122-Z4H5Q-052018-05-21. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. There are two potential issues related to PASM Control units in the Panamera (971) for which an updated part has been released. One may be experienced by the customer and the other by the workshop. 1. If programming is interrupted while performing the WH29 service action, the control unit may become unresponsive and cannot be communicated with or reprogrammed.
122-L6U2W-042018-04-23. Service bulletin. ELECTRICAL SYSTEM. Subject: Plug socket (230 V/100 V/110 V) Symptom: AC plug socket (230 V/100 V/110 V) does not work. Cause: The bit for "Plug socket switch-off" may be set unnecessarily in the gateway control unit.
122-G6X5S-042018-04-23. Service bulletin. ELECTRICAL SYSTEM. Subject: Control unit for high-voltage charger Information: Due to a software error, there is a possibility that the control unit for the high-voltage charger will not switch to energy-savingmode after the vehicle is stopped in the event of specific user behavior. This can result in an increased closed-circuit current load and can thus deplete the vehicle electrical system battery.
122-L4K3P-032018-03-13. Service bulletin. LANE DEPARTURE: SENSING SYSTEM: CAMERA; FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA; ELECTRICAL SYSTEM; BACK OVER PREVENTION: SENSING SYSTEM: CAMERA. 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-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.
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-R3R8W-122017-12-14. Service bulletin. ELECTRICAL SYSTEM. Technical Concern: The technician confirms the customer's observation and also notes fault code P305400 stored in the DME.
122-L4R6B-122017-12-14. Service bulletin. ELECTRICAL SYSTEM. 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.
122-U8W5W-122017-12-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Subject: Gateway control unit Information: Due to a software error, the sports exhaust system can remain activated after switching the ignition off and on again although it is shown as inactive in the Vehicle menu. Remedial action: Re-code gateway control unit
122-D2C2G-112017-12-14. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Technical Concern: This failure is the result of faulty message monitoring within the instrument cluster. Because the instrument cluster cannot properly detect and display the current cruise control status, the cruise control does not engage. Service Information: The recommended repair is to replace the instrument cluster. Only part numbers with suffix "G" or later should be used.
122-E5M8Q-112017-12-14. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Technical Concern: This failure is often accompanied by a long list of instrument cluster faults, including "C11011 - Control unit faulty, watchdog".
