LABEL INSTRUCTIONS

This service action has been assigned code number 296. After the vehicle has been checked, and corrected if necessary, obtain a label (SD92-155) and:

1. emboss your BMW dealer warranty number in the middle of the label (1);
2. punch out code number 296 printed on the label and,
3. affix the label to the B pillar as shown in Fig 1 .

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.

WARRANTY INFORMATION

Reimbursement for this service action will be provided through campaign entry without regard to vehicle age or mileage.
