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-A7E7V-032018-03-13. Service bulletin. EQUIPMENT. Customer Concern: The remote key battery is dead before its expected end of life. Technical Concern: The technician confirms this behavior. Service Information: For vehicles built before 8/19/2017, the key itself is defective and the battery likely performs as expected. In this case, replace the key.

There is a possibility that the front camera heater on the affected vehicles will be switched on more often than required at low temperatures due to incorrect coding. This can result in material fatigue over the service life of the vehicle and the front camera can stop working. As a result, the "Camera system fault" warning will be displayed in the instrument cluster and camera-based assistance systems, such as lane departure warning, pedestrian warning, traffic sign recognition and Full beam assist will fail. Remedial Action: Re-code front camera control unit.
122-S3R9K-032018-03-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Change of supplier for the heat shields for the catalytic converter and oxygen sensors from "Thermamax" to "ISOLITE". If a heat shield needs to be replaced, the existing type of heat shield must be determined before doing any other work. If the heat shield to be replaced is a "Thermamax" heat shield, the entire set (all related heat shields) must also be replaced.
122-W2Q5L-022018-02-12. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Customer Concern: The customer may desire a PCM software update. Perhaps the customer experiences an unwanted PCM behavior and errantly believes a PCM software update will help solve the perceived issue. Technical Concern: The calendar year 2017 software update for PCM4.1 is not compatible with MY17 Panamera (971) (which does have PCM4.1). In fact, this software update may make the PCM climate controls permanently inoperable.
122-G2H3D-022018-02-12. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Concern: Incorrect Model Year (MY) coding in Gateway prevents programming Information: During software updates, it is possible for the Gateway to store an incorrect MY. If this happens, the vehicle will function as normal until the next attempt at Coding/Programming.
122-D5Y9E-022018-02-12. Service bulletin. ELECTRICAL SYSTEM. Customer Concern: There are reports of failed Porsche Car Connect (PCC) initializations. Technical Concern: Due to input handling in the VTS software, the Porsche Car Connect initialization fails. The ninth character in the VIN may be an ?X? (e.g. WP0AF2A7XHL123456). However, the system sees this ?X? character as invalid and does not transmit the installation code to the backend server. In this case, the initialization ends unsuccessfully. Additionally, the PCC portal does not register the failed attempt.
