A/C ERROR - IHKA PROBLEMS

523 Views 8 Replies 2 Participants Last post by  TheBMWguy98
Good evening guys, I'm going crazy to remove the error:

FF [ 255 ] Energy saving mode active.

It is active in the IHKA module and the air conditioning and rear window defogger do not work.
I tried to access INPA but I can't deactivate this mode.
anyone can help me?
Unfortunately none of the threads is clear and resolutive.
Best regards

Looks like Transport Mode got turned on.

This video shows turning it off in the Radio module using INPA.

This video shows turning it off in the IHKA module using DIS.

Yes, how you do to disable?

It is not the same mode of transport.
In this video you shared it's about the mode of transport for the radio.
I have the error code "255 energy transport mode" in module air conditioner.

See my edited post above for IHKA. Although he uses DIS, I expect INPA supports it.
@Bali DIS and INPA are not the same thing..
I only have INPA and NCS Expert
Doesn't anyone know a solution?
Good evening everyone, after various checks with Inpa, NCSexpert and Toll32,
I have confirmation that it has not gone into transport mode but there is an error present.

I have a short circuit to ground of the a/c system and I'm trying to solve it but I also encountered a potential problem with the IHKA module because if I activate only the fan the speed never reaches the maximum but halfway, the A/C button doesn't work finally it rear window defroster (see video).
I have a strong suspicion that it's the completely broken the resistor, is that possible? :unsure::unsure:
