AFFECTED VEHICLES
This Service Action involves E71 vehicles with N63 engines which were produced up to 4/04/2009.
In order to determine whether a specific vehicle is affected by this Service Action, 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.
The chassis number ranges listed are only for informational purposes, and are not to be considered as the only deciding factor.
1. Perform a vehicle test.
2. Program the vehicle using ISTA/P 2.33.2 or later.
3. Continue the vehicle test to complete all rework procedures as listed in the ISTA/P final report and to clear the fault memory.
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 539. After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-352) and:
A. Emboss your BMW center warranty number in the middle of the label (1);
B. Punch out code number 539 (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.

Covered under the terms of the BMW New Vehicle Limited Warranty.
