Heating control automatically sets both sides to full heating
Although the display on the control unit is different.

With the Tech2 the servos are controllable.

Functions such as

-fan control (also automatically),
-rear window heating
works without errors.

Recirculation does not work;
After pushing the orange light flashes - no reaction on the servomotor


Error codes B0229, B0408, B0418, and an old error code B0414
Also with the Tech2 not delete.

Air flaps are easy to move,
Servomotor exchanged for new ones;
Cable (wiring) tested for continuity
Voltages at the plug-in connections.
Replace the HVAC control element with a new one

Can it be that the system for safety on heating is caused by a special error?
Are there additional control messages from the BCM? - could the error be there?
