This bulletin applies to 2021 BMW 2 Series Gran Coupe, X3 Sports Activity, X4 Sports Activity, X5 Sports Activity, X6 Sports Activity, X7 Sports Activity, 8 Series convertible, Coupe and Gran Coupe, 3Series sedan, 4 Series coupe, convertible and Gran coupe, 2 Series coupe and Z4 Roadster vehicles.
The gear selector switch (GWS) consists of the control electronics circuit and the selector lever. The sensors for recording the gearshift lever position and for inhibiting inadvertent gearshifts are integrated in the control electronics.
When fault code 802683 (selector lever knob exchange without disconnection of battery) is stored, this indicates that the GWS was exchanged without isolating the vehicle battery. Removal of electronic components without first disconnecting the battery may result in a short circuit, causing damage to the component.
Once fault code 802683 is stored, it cannot be deleted and only becomes inactive after a GWS replacement. This is not a defect in the control unit.
Whenever the fault code 802683 is stored with additional faults then the gear selector switch control module is also faulty and must be replaced. Or, whenever the fault code 802683 is stored without additional fault codes in the gear selector switch control unit, then the fault memory entry can be ignored. If the customer does not wish to have the GWS control unit replaced, it will continue to function.
