[Ovmsdev] VEHICLE_POLL_TYPE_READSCALING @ VWUP.OBD

[Michael Balzer]

Soko,

you misinterpreted the error response: 7F is just the general error
response type. The actual error code was 11 for all your attempts.

See Annex A.1: 0x11 = …

So you've got no luck, the device doesn't support ReadScaling.

Regards,
Michael
