SUBJECT: All Model 211 Vehicles, As of VIN A554000 or March 19, 2004 Production Date
Seat Common Structure (SCS) Memory Function or Fore/Aft Adjustment Faults

If you receive customer reports in the above model vehicles that the Seat Common Structure (SCS) front seats have either a memory function fault or moves fore/aft in short steps, the plug in the seat fore/aft adjustment motor (Figure 1) may have been connected incorrectly. This leads to a fault in the Hall sensor and may cause the normalization settings of the seat fore/aft adjustment to be lost. To correct, raise the seat completely upwards, remove plug and insert correctly (Figure 2).










Possible Complaints on the Driver Side:

- Memory function of electric seat fore/aft adjustment not functioning

- Seat fore/aft adjustment with easy entry/exit feature not functioning

- Head restraint presetting (head restraint is set automatically in relation to the position of the fore/aft adjustment) not functioning

- Seat fore/aft adjustment can only be adjusted for 2 seconds with the seat adjustment switch (seat can only be adjusted in longitudinal direction with a start and stop motion)

Possible Complaints on the Passenger Side:

- Memory function of electric seat fore/aft adjustment not functioning

- Function "Collision avoidance when folding down the rear seat backrest" not functioning (seat fails to move forward when the rear seat backrest is folded down)

- Head restraint presetting (head restraint is set automatically in relation to the position of the fore/aft adjustment) not functioning

- Seat fore/aft adjustment can only be adjusted for 2 seconds with the seat adjustment switch (seat can only be adjusted in longitudinal direction with a start and stop motion)
