Service Action Label
Instructions:
This Service Action has been assigned code number 236. After the vehicle has been
checked, and corrected if necessary, obtain a label (SD 92-095) and:
a) emboss your BMW dealer warranty number in the middle of the label (1);
b) punch out code number 236 printed on the label and,

If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the
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.
