REPLACEMENT TELEMATICS MODULE CANNOT BE PROGRAMMED
BY ISTA

MODEL
E-Series
G26
i20

Model Description
4 Series Gran Coupe
iX Sports Activity Vehicle

Affected Option Code
With SA 6PA – “Personal eSIM”

SITUATION
After the telematics module (TCB4) has been replaced, the replacement part control unit is not accepted by
ISTA.

CAUSE
The replacement telematics module (TCB4) is built by a different supplier.

CORRECTION
Perform an ISTA conversion to add the K-word “ERWA” to the Vehicle Order. This will alter the TCB4 coding.

PROCEDURE
Determine what is the vehicle’s current I-level by either using AIR or the Key Reader/Aftersales Workplace
(AWP) application.
The TCB4 replacement parts are changing supplier versions from WAVE-11 High to WAVE-01 High. This
change in hardware will not be accepted in ISTA when performing programming for replacement.
When replacing the TCB4 due to a failure, make sure to check the information sticker in the replacement
module for the version.

For ISTA to accept the hardware change from WAVE-11 to WAVE-01, the programming conversion
“Replacement of WAVE11 to WAVE01” will need to be performed AND the vehicle will need to be
programmed to I-level …25-07-500 or higher.
If the original module is a WAVE-11 high and the replacement module is a WAVE-01 High, perform the following
steps:
1. Verify ISTA 4.54.3x (released July 22, 2025) or higher is installed at the dealership.
2. Install the replacement TCB4 (WAVE-01 High) in the vehicle.
3. In ISTA, select the conversion “Replacement of WAVE11 to WAVE01” using the following path:
Vehicle Management
Vehicle Modification
Conversion
“Replacement of WAVE11 to WAVE01”
4. Perform the conversion, and program the vehicle to I-level …25-07-500 or higher.

ISTA will automatically reprogram and code all programmable control modules that do not have the latest
software.
