A/T - Intermittently Goes Into Park During MSA Engine Start
SI B24 08 12Automatic Transmission
December 2012
Technical Service
SUBJECT
Transmission Intermittently Goes into Park During an MSA Engine Start
MODEL
F10 with the N20 engine
Produced to June 2012
SITUATION
The transmission can intermittently go into the Park position (P) when an MSA engine start is occurring.
A drive gear can be selected in order to drive away, and no relevant faults are stored.
This problem is very sporadic, can be difficult to reproduce, and usually only began after the vehicle was programmed with ISTA/P versions 2.47.1 through 2.48.1.
Vehicle integration levels affected:
F010-12-07-531
F010-12-07-533
F010-12-11-501
F010-12-11-502
All F10 N20 vehicles produced July 2012 and later are not affected, regardless of the integration level.
CAUSE
Unfavorable EGS software
CORRECTION
If the vehicle falls within the production range and is currently at one of the affected integration levels, it will need to be programmed with the latest version of ISTA/P to a new target of F010-12-11-503 or higher.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle Programming.
Note:
When the ISTA system message displays:
Battery voltage only "XX.XX" V. Please connect charger.
Please note the displayed battery voltage reading in the repair order
comments section. This documentation is not necessary when part of an approved Technical Service repair procedure; the battery charger is required to be attached before performing the Vehicle Test.
