So, In NCS Expert, we probably just need to change the following in KOMBI module :

KUEHLMITTELTEMP_ADC_WERT: kennline_03

to:

KUEHLMITTELTEMP_ADC_WERT: kennline_04

And then change MOTOR_UEBERTEMP in LCM as noted

That would be simpler, BUT you should load the module trace file into NCS dummy to ensure your temp characteristics are the same for your Option 4 as His Option 4 are, just for piece of mind.

Yes that's what has to be done. But as Clockwork stated you have to check the values match, just in case. And for MOTOR_UEBERTEMP you will certainly need NCS Dummy, because you have to update the DATEN file with the new value 114c celsius. It's an easy to use tool.

Thanks all who detailed this mod. I finally did it today. And I checked with test 7 in the hidden OBC menu.

You did it completely with just NCS expert and NcS dummy?

Correct.
I opened NCS Expert and read my LCM module and confirmed which was exact module in my X5. .TRC file saved in WORK folder.
Opened NCS Dummy and BEFORE opening a .trc file, I loaded the LCM module in NCS Dummy and scrolled down to add a new 114 Deg C parameter and saved under Module Functions.
Then loaded the .TRC file and changed my temp warning setting to 114.

Opened NCS Expert and loaded new .man file and coded proper LCM module version.

Then I Opened the KMBI module in NCS Expert and read that file. .TRC file saved.
Opened NCS Dummy and loaded proper KMBI module AND .TRC file, and went to temp settings and confirmed that for my gasoline model e53 that option 4 with the same temp values as ZBoost had mentioned were in my KMBI module.
ChAnged to Opt 4 and saved .man file.
Loaded this .man file into NCS Expert and all matched.
I even reread my newly coded.module in NCS Expert and opened that .TRC file in NCS Dummy to confirm all changes took effect.

As posted before getting the numbers to change might not mean that the warning changes as well. I tested mine by fooling the DME with a decade box across the temp sender wires and tracked the temp with impa but the warning lite did not come on when the temp read over the setting. That was a while back but I think I remember not being able to get any reaction from the guage or the DME from the gauge side of the temp sender maybe I didn't try putting the decade box on the guage side and it is only used for the warning light?? Interesting for sure and would tie up some loose ends on how the system works! :) I might dig into the E-box for another project so maybe I will revisit some of this. Just want to add that I have the low guage cluster so all bets are off on how things work with the high cluster.

I think it will work when last value for the gauge (maximum) equals the setting for the alarm. Haven't tested it though but I replicate the logic of the default settings (125c).
