Problem solved.

Software 30790219 loaded to CEM with vida, not to AEM.

Call start of parking heater changed and now I can start fuel heater with grounding pin 3. I use eberspächer remote controller.

I have made support ticket a few months ago.

I have two AEM modules, other is from a car that has a working remote control. Both boxes send can commands when I ground pin 3. I think problem is CEM is not configured to listen that remote control command.

Volvo has advertized that package to all p1 cars

Thanks but there is only three options. I think Vdash people should activate that feature.

Additional with timer

Hello

Looking for remote start of the fuel heater my car has.

My heater has a timer function and works as it should. It also has AEM module and what I have read grounding pin 3 from Aem start the heater.

Only problem is how to enable
"call start of parking heater function"
I have not found that from vdash. I have flat subscription and pin code available. Picture is from vida.
