Hey guys, newb here. I have an unusual thread that I am hoping someone with lots of knowledge can help me out with. I have an 06 Jetta TDI and Ia m building a simulator to test auxiliary air heaters on. I am close to having it running but I am missing a couple values and not sure where they come from on the car. The first one is the max heat value. It is the Climatic system and I know when you turn it to max heat, if all other parameters are met, the heater should turn on. I am not seeing this value change on VCDS. The other one I am looking for is the source of Terminal 30 voltage. I know it is battery voltage but what do I need to duplicate this signal? Is it from the ECM or another module found on the bus? Any help is appreciated, I know this one isn't for everybody. Just need one person with the answers. Cheers
