NO SIGNAL iDrive

I was Coding my F80 when after did in all modules, I let the iDrive for last. After I did the changes and press Code, an error apeared on Esys and iDrive seems to fail the reboot. After that, all that appears on iDrive is NO SIGNAL message, and now when I try to Read (ECU), Hu_NBT no longer appears.

Does anyone know what may have happened and how do I solve this problem?

Just a guess. It's likely the screen resolution was coded to a setting it doesn't support. This obviously would've happened by accident when you were coding something else. Once the correct screen hardware and resolution is coded again, the screen should work just fine. An experienced coder should be able to get this resolved for you.

Try to read CAFD, if non communicative - check power/fuses.

The only parameter that I changed in HU_NBT was to add 5 blinkers on the Exterior Light Settings (at least that I remember), the problem is that now HU_NBT doesn't appear anymore when I read (ECU)

All the fuses are ok, I've already check. What specifically do you mean about read CAFD? Detect CAFD for SWE?

Hi,
If HU_NBT2 does not come up when you READ_ECU it is probably bricked.
CAFD or anything else won't help you.

Try to ping with cmd 169.254.199.99 and let us know.

Thanks

I received the same message yesterday and I have not done any coding on my 2019. After shutting it down for a few hours, the iDrive is working again.
