Air in hydraulic system
Cars affected
Saab 9-3 Convertible M99 within VIN interval
X7023727 - X7050589.
Background
The hydraulic system on a limited number of cars may contain air bubbles. These bubbles may cause problems when operating the soft top. The fifth bow may not move, the soft-top cover may stop midmovement and noise may emanate from the system. The following measures can be taken after customer complaint.
Procedure
1. Operate the soft top so that the soft top cover and fifth bow are fully raised.
Note:
Use the emergency operation function if the soft top can not be operated hydraulically.
2. Use a rag to cover the upper hose connection of the fifth bow cylinder on the left-hand side of the car.
3. Undo the upper connection on the fifth bow cylinder on the left-hand side of the car.
Does oil run from the hose?
^ YES
The hydraulic system is functioning properly and there are no air bubbles present. Reconnect the hose and tighten it.
^ NO
Leave the connection open (so that the end of the hose is visible) for about 5 minutes (the system will now slowly take in air). Then, go to step 4.
4. Connect the hose and make sure it is tightened securely.
5. Operate the soft top for one complete cycle to its lowered (open) position and then up (closed) again.
6. Check the hose to make sure there are no leaks.
7. Wait for one minute so that oil and air has time to separate in the reservoir.
8. Operate the soft top for another complete cycle lowered/raised (open/closed).
9. Allow the car to stand for 10 hours.
Important:
The car may be moved (driven) but the soft top must not be operated.
10. Operate the soft top for 2 cycles and listen for noise while looking for jerky soft-top movement caused by air in the system.
Is the soft-top functioning correctly?
^ YES
The car is OK.
^ NO
Allow the car to stand for 20 minutes.
Important:
The car may be moved (driven) but the soft top must not be operated.
Then, go to step 11.
11. Operate the soft top for 2 complete cycles lowered/raised (open/closed)
12. Allow the car to stand for 10 hours.
Important:
The car may be moved (driven) but the soft top must not be operated.
13. Repeat steps 10 to 11 until the soft top operates quietly and smoothly.
