Door Lock System Diagnosis and Repair
Vehicle Type:
Cayenne/Cayenne S/Cayenne Turbo
Model Year:
As of '03 (3)
Concern:
Complaints and malfunctions on door lock/door locking system.
Information:
This Technical Information provides an overview of possible complaints in the door lock and door locking system and the required remedial measures.
Complaint:
Outer door handle gets stuck in actuated position or does not fully return to its original position.
With too little clearance between the bearing pins on the door handle and the respective mounting in the supporting bow of the door handle in the vehicle door, as well as in the area of the sliding surface between the grip hook on the door handle and the lock cylinder (driver's door) or the lock cylinder housing (remaining doors), the door handle can get stuck in the actuated position or not fully return to its original position.
In the case of a complaint, the bearing surfaces on outer door handle, as well as the sliding surfaces of the guide for the lock actuation on the door handle, and on the lock cylinder (driver's door) or on the lock cylinder housings (of the remaining doors) need to be lubricated.
Parts Information
Work Procedure:
Grease sliding surfaces on the lock cylinder or on the lock cylinder housings and on outer door handle,
Grease bearing surfaces of outer door handle.
1. Remove outer door handle, see Cayenne Workshop Manual, Group 5, 57 11 19 Removing and reinstalling front door handle and 58 11 IN - Removing and reinstalling rear door handle.
Note:
Do not completely remove the door handle on vehicles with Porsche Entry & Drive, instead only disengage door handle on the side of the guide for lock actuation and swivel out 90°. Grease door handle in this position.
2. Grease sliding surfaces and bearing surfaces.
2.1 Completely and lightly grease sliding surface on lock cylinder (driver's door) or on the lock cylinder housings (remaining doors) over the entire length with a brush using door lock grease, part number, 000.043.206.17 (Figure 1).
2.2 Using a brush, lightly grease the bearing hooks on the door handle (in front in direction of travel) on the upper and lower sides (Figure 2, arrows A) and in the area of the holding slot (Figure 2, arrow B).

Identifying feature - The slot in the cover of the lock cylinder where the key bit of the vehicle key is inserted (Figure 4, arrow) is not vertical.
Remedying the fault a):
1. Swivel out the key bit of the vehicle key and insert completely into the lock cylinder.
2. Turn the vehicle key in one direction until the free wheel lock engages audibly and is felt to engage on the key. The function of the lock cylinder has been reestablished.
Cause of fault b):
