CORRECTION

Do not replace any parts!

E60, E61/N54 vehicles

Program the vehicle with ISTA/P P2.45.0 (available from December 2011) to integration level E060-11-12-500 or higher.

E89/N54/N54T vehicles

Program the vehicle with ISTA/P P2.43.x or a more recent version to integration level E89x-11-09-501 or higher.

E92, E93/N54T vehicles

Program the vehicle with ISTA/P P2.43.x or a more recent version to integration level E89x-11-09-501 or higher.

F01, F02/N54/US vehicles

Program the vehicle with ISTA/P P2.41.0 or a more recent version to integration level F001-11-03-502 or higher.

If the problem occurs on a vehicle that already has the integration level given above, perform diagnostics with ISTA/D.

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

For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle
