The INITIAL NAV enabling code no longer needs to be pre-ordered through the Parts department! When the vehicle is connected to the diagnostic system ISTA to perform PDI/QC1 the step to activate the navigation system (part of Delete Transport Mode) will automatically request the INITIAL NAV enabling code (VIN-specific) without pre-ordering the enabling code. This enabling code will be automatically delivered through ISTA and it then activates the navigation system.

The 12 V batterys dual storage system (DSS) may contain a software error which intermittently causes a continuous resetting of the microcontroller and communication failure. The error is displayed by a red Check Control message.

If one or more of the following components needs to be replaced, the secure connection between them must be re-established: MGU TCB Telematic Communication Box (ATM-02) RSE Rear Seat Entertainment and/or KOMBISP18 instrument cluster Prior to re-establishing this connection, an electronic certificate must be created in the BMW backend for importing into the Vehicle. After the replacement of one of the mentioned Modules, the Control Module needs a valid certificate for it to communicate with the other Modules.

In these circumstances: A crash shutdown of the DSS does not occur The power distribution box is supplied with power until the DSS is fully discharged

from the outside using the remote control: The doors lock The alarm system is not activated The side mirrors (when the function is activated) do not fold in CAUSE Due to a software error on the Body Domain Controller (BDC) it identified the remote control as being inside even though the remote control is actually located outside the vehicle. This caused the doors to be locked without securing the vehicle.

Remote control functionality is restored by pressing any of the key buttons or by removing and reinstalling the remote control key battery. The Display Key Digital Key and the Digital Key Card are not affected. Electrostatic discharge puts the remote control key into a deep sleep. Various situations can lead to an electrostatic charge which is often not recognized by the customer. For example walking over carpet wearing shoes that have a hard rubber sole positive and negative charges are exchanged. The sole accumulates a negative charge and an electrostatic charge develops before touching the remote control key.

The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.
