Audi A4 B8 Speedometer Calibration ID

Good evening.

"I'm working on a motor swap using a MED17 engine control unit from an A4 B8, and I'm missing the speed signal to the ECU. According to VCDS, there are two speed signals within the ECU: one for the wheel sensors and another for the vehicle speed. Since my ABS system is an older generation and not compatible, I've routed the signals for both the wheel sensors and the vehicle speed to my AIM MXG speedometer on a separate CAN bus, where they are also displayed."

I now need to send these speed signals to the drive's CAN bus, but so far I haven't been able to find the correct IDs because I don't have a suitable car to log data from. Does anyone have any information about that?

Best regards,

Hello,

You have a private message (PM). You can check the function description to see which signal comes from which CAN ID.
