SUBJECT

Outside Mirror Moves when Unlocking the Vehicle

 

MODEL

E90, E91 (3 Series Sedan andSports Wagon) produced up to 9/2008 and equipped with power front seats, optioncode SA459

 

 

SITUATION

When unlocking the vehicle via the remote key fob or the centrallocking button, the driver's side outside mirror moves unexpectedly.This condition occurs intermittently. When the mirror moves, it seemingly goesto a random position. Pressing the seat memory button typically will return themirror to the stored position.

 

CAUSE

When the unlock signal is sent to the car, a mirror position self-check isperformed. One of the factors in determining the mirror's present position isan expected resistance value in the circuit. Due to a higher than expectedresistance, the Footwell Module (FRM) calculates the mirror positionincorrectly. The mirror is then moved to what is believed to be the correctposition. The unexpected resistance value is caused by one of the following:

 

* Corrosion on the LIN-bus connection at the mirror, switch block, or FRM

 

* Poor connection at the mirror, switch block, or FRM

 

* Damaged mirror electronics

 

CORRECTION

Repair or clean the appropriate connections. In isolated cases, the mirrorelectronics need to be replaced.

 

PROCEDURE

 

1. Reproduce the customer complaint by locking and unlocking with theremote key fob or central locking switch.

 

2. Remove the driver's side door panel per Repair Instruction RA 5141 000.

 

3. Remove the window frame trim panel, which covers the mirror connection, perRepair Instruction RA 51 32 160.

4. Unplug the connector from the mirror.

 

5. Inspect the connector for any damaged or poorly fitting terminals.

 

6. If any damage is found, repair or replace the connector and/or terminals.

 

7. Remove the terminals one by one, and clean thoroughly with electricalcontact cleaner.

 

8. Apply a small amount of dielectric grease to the contact side of theconnector.

 

9. Reinstall the connector.

 

10. Attempt to reproduce the customer complaint again to determine whether theproblem has been resolved.

 

11. If the problem has not been eliminated, continue with the followingprocedure.

 

12. Inspect the connector at the door switch block to check for damaged orpoorly fitting terminals which lead to the mirror, as well as those leading tothe FRM. These are pins 1, 2, 3, 10, 11, and 12.

 

13. If any damage is found, repair or replace the connector and/or terminals.

 

14. Remove the terminals one by one, and clean thoroughly with electricalcontact cleaner.

 

15. Apply a small amount of dielectric grease to the contact side of theconnector.

 

16. Reinstall the connector.

 

17. Attempt to reproduce the customer complaint again to determine whether theproblem has been addressed.

 

18. If the problem persists, remove the mirror cap per Repair Instruction RA 5116 040.

 

19. Inspect the wiring of the mirror electronics for damage or poorconnections.

 

GRUSB5108-30

 

 

 

20. Unplug the mirror electronics (1) and clean the connection (2) on the backside with electrical contact cleaner.

 

21. Attempt to reproduce the customer complaint again to determine whether theproblem has been addressed.

 

22. If the problem persists, replace the mirror electronics for the driver's sidemirror for vehicles not equipped with auto dimming/power fold mirrors(SA430),or the complete mirror for those equipped with auto dimming/power fold mirrors.
