AFFECTED VEHICLES
This Service Action involves E70 and E71 vehicles with N55 engines produced from 7/12/2010 to 11/20/2010.
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 590. If code number 590 has been punched out, the campaign has already been performed. If code number 590 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 2.40.3 or later.
Vehicle integration (new): E070-10-12-503 or later.
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 590. After the vehicle has been checked and/or corrected, obtain a label (SD 92-395) and:
A. Emboss your BMW center warranty number in the middle of the label (1);
B. Punch out code number 590 (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.
