  • ✔️【Important: Two Different Connection Ports – Read Before Use】 To avoid “not working” issues, please note: For 1994–2000 BMWs (most E36, E34, Z3, early E39), the SRS diagnostic port is a round 20-pin connector under the hood. You MUST use the included 16-pin to 20-pin adapter cable. For 2000–2003 models (late E46, E39, X5), use the standard OBD-II port inside the cabin.
