Audi A6 4G Engine CAN IDs?

Hello,

Can anyone tell me where I can find data for all temperatures, boost pressure, torque, and ignition timing within the engine's CAN bus?

Regards,
Jackson.

Hello Jackson,

Not everything is necessarily sent via CAN. A lot of information about the diagnosis can be retrieved via the diagnostic connector.
You can easily find that out with VCDS.

Temperatures are very difficult to work with because you don't know what offset and scaling factor they have.

I have an ESP32 with CAN functionality connected to my A4, which retrieves approximately 20 data points via the diagnostic interface. These data points can be displayed on the screen, and every 50 kilometers, they are saved to an SD card.

Torque, fan, speed (RPM), speed, DPF values, levels, temperatures (quite inaccurate).

Best regards, Uli.
