Abrasion Marks on Rear Drive Shaft: Replacing Air Bellows, Checking Rear Drive Shaft and
Replacing if Necessary (124/23)
Model Line:
Cayenne (9YA / 9YB)
Model Year:
2024
Equipment:
Adaptive air suspension with levelling system and height adjustment including Porsche Active Suspension
Management (PASM) (M-No. 1BK / 2MA / 2MB)
Concerns:
Air bellows and rear drive shaft
Information:
During the endurance test, intermittent paint abrasion (abrasion marks) was detected on the
rear drive shafts.
Cause:
Due to an incorrect wall thickness of the air bellows, contact between the drive shaft and air bellows can
occur in certain driving conditions, e.g. at full load in combination with high spring compression rates.
Action:
In the event of a complaint, the rear air bellows must be replaced with air bellows with a new component
status, the rear drive shaft must be checked and replaced depending on the test result.
