Pulled these out of the IHKA error console....the heat exchanger temp stays low, but in high revs will climb rapidly, and then return back to cold pretty quickly....these leads me to believe there is air in the system.

1. AUC Sensor
Open Circuit, error present
2. AUC Heating
Short circuit to ground, error present



I also can't figure out the error with "Heat exchanger rated temperature"

Also, are those error codes normal?
