Remember always to create a backups before starting an endeavour!

Prerequisites: ENET cable, E-Sys 3.26.0, PsdZData files (54.0 is used in
this guide). It°Øs important that the PsdZData files are the FULL version as
the Lite version does not include all necessities for flashing. And last
prerequisite: a BMW F10 or F11. I°Øm doing this on my F11 520d. This guide
should work for all Fxx chassis. E-Sys 3.26.0 is used for screen dumps. Other
versions may differ slightly.
n this article, I°Øll be upgrading these ECU°Øs:

CMB_MEDIA
HU_CIC
KOMBI
ZGW
The steps for upgrading other ECU°Øs should be the same as doing these
four. Just remember to identify the dependencies and select appropriately in
step 15 in the below procedure.

When flashing involves ZGW it is widely said that the ZGW module should be
updated BEFORE other modules. The TAL (BMW Control Units/ECUs Abbreviation
Short Explanations) generated by E-Sys should take care of this. But if you
want, you could flash the ZGW all by itself and then restart and do the rest.
The steps remain the same. Flashing all modules at once is also as easy as
flashing individual modules. Just select all the modules in step 15 (still
blFlash, swDeploy, cdDeploy, and ibaDeploy columns)
HU_CIC Depends (PreRequisites) on: 38 + 14 (BOTH ZGW)

KOMBI Depends on: 38 + 10 + 14 + 53 + 57 (ZGW + HU_CIC + ZGW + CMB_MEDIA +
HU_CIC)
CMB_MEDIA Depends on: 57 (HU_CIC)
ZGW does not have dependencies.

How to identify dependencies:
Open TAL IN TAL Editor, and it will show you under ECU (TalLine_ID) if it
has any PreRequisite ECU (TalLine_ID°Øs).
As you can see here, TalLine_ID=13 (Kombi) has a PreRequisite of
TalLine_ID=11 (HU_CHAMP):

Basic steps:

Go to Comfort Mode => TAL-Calculating
®C Read and Save FA
®C Activate FA
®C Read and Save SVT Actual as SVT_ist
®C 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
®C 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.

Procedures coding for BMW HU_CIC/KOMBI/CMB_MEDIA/ZGW
Connect external charger (at least 50AMPs, preferably 70AMPs) to the car
battery. Connect laptop
to power supply. This step is essential!
Turn lamp switch to parking light ®C this will keep the ignition on beyond
20 minutes. (src:

#post8625168). Please refer to Appendix B for further info regarding the
light switch and the 20
minutes.
Connect via °∞Connection via Gateway URL°± (src:

Troubleshooting:
If coding ACSM, the airbag needs be locked. This can be done by using the
following procedur

E-Sys Transmitter:
1) Click °∞External Applications°± in the left menu.
2) Click °∞External Application°±
3) Double-click °∞Transmitter°±
4) Double-click °∞ACSM verriegelung_schreiben°±

Appendix B
On new cars (7/2014 F30) the ignition will not stay on even if you turn
light switch. After 15 minutes or so
ignition will turn off. This is not a problem though, just remember to
cycle ignition before svt soll
calculation and before starting TAL processing (actual flash). Ignition
will stay on as long as the TAL is running.
 
Appendix C

ibadeploy is needed only if you are flashing a headunit that has IBA
(electronic user manual). It doesn°Øt do any damage if it is selected without
a reason though.
