How can I verify my F11's software version?

What is your I-Step Current from VCM:

My car will be in the workshop till Monday.
Hope can see that on Tuesday. I'll revert again then. Tks

It's possible to revert to older versions? Is it possible to downgrade from 55.0?????

Most likely it is possible, but is is hard to know with certainty.

Please tell me the version and year of your bimmer and why you want to downgrade.
Tks

He wants to downgrade 55.0 to 54.1 as 55.0 isn't codeable due to BMW AG Trimming the PSdZData CAFD files in newer releases.

Tks Shawn!
And that's good to know. In that case, should I decide to update mine, I have to be careful not going to that one...
Regarding my I-Step Current information I was supposed to tell you, I’ll pick up my bimmer today from the workshop and hopefully later today I’ll post it.

Hi Shawn,
Got my F11 from workshop and the news are not good.
But first let me tell you what I got from VCM - see attached.

The bad news are that they told me they updated the software to v55 because of the new window lift they replaced - what a bad luck! So long waiting to code it and now this...

Nevertheless they told me it is possible to downgrade, but a special authorization needs to be requested - don't know very well what this means but I'm hoping to be successful.

What can you tell me?
Does my I-Step reading confirms it?

Yes, F010-15-03-501 = ISTA/P 2.55.0.

Does that mean I can´t code anything?
What will be the result if I try?

Is there any way of being able to code it in the near future? A new E-Sys release perhaps?

You can try, but for any ECU that has Trimmed CAFD you will not be able to find any FDL Codes.

No new E-Sys will solve this. The issue is all descriptive text has been removed from most of the PSdZData files.

So what I'm reading looks like downgrading seems plausible but no one knows how to actually do it am I right?

I don't know the answer to that question. For now, the only way I find it to be possible - still to be confirmed - is through the BMW workshop.

Hi Shawn,
After a while back in garage...
Belt warning shorted with your help note. Thank you.

But still cannot find:
HUD_ENTERTAINMENT_ENABLE = aktiv (ovbiously entertainmnent)
HUD_TELEFONANRUF_ENABLE = aktiv (incoming call in HUD)
HUD_TELEFONBUCH_ENABLE = aktiv (recent phone calls list in HUD)

searched everywhere
I see enabling for blinker only....

what to do now??
Thank you, Tony

You flash ECU's with E-Sys and older (i.e. 54.1) PSdZData.

Kombi must have at least 2.47 Firmware on it. Your Kombi has only 2.45 Firmware.

Could you explain the steps? Is this safe to do?

It's fairly safe so long as car is on a good commercial grade charger rated for 50 Amps minimum. But anytime you flash an ECU, you run the risk of bricking it.

Here are the basic steps:

Go to Comfort Mode => TAL-Calculating
- Read and Save FA
- Activate FA
- Read and Save SVT Actual as SVT_ist
- Create an SVT Target
Under KIS/SVT Target Calculation Strategy, select Complete Flash
Select I-Step (shipm.) to match your original I-Level as read and shown in VCM I-Step (Shipment)
I-Step (target.) will be unselectable as it is fixed based on current PSdZData I-Level
Do a KIS/SVT Target Calculation and Save as SVT_soll
- Do a TAL Calculation and Save as SVT_tal

Go to Expert Mode => TAL-Processing
Load TAL (SVT_tal)
Load SVT Target (SVT_soll)
Select "Read FA" button.
Check radio button for "read VIN out of FA"
On ECU Tab, uncheck let top box in column "All" (All checked boxes should toggle to unchecked)
On ID Base Row for Kombi, make check boxes in blFlash, swDeploy, cdDeploy, and ibaDeploy columns.
Press Check software availability
Press Start and it will proceed with processing TAL to flash Kombi with new firmware.

Shawn, thank you for explanation. Exactly as I suspect from beginning...
Now, is there any chance for me to go 2.47?
Can I do it or dealer must??

Dealer would need to program the car, or you could flash it with E-Sys.
