WE12 - Replacing Vacuum Line For Exhaust Flaps (Workshop Campaign)
Revision:
March 11, 2015
This revision amends WE12 as follows:
1. Under Parts Info “Information” note added and a new part number for Vacuum line.
2. Under Affected Vehicles — The North American affected vehicle total was changed from 7,146 to
1,470.
3. Under Attachment “A” — Work Procedure Step 7 is new information.
4. Under Attachment “A” — Work Procedure Step 8 (previous Step 7) has been revised and includes the
new vacuum line part number 000.043.209.86.
5. Under Attachment “B” — Claim Submission the “Parts required” has been changed to new vacuum line
part number 000.043.209.86.
Model Year:
As of 2012 up to 2014
Vehicle Type:
911 Carrera S (991)/911 Carrera 4S (991)
Concerns:
Vacuum line for exhaust flaps
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The vacuum
line for the exhaust flaps can shorten because of the heat from the engine and become
detached from the vacuum units for the exhaust flaps over the service life of the vehicle.
As a result, there is no guarantee that the exhaust flaps and other vacuum-controlled actuators on the
engine will function correctly. This causes the warning message "Fault cooling system" to be displayed in
the instrument cluster.
Action
Required:
Replace vacuum line for exhaust flaps.
Affected
Vehicles:
The VIN(s) can be checked by using PIWIS Vehicle Information link to verify if the campaign affects the
vehicle. This campaign is scope specific to the VIN! Failure to verify in PIWIS may result in an improper
repair. This campaign affects 7,146 vehicles in North America.

Parts Info:
Information
A modified vacuum line for exhaust flaps is available with immediate effect.
This modified vacuum line further improves the routing of the line to prevent it from slipping off the
exhaust flaps.
Only the new vacuum line specified below must therefore be used from now on for carrying out this
campaign.
This measure does not have to be carried out again on vehicles on which the vacuum line has already
been replaced as part of this campaign.
NOTE: DO NOT ORDER PARTS. THEY WILL BE AUTOMATICALLY ALLOCATED FOR UP TO 50% OF THE
VEHICLES THAT ARE SERVICED AT YOUR DEALERSHIP. ONCE YOUR DEALERSHIP IS OUT OF STOCK AND
REQUIRES ADDITIONAL PARTS, YOU SHOULD SUBMIT A PTEC/PAV.
