CAUSE
Unfavorable logic in the LED control unit hub.

CORRECTION
Follow the test plan to encode the LED control unit hub.

PROCEDURE
Determine the vehicle’s current I-level by either using AIR or the Key Reader/AWP (Aftersales Workplace)
applications.
If the I-level is …26-03-530 or higher, then continue with standard diagnosis.
If the I-level is lower than …26-03-530:
Program the vehicle to I-level …26-03-530 or higher using ISTA 4.58.2x (released on March 3, 2026) or
higher.
Connect the battery charger to the vehicle
Connect the programming system to the vehicle (ISTA 4)
Determine measures plan
Accept and fully work through the measures plan with the control units to be programmed/encoded
and enabled
Follow the rework list
Depending on the rework list, carry out a vehicle test and delete the fault memory if needed
After the programming has been completed check operation of all the individual ambient lighting elements
that they are working and displaying properly.

Note: ISTA will automatically reprogram and code all programmable control modules that do not have the
latest software.
Always connect a BMW-approved battery charger/power supply (SI B04 23 10).
For information on programming and coding with ISTA, refer to Dealer Universal Portal / TIS / Technical
Documentation / Diagnostics and Programming / Programming Documentation.

PARTS INFORMATION
No parts are required.

CLAIM INFORMATION
Vehicle Programming and Encoding
During this workshop visit, the affected vehicle may also show one or more programming and encoding Technical Campaign
repairs open, the programming and encoding procedure may only be invoiced one time.
Select one of these open Technical Campaigns instead to perform and submit for updating the vehicle to the
required I-level, or higher when applicable (Includes labor operation codes 00 00 006/556, 61 21 528 and 61 00 730).
Please be sure to also perform any additional before and/or after work (including attaching labels) as required by
the open campaigns on the vehicle. Close any remaining open programming and encoding Campaign repairs as

Vehicle Programming and Encoding – Additional Work (RO and Claim Comments Required)
This procedure automatically reprograms and encodes any vehicle control modules that do not have the latest software Ilevel.

If one or more control modules fail during the reprogramming procedure, claim the required consequential
repair work procedures to address this issue (including performing the IRAP Control Unit Recovery first as
required, refer to the SIB in AIR) under the Repair Code in this bulletin together with the corresponding labor
operation codes and their flat rate unit (FRU) allowance(s), including the diagnosis* that applies.
Please explain the additional work procedures that were performed (The why and the what) on the repair order and in the
claim comments.

For covered repairs that address control module failures that occurred prior to performing this
reprogramming procedure, claim this work with the appliable Repair Code listed in AIR together with the
corresponding labor operation codes and their flat rate unit (FRU) allowance(s), including the diagnosis* that
applies.
(*) Based on which one applies to your center, please refer to SI B01 01 20 or B01 07 20 for the applicable procedure for
documenting, claiming, and explaining, on the RO and in the claim comments, your diagnosis work time (WT), job/repair
work time (WT), and the vehicle repairs your center performed, unless otherwise required by State law.
