122-M3B5L-032018-03-13. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE). 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-storey car park 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.
122-K3Z4P-022018-02-12. Service bulletin. ENGINE. Subject: Fastening screws for camshaft controllers Information: Due to influencing factors during the camshaft controller assembly process, the threaded connections can become strained to such an extent that the function of the camshaft controller cannot be guaranteed over the service life of the vehicle. Remedial action: ? Replace fastening screws for camshaft controllers. ? Also replace one or both camshaft controllers if necessary.
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-N6B7V-122017-12-14. Service bulletin. STEERING. 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 symptom must 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. * On a straight stretch * from speeds 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.
