Service bulletins for the 2014 Porsche Boxster

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-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-N9Z4L-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Concerns: AGM starter battery (referred to below simply as 'battery') Situation: Support for the care andmaintenance of the AGMstarter battery (at the dealership): From the time the vehicle is delivered to the Porsche Centre until it is handed over to the customer, the battery must be maintained and charged regularly, depending on use.
122-R7W2C-072017-10-27. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. 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-W4G8S-102017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. Technical Concern: By design, the vehicle gateway allows certain vehicle features to time-out, in stages. This allows the vehicle to sleep. One feature that can time-out is the 12 V DC power point (cigarette lighter) in the center console area. One of the recommended methods of using the battery maintainer is to plug the battery maintainer into this power point. If this power point becomes disabled, it will not allow current flow from the battery maintainer to the vehicle, the vehicle battery will not trickle charge, and the battery maintainer will eventually shut off.
122-B7U4T-052017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer Concern: Certain vehicle systems have unwanted, unpredictable behavior. Technical Concern: The symptoms are difficult to diagnose. There may be multiple symptoms intermittently affecting multiple systems. Though this is not an exhaustive list, some common failure modes are: ? Start/stop issues ? Power windows not fully returning to the parked position after automatic preopening ? PCM audio stopping during a start/stop cycle Ultimately, the technician determines that low 12-volt battery voltage is the underlying root cause of the unwanted behavior. The technician corrects the battery?s low voltage. Consequently, the unwanted behavior ends.
122-G7H3U-062017-09-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Concerns: Instrument cluster Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The following fault symptoms can occur on the affected vehicles due to a software error in the instrument cluster: * Failure of the display on the multi-function display: The display on the multi-function display in the instrument cluster can stop working at times under certain conditions. The display starts working again after a certain time. * Implausible service reminder indicator display: The driver is informed that a service (maintenance, intermediate maintenance or oil service) is due although the mileage and date for a required service have not yet been reached.
122-M6M5Z-062017-09-14. Service bulletin. ELECTRICAL SYSTEM:HORN. Concerns: Horn (also referred to as fanfare) Information: Modified assignment of connector contacts due to installation of new type of horn. As a result, if the horn needs to be replaced, an adapter cable must also be installed.
122-W6Q4V-062017-08-01. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:SOFTWARE. Concerns: PDK control unit Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. A shift rod movement at a shift gate that was not selected can be detected incorrectly on the affected vehicles due to a software error.
