AFFECTED VEHICLES
This Service Action involves F02 vehicles with the N74 engine which were produced from 4/14/2008 to 2/18/2010.
In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar
label for code number 563. If code number 563 has been punched out, the campaign has already been performed. If code number 563 has not been
punched out, it will be necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the
response of the system, either proceed with the corrective action or take no further action.
PROCEDURE
Program the vehicle using ISTA/P 2.37.0 or a more recent version.
F02 - Integration level (new): F001-10-03-501 or higher.
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to Centernet / Aftersales Portal / Service / Workshop Technology / Vehicle
Programming.
LABEL INSTRUCTIONS
This Service Action has been assigned code number 563. After the vehicle has been checked and/or corrected, obtain a label (SD 92-380) and:
A. Emboss your BMW center warranty number in the middle of the label (1);
B. Punch out code number 563 (2), printed on the label; and
C. Affix the label to the B-Pillar as shown.
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.
