Vehicles with assigned scope 2:
Due to currently reported cases, the re-coding of the instrument cluster cannot be performed successfully in some
cases.
For this reason, it is recommended to not carry out the workshop campaign on vehicles with scope 2 temporarily.
Until further notice, no appointments should be made with the customer to carry out the re-coding of the instrument
cluster.
A remedial measure is currently in elaboration.
We will inform you about the availability of the remedial measure as soon as possible.
For vehicles that are assigned to scope 1, the customer letters can still be sent.
Please forward this information to your dealers.

 Overview

WKA0 Workshop campaign with customer letter "Sending customer
letter and re-coding instrument cluster if necessary"
Overview

For the 911 GT2 RS and 911 GT3 RS models from model year 2015 onwards, race track tires that are approved for use on
public roads (e.g. Michelin Pilot Sport Cup 2 R tires) are available from the a ermarket. These require higher tire pressure
than standard tyres.
If the tire pressure is too low, this can cause tire damage in the form of noises and tread separation while driving.

To prevent this, a customer letter must be sent to customers informing them that the tire pressure must be increased
when tting race track tires. Depending on the date of manufacture of the vehicle, the instrument cluster may also have to
be re-coded so that the tire type - 20" track - can be selected in the "TPM" menu and the tire pressure is monitored
correctly by the Tire Pressure Monitoring (TPM) system. A Driver's Manual Supplement containing the technical values for
the tire pressures will only be available at a later date. As soon as it becomes available, this Supplement will have to be
handed over to customers during a separate campaign.
To nd out which work needs to be done on each vehicle, the vehicles are assigned di erent campaign scopes.
For more information, see PIWIS Vehicle Information.
