Hello together, can someone tell me how the above message is composed? On Wikipedia it is only stated that it is 4 bytes. In a Mercedes forum it was listed that there were. In another document it was written that gear + gear ratio are transmitted. Otherwise I found absolutely nothing about it clear, does not seem to be a really standardized OBD2 message, however some apps support this (e.g. CarScan). The technical prerequisite in the form of a self-made adapter is already taken. Only the gear is missing! Bzw. no matter what I have transmitted to the app so far, there was either nothing ” – ” or permanently ” 0 ” displayed. PS: Unfortunately I can’t look at my golf, because this does not support the PID. Maybe someone knows that, or can just check it out with 01 A4 Thank you very much!
