Service bulletins for the 2015 Porsche 918

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-A7C8T-102018-10-15. Service bulletin. SUSPENSION:FRONT:CONTROL ARM. Informatin: Internal tests have shown that the longitudinal and transverse control arms installed on the affected vehicles may be prone to corrosion. The durability of these components cannot therefore be unequivocally guaranteed.
122-B9V4V-062018-06-25. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Information: The Approval and Support Management system was created to offer assistance to the dealer organization with new and complex technical issues by utilizing the Support Specialists within Porsche R&D. As a result, this process has reduced vehicle downtime and repeat repairs substantially.
122-A8U3D-052018-05-21. Service bulletin. ENGINE AND ENGINE COOLING; SUSPENSION:REAR; EQUIPMENT. Condition Loose or Damaged M8 Threaded Inserts Technical Background The protective panel below the engine is actually an integral part of the rear CFRP monocoque. The rear suspension must never be ladened without this panel properly installed and at least the eight M8 fasteners installed and tightened to specification (see Figure 1).
122-R7X7L-012018-01-29. Service bulletin. ENGINE. Symptom: Vehicle jerking while driving using the combustion engine. Cause: If the vehicle is driven continuously in the high-load range (e.g. race track driving), vibrations can damage the connector contacts on the intake manifold pressure sensors.
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-S2Z5A-122017-12-14. Service bulletin. TIRES. Information: Summary tables with applicable notes on Ultra High Performance (UHP) tires for easy reference is supplied in this bulletin.
122-R3Z9M-122017-12-14. Service bulletin. STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS. Subject: Corrosion on underbody panelling screws Information: Traces of corrosionmay be visible close to the fastening screws due to thematerial pairing. Remedial Action: Rework screws on underbody panelling.
122-E4S9A-042017-10-15. Service bulletin. SUSPENSION; POWER TRAIN:AXLE ASSEMBLY. During hard cornering maneuvers, a rhythmic clicking noise may be emitted from the rear axle hubs. This noise is a non-hazardous, non-destructive characteristic of the vehicle. The root cause is the relative movement of the wheel and brake rotor against the 5 drive pins of wheel hub. This tiny amount of movement produces vibrations that are propagated through the rigid suspension joints and carbon fiber reinforced structure of the vehicle. Improper wheel nut tightening or trace amounts of lubricants, debris and corrosion between the hub, brake rotor and wheel all can facilitate this movement. Procedure: If the clicking sound becomes unacceptable to the customer, repair actions may be attempted that may provide at least a temporary solution. These should be implemented in two successive scopes depending on severity and reoccurrence.
