Due to a software flaw, the flap control system may become deactivated in the vehicles listed above.
The software flaw switches off the function of the actuator motors for the temperature and ventilation flaps. This can impair the driver's vision (windows fogging up) and comfort. The codes B0233, B0408 and, in some cases, B0418 are stored in the error memory.
Vehicles with the following chassis numbers are affected:
W0LGM6EL2B1101156 to XXXXX 8EY3B1129491
The problem can be remedied by performing a software update.
