122-S4R2X-072018-07-30. Service bulletin. ELECTRICAL SYSTEM:WIRING. Subject: Outside temperature sensor Symptom: The outside temperature display shows implausible values. Cause: The outside temperature display can show implausible values because the wire harness for the outside temperature sensor is too long.
122-F4U4P-042018-04-23. Service bulletin. ELECTRICAL SYSTEM. Model Line: Cayenne (92A) Macan (95B) Concerns: AGM starter battery (referred to below simply as ?battery?) Situation: Customer complaints concerning battery-related topics Recurring customer complaints concerning topics relating to battery capacity and quality.
122-S7H6V-032018-03-13. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Concerns: Battery trickle charging with "Charge-o-mat"may time out within a short period of time. The trickle charging will thus end prematurely. Thismay result in a dead battery. Information: The ?Charge-o-mat? device recommended by Porsche can be connected to the plug socket in the above-mentioned vehicles again in accordance with instructions in order to trickle-charge the battery (e.g. in the showroom) if: ? the gateway control unit is re-coded beforehand using the PIWIS Tester with test software version 36.800.030 installed.
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-X5B2V-102017-11-08. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Due to incorrect fitting of the front hood lock cable, there is a possibility that the cable will rub against the microswitch for the hood lock. This will damage the microswitch. As a result, the warning "Hood open" will be displayed in the instrument cluster.
122-B2R3T-102017-11-08. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. There is increased friction in the air spring compressor valves at temperatures below ?13° F (?25° C). This can result in a situation in which the maximum control current is not sufficient to actuate the valves. As a result, a warning message will be displayed in the instrument cluster and Porsche Active Suspension Management (PASM) will stop working temporarily. Re-program PASM control unit using the PIWIS Tester with software version 33.010.030 (PIWIS Tester 3) or version 17.100.030 (PIWIS Tester II) or a higher software version installed.
122-L6F9K-072017-10-27. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. If the software versions are no longer compatible, it may no longer be possible for the DME control unit to communicate with the instrument cluster via the gateway control unit.
122-Y8E4C-102017-10-15. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Subject: Outside temperature display in the instrument cluster Information: Customers complain that the outside temperature value in the instrument cluster is implausible and does not change.
122-B3Y9V-102017-10-15. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Concern: Coding failures of the instrument cluster. Information: Ensure the Auto Memory option is deselected prior to replacing or coding an Instrument Cluster on all Macan models. Due to the numerous options and software available to support those options, coding faults can occur. To turn off Auto Memory through the Instrument Cluster; Select Setting-> Locking-> Auto Memory. If the vehicle is not equipped with Auto Memory, no work around is necessary.
122-A4N7P-092017-09-14. Service bulletin. TRAILER HITCHES; ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL.
