WPM9 - Replacing Rear Axle Air Spring Bellows (Workshop Campaign)

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 spring bellows on the rear axle

Cause:

The rear axle air spring bellows may not have been manufactured according to specifications
on affected vehicles.
It cannot be ruled out that the rear axle air spring bellows will lose pressure over its service life, causing
the vehicle to tilt.

Action:

Replace the left and right rear axle air spring bellows.

Affected
Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information).
