Service bulletins for the 2010 Porsche Panamera

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

122-A6Z3V-032018-03-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE). Subject: Intake valves and intake ports Information: Carboned-up valves in the engine can be reworked and cleaned using cleaning equipment. If there is a complaint about knocking combustion, e.g. during acceleration at high load, the condition of the intake valves and portsmust be checked before doing any other work. If the check shows that the intake valves and intake ports have carbon deposits and are dirty, they must be cleaned using the VAS 294 011 - cleaning unit. There should be no need to replace the components. Date of Introduction: The VAS 294 011 - cleaning unit can be ordered immediately for dealers. Remedial Action: The VAS 294 011 - cleaning unit is used for cleaning carboned-up intake valves and intake ports. Compressed air is used to spray a special granulatemixture into the intake port,where it loosens and removes carbon build-up. The dirty granulate is extracted during spraying using an industrial vacuum cleaner.

122-T7Y5Q-122017-12-14. Service bulletin. ELECTRICAL SYSTEM. Information: This document updates information previously published in EQ 1105, EQ 1105, and EQ 1401. To provide stable voltage and sufficient current throughout certain service operations, you should connect the vehicle to a battery charger (sometimes referred to as a power supply). However, you may experience ECU programming and coding issues if the chosen battery charger has insufficient power. Many workshop manuals currently advise use of a battery charger with a 40 or 70 A current rating. However, with the increasing current requirements of modern Porsche vehicles, we recommend a battery charger capable of producing a minimum current of 90 A.
122-Z3X2N-122017-12-14. Service bulletin. FUEL SYSTEM, GASOLINE. Information: FC00001E for right side rear lid strut is set in the Rear Lid Control Unit.

If moisture is suspected, check the lid thoroughly for leaks.
