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-J4H9M-122017-12-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE. Situation: Cayenne Diesel vehicles were equipped with undisclosed Auxiliary Emission Control Devices which are not permitted by emissions regulations.

122-E3D6M-122017-10-25. Service bulletin. ELECTRICAL SYSTEM. Due to incorrect sealing of the electric plug connection on the transfer case servo motor, moisture can get into the connector. As a result, the contacts can become corroded. In the event of a customer complaint, check the plug connection on the servo motor and the servo motor itself for damage: ? If the electric plug connection on the transfer case servo motor is corroded, replace section of cable including electric plug connection using a repair kit. ? If the servo motor is damaged, replace section of cable including electric plug connection and transfer case servo motor.
122-Q3V5G-102017-10-15. Service bulletin. ELECTRICAL SYSTEM. Cause: Clicking noises can come from around the transfer case when manoeuvring the vehicle (or driving slowly) due to activation of the transfer case servo motor. Remedial Action: Before doing any other work, the symptommust be simulated using a test procedure. (Opening the door windows can be helpful when evaluating noises). 1 Conditions for the first test procedure: ? Activate the Start/Stop function and ? deactivate all sources of noise in the vehicle (Entertainment, ventilation, etc.). ? A multi-story parking garage can be useful for acoustic reverberation. ? Onastraight stretch ? fromspeeds less than 10mph (20 km/h) ? brake the vehicle to a standstill. ? The best way of finding the clicking noise is by driving slowly and then stopping the vehicle.
