3 Bulletin #: 2100 Advanced Technical Information Part ID: 3734 971 – Rough PDK II Operation during Adaption Phase Vehicles Affected Models Model Year Model Type VIN Range Vehicle-Specific Equipment Panamera As of 2017 up to 2021 971 (all 97A model variants) N/A N/A Revision History Revision Release Date Changes 0 January 21, 2021 Original document Condition Rough gear changes with unmatched engine and transmission revolutions further characterized by: • Brief engine surges in response without full engagement in the transmission • Engine temperature approaching or at operating temperature (50 – 100°C) • Low vehicle mileage (0 – 200 miles) • DME + PDK II programming performed recently, within 200 miles Technical Background The aforementioned conditions may result from a transmission that is undergoing adaption. There are numerous pre-requisite operations for successful operations of the PDKII. Examples of such operations include: touch- point adaptions; torque-fill timing, frictional coefficient adaption, control-valve mapping adaptions, and pressure sensor comparison among numerous others. Reprogramming the PDKII necessitates an adaptation. Therefore, programming should only be conducted when necessary. The following information describes the operating parameters necessary for key adaptions to occur. AfterSales January 21, 2021 Page 1 of 3 Bulletin #: 2100 Advanced Technical Information Part ID: 3734 3 Service Information If it is suspected the PDK II requires adaption, then please observe the following conditions during adaption: • Touch-point adaption and torque-fill timing Final Drive Oil Temperature > 45°C and < 110°C Operation of the transmission from 4th to 8th gear Ideally, driving is to be completed under constant driving conditions by changing gears between engine speeds of 1600 – 2000 rpm • Frictional Coefficient adaption Automatic Transmission Fluid (ATF) Temperature > 65°C and < 95°C These adaptions occur with every upshift conducted under load Adaptions also occur in Launch Control and the temperature behavior thereof • Control-valve mapping adaptions No temperature range limits. Occur during every clutch engagement operation The driving profile most directly determines the driving distance required by the PDK II to adapt successfully. Following the instructions above coupled with varying driving profiles, will allow the PDK II to adapt within approximately 125 miles (200 km). Driving only short trips, by which operating temperatures remain low relative to those referenced above, will significantly increase the distance required for adaption. Furthermore, adaption attempts should occur over longer distances and launches avoided. Warranty As always, please document the case completely in PQIS. For this repair, please code the “cause” as follows: Cause location: 37340 “Double clutch transmission” Cause symptom: 1126 “Jerky gear change” Use the following troubleshooting labor operation: 03350000 On board diagnostic (Main work) Fault memory read out 03350053 On board diagnostic (Composite) VAL AfterSales January 21, 2021 Page 2 of 3 Bulletin #: 2100 Advanced Technical Information Part ID: 3734 3 Search Items PDK II, Transmission, Clunky, Jerks, Gear change, Adaption Important Notice: Technical Bulletins issued by Porsche Cars North America, Inc. are intended only for use by professional automotive technicians who have attended Porsche service training courses. They are written to inform those technicians of conditions that may occur on some Porsche vehicles, or to provide information that could assist in the proper servicing of a vehicle. Porsche special tools may be necessary in order to perform certain operations identified in these bulletins. Use of tools and procedures other than those Porsche recommends in these bulletins may be detrimental to the safe operation of your vehicle, and may endanger the people working on it. Properly trained Porsche technicians have the equipment, tools, safety instructions, and know-how to do the job properly and safely. Part numbers listed in these bulletins are for reference only.
