VW A/C Compressor

[muehlpower]

i did the same thing but it looks like the control message format for my compressor is a little bit diffrent so no change in the feedback message.

i will take another try at it or i will go tesla can controlled compressor.

thank you for your help on the heater it worked as you mentioned.

Have you tried to send all IDs filled with data and with different lengths with the right checksum?

I'm not sure what the pinout is yet Ideally would be looking to include this heater into the Zombie to expand the range of heaters available.

What is the power output of the DBK heaters by the way? Does not say on the label.

I found the LIN messages for the water heater. The feedback comes on ID48. Byte 0 is power. 13 for 770W, 26 for 1540W. ID28 is sent for control. Byte 0 is power, last bit of byte 1 starts and stops.

connectors are:
HVA 280 KEY_E from TE +HV near to the body, -HV far from the body
1J0973714 1= +12V , 2= GND, 4= LIN

Sorry a little of topic, but are you aware of any limitations on how this heater can be mounted? I'm looking to mount it horizontally flat.
I so far only found good illustration of these used in audi e-tron and they're mounted like this....

As an example. Tesla battery heater has mounting orientation limitation as well described by Lars here: https://www.evcreate.com/using-tesla-th ... y%20heater
