Technical Service
This Service Information bulletin supersedes SI B11 11 12 dated November 2012.
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE
CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
BMW centers must ensure recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a
safetyrelated defect or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession
at the time of notification. In BMW NA's case, this notification would typically be made by the issuance of a recall notification in
the form of a Service Information bulletin (SIB) or transmission of a Dealer Communication System (DCS) recall message.
Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a recall campaign is announced by BMW NA,
centers must ensure that all recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery
to the consumer. This means that centers may not legally deliver new motor vehicles or new items of replacement equipment to
consumers with an open recall.
The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until
the open recall has been completed BEFORE delivery. This also pertains to vehicles in the Certified PreOwned program, and to
items of replacement equipment.
Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions
provided by BMW NA on the return or disposition of the parts.

steering effort.
AFFECTED VEHICLES
This Recall Campaign involves E70 X5 vehicles with the M57Y engine produced from September 2008 to November 2012.
In order to determine whether a specific vehicle has had this Recall Campaign completed or is affected by this Recall Campaign,
first check the Bpillar label for code number 632. If code number 632 has been punched out, the campaign has already been

Communication System) or the Key Reader. Based on the response of the system, either proceed with the corrective action or
take no further action.
