Cannot set time after 6WA retrofit

unlawfulsquirrel · 02-24-2024, 08:16 AM

Hey guys!

After retrofitting a 6WA cluster I cannot set the date/time anymore on my iDrive display. The KOMBI ecu seems not to respond on both ISTA and Esys. I can actually go into settings and change the date/time but the car won't register the changes and display "--:--" on both the iDrive and the cluster. Also, the car stopped chiming for seat belt alerts, temperature alerts, etc. Just for info, I also had to add the MOST cable from the iDrive to the cluster. Everything else is working flawlessly.

After reading some old threads I tried the following FDL codings in the HU_NBT ecu but to no avail:

KOMBI_CIC → kombi_High (also tried kombi_Low but doesn't work)
BASIS_KOMBI_MMI_LIST → nicht_aktiv
EXTERNER_MOST → aktiv
EXTERNE_MOST_DIAG → aktiv
SETTINGS_INFO_DISPLAY → aktiv

The thread also said to change NAVI_NBT_ENABLE → kein_nbt in the DKOMBI ecu but as said before the ecu doesn't seem to respond.

I am also attaching the screenshots of what I see on ISTA/Esys in case it might be of help. (On ISTA, B7F8C3 is due to using an android head unit, always been there since the installation but never really had any issues, 104302 is due to JB4)

Any help would be gladly appreciated, thanks.

Your 6wa is not there. You need to code hu first with 6wa in FA then read ecu and try to inject cafd. Did you connect most cable from hu to cluster?

Siki78 Hey! I did connect the MOST cable. I tried to code the HU but now the KOMBI ecu won't show up at all unfortunately...

You need to remove bkombi from fa to be able to see 6WA. I write you PM

Siki78 Hey man, thank you so so much for your help again. Unfortunately even after replacing fuses, Esys still won't show KOMBI ecu. However, ISTA is now saying "there are differences between the vehicle order and the stored MOST configuration", I think that if somehow I manage to change the MOST configuration Esys may finally start seeing the KOMBI.

Hey guys, turned out to be a broken MOST cable, replacing it did the job.
