Check that the vacuum line is seated correctly at the control box.
This bulletin applies to all 2017 Porsche models. The warning message “Fault cooling system, visit workshop” may appear in the instrument cluster.
There is also the possibility that the sport exhaust system cannot be activated. The cause may be due to the vacuum line slipping off of the control box as a result of component tolerances of the clamp.
In the event of a customer complaint, check that the vacuum line is fitted securely on the right and left of the control box. If the vacuum line has slipped off, the electric change-over valve can be contaminated by drawing in dirt. Replace the electric change-over valve and replace the vacuum line using a new line and new clamp.
