Mercedes W203 auxiliary heating function

Hello,

I'm looking for the CAN commands to turn on the ventilation system when the auxiliary heater is activated. Does anyone have any idea where I can find these IDs? Unfortunately, I can't collect any data because I don't have access to a car with a parking heater.

Best regards, Jochen.

Could this module possibly be a solution for you?

Yes, that's exactly what I'm trying to replicate. The module costs an incomprehensibly high price. Inside, there's an Atmel microcontroller and an MCP device that sends 5 bytes of data to the CAN bus.

Yes, that thing is really expensive. I'm also looking for a DIY option.

Great if something is possible there.

Regards, FUK.
