An official CAA Japan notice concerns Passenger Cars (Porsche Panamera 4S and Others) - Repair. Due to a defect in the engine (camshaft controller). ■Defective component (part name): Engine (camshaft controller). ■Condition of the structure, equipment, or performance deemed noncompliant with standards, and its cause: In the engine's camshaft controller, an inappropriate design value for the head thickness of the bolts securing the cam gear has caused some bolts to be damaged during tightening. As a result, the cam gear may become loose, causing abnormal noise or engine malfunction due to incorrect ignition timing. Continued use in this condition may, in the worst case, cause the cam gear to become unsecured, resulting in engine stalling and inability to restart. Published 2015-03-31.
What to do now
(Recall)外-2144 ■Corrective measures: On all vehicles, replace the camshaft controller's cam gear securing bolts with improved parts. If any bolts have loosened, replace the affected camshaft controller with an improved part. If any bolts have broken, inspect the engine internally and perform the necessary repairs.
