Service
Action Label
Instructions: This Service Action has been assigned code number 20. After the prescribed work has been performed, obtain a label (P/N 01 99 9 750 968) and

a) emboss your BMW dealer warranty number in the middle of the label.

b) punch out code number 20 printed on the label.

c) bend label to crease an edge and remove the backing paper. Then affix it to the "B" pillar (on driver's front door) as shown.





If the car affected already has a label from a previous Service Action/Recall Campaign, affix this new label next to the old one. Do not affix one label on top of another one because a number from an underlying label could appear in the punched out hole of the new label.

Vehicles which already have a label with code number 20 punched out do not need to have a second label installed.
