Adaptations fail on Module 18, Aux. Heater. (Webasto Thermo Top Evo)

As per "screenshots" below.

Module accepts security code 20103 (verified that doesn't accept "wrong" code).
Tried a few different adaptation channels with same results.
Tried adaptation value above and below set value to eliminate hitting possibly min/max limit.
Tried also on another similar van with same results.
