MGU is on at least S18A-25-03-510 or newer
BDC is between S18A-24-07-520 and S18A-24-07-564
KOMBI is consistent with S18A-24-07-530

(haven't checked others)

I don't know if that could be the problem given only coding is different on MGU compared to S18A-24-07-530, but that indicates that owner is not telling the truth.

P.S. Unless it was you who coded it to too new level.

... but that indicates that owner is not telling the truth.

...as usual.
From my side, I cant understand the use of FI code to get component protection solved for the MGU without knowing the reason for component protection.

Couldn't agree more!

Thanks for checking.
No, I did not code or played with coding data of the MGU.
I noticed in i5тд report, the DTC 026308 which is MGU : uncoded, with current mileage
Could FI recode the MGU with different coding data?

No one know what happened to the car, I just tought I should start with this + OEM f5с.
My knownledge is not enough to diagnose CP triggering outside of BDC/HU replacement, and that is why I am asking you
And I thank you for spending time to help me

If the customer claims that the cause was the 5ёяvїcё performed.
I’m also very interested in why the customer is coming to you instead of the dealer where they had the 5ёяvїcё done.

It’s the holidays right now and I may not remember well, but for the MGU the latest update was 23-11-540.
Then there were changes only to the coding file.

5ёяvїcё was done in Portugal, and now car is in France.
I have asked again client, and now he is unsure that this happened right after the 5ёяvїcё...
Anyway, I wonder how a 5ёяvїcё at BMW dealership could cause this.

In any unclear situation with an HU MGU, I recommend starting with an ABL Factory Reset.

Anyway, I wonder how a 5ёяvїcё at BMW dealership could cause this.

As I wrote already - I suggest that last 5ёяvїcё has nothing to do with the current problem.
Btw. - I am not sure if the car got the last 5ёяvїcё at a BMW dealership, I didnt know the dealer, but he is also offering some other brands.

Also would it be possible that he didnt connect the car to a dїдgиo5тїc terminal - because the last 5ёяvїcё got written by keyreader.

Thanks for all the inputs guys.
I will assume that this is unrelated to 5ёяvїcё

After spending some time to search accross forums, I have found several very similar cases for the instrument cluster
Some of them fїжed the issue by software update (SIB 62 01 19)
Some others had to replace dkombi

IF firmware levels are same, then MGU itself would be as good a suspect to me along with KOMBI, because KOMBI is not connected to BDC directly but via MGU instead...

I see on SSP that cluster has PT-CAN to BDC and Ethernet to MGU, since this car has no DCS.
Does ethernet play a crucial role in waking up cluster ?

[Bugfїж]

The funny thing is that the instrument cluster doesn’t рдятicipate in the vehicle’s component protection at all.

Even if you disconnect the instrument cluster from the head unit, the head unit will still continue to work.
