No, the locking does not make any difference.
Nice, a good new at the end
My guess: it works=runs the heater but doesn't turn on cabin blower, however I think it might trigger a fault code (I think it has been a kind of "verified" somewhere in the Forum).
i think the cabin warming could be disable here, setting bit 3 to 0 but... i think the blower will still working...
in this post,
@Jey says the engine was getting warm but he does not specify if the cabin did as well with the config he had
@nuttygt4 sounds like you are going off on a bit of a tangent here to the original purpose of the thread ? If i understand it correctly you have the engine heater and want to change it over to be a parking heater and feed the cab, to my knowledge regardless of the overhead unit you need to flash...

same for MrJJ which shows this little resume
okay it is not about bits, it is just numbers. From VCDS forum found out:
00?xxx2: Axiliary Functions
0 = Start-Stop not active/installed
2 = Start-Stop is active/installed
00x?xx2: Remote Control
0 = Remote Control/Telestart not installed
1 = Remote Control/Telestart is installed
00xx?x2: 2/3-valve
0 = ENGINE & CABIN => to be verified
2 = ENGINE => to be verified
3 = CABIN => VERIFIED, FACTORY DEFAULT
00xxx?2: HVAC Type:
0 = Just Heating
2 = A/C with Climatic type controls
3 = A/C with Climatronic type controls
but i think this is from a T5. If the bit 2 and 3 = 2, that would mean bit2=1 and bit3=0 .... wouldnt it?
Thanks
@mmi again for your huge support
Cheers
