Hello everyone, I have a question. I have a 2009 Audi A3 vr6. I installed the ecumaster Black plug and Play,

After start I have 12.9 volt

Since the generator is running on Lin with the original control unit, Ecumaster only has Canbus, I cannot control it via the ecu master, Is there any solution for this?

The A3 8P Generator does not have LIN and you can not control it.

Pretty sure if you check the wiring diagrams it’s not lin bus
