If you drive a Porsche Cayenne produced between November 30 2006 and January 18 2008, please pay a visit to your service center. A total of 18,856 Porsche Cayenne SUVs manufactured during the period needs to have their fuel line rearranged as there is a possibility of slight movements of the engine when traveling causing the fuel line to come in contact with the engine compartment cladding. This causes a knocking sound and in some cases abrasion markings on the fuel line.
Out of 5 complaints of knocking sounds worldwide, there was one case of abrasion markings. As a preventive measure, Porsche has decided to modify the fuel line layout of the vehicles. The procedure is free of charge and will take an estimated 40 minutes. Customers that are affected will be advised.
