ANA1 - Check Chassis Settings on the Rear Axle and Correct Them if Necessary (Recall
Campaign)
Revision:

This bulletin replaces bulletin Group 4 10/22 ANA1, dated February 18, 2022.

Model Year:

As of 2021 up to 2022

Model Line:

Cayenne (9YA)/Cayenne Coupé (9YB)

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.

Check tires using the test table 1

[Scope 1 or 4]

Check condition of tires

Check tires
Measuring method
Differential wear:
Measure tread depth as in Fig.
 Check tires -Arrows- across
all main tread grooves per tire
rear axle (inside to outside), and
between the driver and passenger
side of the rear axle  then create
max. difference

Tread depth:
Measuring tread depth over
all main profile grooves 
take minimum value

Shoulder wear:
Visual inspection of the inner
and outer shoulders of the
rear-axle tires

≥4mm/ 0.157 in (summer)

Visual inspection as per
sample photos

≥5mm/ 0.197 in (M&S)

≤ 2 mm/ 0.078 in

If the result of the check is not correct (initial alignment) and if the tire needs to be replaced, all wheel
sets that have been used in the vehicle since the time the campaign AMA9 was carried out must
be checked. 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. See information: 
