Notes & cautions
- This chassis (Porsche Taycan Y1A, 2020-2025) spans the Porsche J1 EV platform shared with Audi e-tron GT F8 — uses VAG MLB Evo IMMO architecture but with Porsche-specific security ticket flow. Autel IM608 II + XP400 Pro + APB112 may complete early Y1A builds via OBD; SFD2-equivalent Porsche security from 2023+ often requires dealer PIWIS ticket. Verify SFD2 status before quoting.
- Online security ticket may be required for 2018+ MLB Evo models.
- Newest Porsche (Cayenne 9YA/9YB, 911 992, Taycan/Macan EV, 2019+) can require dealer-bound Porsche PIWIS security ticket — narrow aftermarket coverage.
- AKL erases existing keys — bring minimum 2 new Porsche smart key blanks.
- Porsche Taycan EV: 12V battery support critical. narrow aftermarket coverage.
