Copies of the customer notification letter and Q&A are shown in this bulletin.
To minimize the customer's inconvenience caused by this Service Action, pick up (and deliver after repair) the affected vehicle from the customer's home or provide appropriate alternative transportation.
Customers will be impressed when you return their cars cleaned inside and out and with a full tank of gas. Reimbursement information for the vehicle fueling and valet costs may be found in the Warranty portion of this bulletin.

In order to determine if a specific vehicle is affected by this Service Action, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communication System) or Key Reader. Based on the response of the system, either proceed with the corrective action or take no further action.
PARTS INFORMATION

a. Emboss your BMW dealer warranty number in the middle of the label (1);
b. Punch out code number 473 printed on the label (2) and,
c. Affix the label to the B pillar as shown.
