Allow the vehicle to enter a full sleep cycle. If necessary, this measure can also be carried out by the customer before
arriving at the dealership.
Restart the head unit via a long press of more than 70 seconds on the volume control button (head unit reset). In the
event of a fault and ONLY when stationary, this can also be carried out by the customer before arriving at the
dealership.
Perform a 12 V battery reset (disconnect the vehicle battery)
If the previous steps resolved the issue OR the issue is sporadic and not currently occurring:
If any relevant faults are stored, carry out a diagnosis with ISTA and work through the corresponding test module if
available
Perform any available Remote Software Upgrade currently downloaded to the vehicle. Reference SI B09 01 25 for
more information.
If there is not a current RSU available in the vehicle, program the vehicle with the current ISTA version
Program the vehicle using the most current version of ISTA.
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 fully completed, check functionality of the system.
As long as there is a software level available via Remote Software Upgrade or ISTA that is higher than the Ilevel in the vehicle, programming should be performed. No I-level is specified in this bulletin because each
newer version of software will incorporate additional software changes. Any vehicle experiencing the listed
head unit failures should be updated to the latest software version possible, even if previously updated.
Note: This bulletin allows for the programming of any applicable vehicle, as long as the software I-level is
being updated. Programming a vehicle to the same installed I-level does not provide a fix and will not be
covered.
Note: ISTA will automatically reprogram and code all programmable control modules that do not have the
latest software.
Note: In most cases, parts replacement does not provide a remedy and is therefore not permitted before programming has
been performed
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.
CLAIM INFORMATION
