Njn, UDS protokol v budíkách může být nepodporována verze SW a tudíž pešek a čekat na update VCDS, nebo napíchnout na ofiko ODIS. :)
2F UDS command means input / output test.
The respond has to be 6F. (always more than 0x40)
The 7F means error. The control module reject the command. Maybe uds security access missing or the command was sent in wrong session state.
