Might be a daft question

[MVRH]

As above Caddy 1.6TDI PCR 2.1

Apparently mapped before and unlocked BUT ECU intact

Kess ID says locked

So can this Ecu relock itself after unlock its not had NOX update

Thanks

Impossible,
Read with VCP and check ecu status

I thought as much just wanted to clarify with others. Thanks

it was unlocked via OBD and after remap ecu was locked back.
