PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION
ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE
NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if there has been a recall campaign, dealers must assure that all new vehicles and new items of replacement equipment are free of safety defects and comply with all applicable Federal Motor Vehicle Safety Standards at the time of delivery to the consumer. This means that dealers may not deliver new motor vehicles or new items of replacement equipment to consumers unless the safety defect or noncompliance has been remedied before delivery.
SUBJECT
Safety Recall Campaign 05V-504: Parking Lock Guide Plate
MODEL
E65, E66 with N62TU, N73 from 08/05 up to 10/05
E60 with N62, N62TU from 08/05 up to 10/05
E63, E64 with N62, N62TU from 08/05 up to 10/05
E53, X5 4.8is with N62S from 08/05 up to 10/05
SITUATION
Some of the ZF 6HP26 automatic trans missions installed in the affected vehicles have been assembled using non-hardened parking lock pawl guide plates. A non-hardened guide plate can cause a misalignment of the lock pawl to the park wheel, resulting in a partial engagement of the transmission parking lock.
If the transmission parking lock was not fully engaged and the vehicle was parked on an incline of a sufficient grade, with the parking brake not applied, this could result in a vehicle rollway condition.
In order to remedy this situation, BMW is conducting a Safety Recall Campaign to replace the automatic transmission guide plate on all affected vehicles.
A copy of customer notification letter is included.
To minimize the customer inconvenience caused by this Recall Campaign, pick-up (and deliver after repair) the affected vehicle from customer's home and provide appropriate alternative transportation.
Customers will be impressed when you return their cars cleaned inside and out and with a full tank of gas. Reimbursement information for the vehicle fueling and valet costs may be found in the Warranty portion of this bulletin.

The Chassis Number Ranges listed are only for informational purposes and are not to be considered as the only deciding factor.
CORRECTION
On the affected vehicles replace the automatic transmission pawl guide plate (PN 24 53 1 219 287).
PROCEDURE
1. Prior to parking pawl guide replacement, transmission has to be cooled down. Transmission oil temperature must to be below 100 deg F.
2. Turn off the engine, engage parking/hand brake and select neutral (N).
IMPORTANT NOTE:
On the E65/66 vehicles, the Emergency Parking Lock Release has to be engaged. The emergency release for the parking lock is located in the vehicle interior at the A-pillar in the foot well on the driver's side (above the hood release handle). This emergency release can be only accessed by using vehicle key to open the locked cover. With cover unlocked, pull the red ribbon until the release handle locks-up. After repair is completed, the emergency release must be reset (handle pushed back) to re-engage the parking lock.
3. Raise vehicle on the suitable lift and remove the underbody shield cover.
4. Drain and save lifetime-fill transmission fluid.
5. Remove transmission oil pan (for removal instructions refer to TIS RA 24 11 010).

10. Make sure that there is a clearance between the parking pawl and the gear wheel and the pawl is not sticking/binding in the guide plate (check point indicated by an arrow.
11. Install a new transmission oil pan seal/gasket. On E60/63/64/65/66 vehicles, also replace the transmission pan sealing O-ring (PN 24 11 7 520 714).
Important:
Prior to pan seal installation, make sure that the oil pan and the seal groove are cleaned and free of oil residue.
12. Reinstall transmission's oil pan. Tighten the retaining bolts in a symmetrical order using torque of 10 Nm.
13. Install a new drain plug using torque of 8 Nm.
