ANA1 – Rear Axle May Be Misaligned – 2021-2022 Porsche Cayenne

SEOCONTENT-START

Technical Information Service 10/22 ENU ANA1 4 ANA1 – Check Chassis Settings on the Rear Axle and Correct Them if Necessary (Recall Campaign) Model Line: Cayenne (9YA)/Cayenne Coupé (9YB) Model Year: As of 2021 up to 2022 Concerns: Suspension alignment Information: During a data analysis with regard to carrying out recall campaign AMA9, we discovered that the chassis geometry on the rear axle has deviated in some cases. This faulty chassis setup can cause tire wear on the rear axle on vehicles with higher mileage. As a result, the high-speed stability cannot be guaranteed at high vehicle speeds. Action required: Adjust vehicle measurements if necessary. Affected Vehicles: Only vehicles assigned to the campaign (see also PCSS Vehicle Information). Required tools Tools: • 9229/1 – Puller hook • T10188 – Insert tool • VAS 6826 Steering wheel scales • VAS 6918 Quick-clamping unit • 9900 – PIWIS Tester 3 • Wheel alignment machine, e.g. VAS 6292 Porsche Approved Alignment Machine • Torque wrench, 40 – 200 Nm, e.g. VAG 1332 Torque wrench, 40 – 200 Nm Check chassis settings on the rear axle and correct them if necessary Work procedure: 1 Measure the vehicle according to  Workshop Manual ‘449503 Measuring vehicle at the front and rear’ (initial measurement). Information If suspension alignment work is subcontracted to a service provider, it is important to ensure that the service provider is provided with the correct adjustment values or that these adjustment values are supplied in writing with the vehicle.

For regions with a winter season and for the use of winter tires (M&S), the second set of wheels must be checked in accordance with the table if available and the affected tires must be replaced. • Document the tire wear by taking photos. The images must be documented so that the wheel position and rolling direction of the tire are clearly visible. • Upload the images to the PCCS quality line with the relevant description on the affected side, e.g. rear left tires_VIN_Figure 1. • Replace the affected tires and invoice them using a reimbursement claim.

The tire makes approved by Porsche AG with the corresponding N-marking must be used. The same tire make with the same Nmarking on the front and rear axle must also be used. 2 Enter the campaign in the Guarantee and Maintenance booklet. Warranty processing General information on warranty processing The scopes for this measure include only the alignment and check adjustment of the chassis geometry, including tires. In the event of uneven tire wear, further work and the additional parts and working times required for replacing the tires are not included in the scope and must be recorded afterwards.
