ECU FAMILY
MEVD17 — MEVD17
Definition
BMW-specific variant of MED17 (M-suffix for BMW). Used on N20, N55, N52 N (later years), and some F-chassis 4-cylinder turbo engines. Mechanically identical to MED17 — different software signature and a BMW-specific security access routine.
Why workshops care
BMW chip tuning on F30 320i / 328i / 428i runs through MEVD17. Same Stage 1/2/3 workflow as MED17.
