Good job!
A flat battery will probably not cause any CCU faults.
I always note and clear all codes, then operate all CCU knobs for a minute or so, then re-read faults.
I'd keep an eye on the rear fan, it has obviously not worked in any of the two speeds at one time in the past. I mostly see both code appear when the motor has stalled due to bad bearings, and blown the fuse.
Fault code Speed 1 fires if the rear fan low speed resistor is shot. I change 10-20 of these resistors per year.
It is not uncommon to see fault codes on the CCU fan. (Inside Sensor blower) The fan bearings and magnets wear out, and it will not start. A road bump may start it. However, I always advise to change the fan when the fault code appear. Be sure to be safely seated well when you hear the price. Part # 964 659 148 02. (about 300 euro)
The fan is imperative for the unit to be able to sample the cabin temperature.
Cheers,
Tore
