CAUSE
DSC software application.

CORRECTION
Program and encode the vehicle using ISTA 4.24.1x to I-Level S18A-20-07-520 or a more recent version.

the latest software.
Always connect a BMW-approved battery charger/power supply (SI B04 23 10) when performing
programming.
Do not replace any parts for this issue.
If the I-level is S18-20-07-520 or more recent (higher), perform further diagnosis with ISTA.
