
What the job needs
- Add a key: 1 existing working key required.
- All keys lost: no existing working key needed.
- PIN / security code: Audi Erwin / dealer ticket.
- Online / server access: required — None.
- On-board (no tool) sequence: not available — Audi B9 / MLB Evo (A4/A5/A6/A7/A8/Q5/Q7/Q8 2017+) is newer MQB-derivative with stricter security. Add Key/AKL requires Audi ONLINE security access (factory scan tool flow). Xhorse VVDI Key Tool Plus + ACDP module pair or Autel IM608 II with Audi MLB Evo package may work for some 2017-2020 builds. Newest builds (2021+) often require dealer with Audi VIN-bound security ticket. Confirm coverage with tool vendor before quoting.
- On site: engine off.
- Bring: Photo ID + vehicle registration. Title strongly recommended for AKL.

Notes & cautions
- This chassis (Q7 4M, 2017-2026) spans MLB Evo era with multiple facelifts (2020, 2024) — pre-facelift (2017-2019) typically allows IM608 II + XP400 Pro + APB112 OBD cluster dump; 2020+ MY adds incremental SFD/SFD2 protection. Verify facelift + SFD2 status by VIN.
- Battery support recommended for VAG MQB session (cluster data dump takes time).
- Audi B9 / MLB Evo (2017+): can require dealer-only ONLINE security ticket for newest builds. Verify Autel/Xhorse coverage for the exact VIN before scheduling.
- AKL erases all existing key registrations — bring minimum 2 new key blanks (XSMA1EN or compatible MQB-prepared blank).
Lockout
Door pick / decode: Lishi HU66 (CW).
