| 2061288/4 | 2021-10-06. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Various and/or numerous Transmission control module DTCs logged - V8 Kovomo engine. Customer statement: Drive system fault active on DIP. Workshop findings: Various and/or numerous Transmission control module DTCs logged. Technical background: Loose pins within the transmission link harness to the Mechatronic unit for dual clutch gearbox -J743- connections can lead to various and/or numerous Transmission control module DTCs being logged. Carry out the checks within the Measure section of this TPI noting the following: The steps within the Measure section are applicable to vehicles specified with or without the Otto Particulate Filter (OPF) also referred to as the Gasoline Particulate Filter (GPF) NOTE: OPF/GPF fitment is Region specific. Should any issues be evident and the vehicle is specified with (OPF/GPF) The operative should check to confirm if EB89 (SC21/08 is required) and conduct if applicable.

| 2060596/3 | 2021-10-06. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING. Transmission DTC - U040100 50273/C461 Invalid Data Received From ECM/PCM "A" Customer statement / workshop findings: Diagnostic Trouble Code (DTC) U040100 50273/C461 Invalid Data Received From ECM/PCM "A" stored within the Transmission Control Unit. Technical background: During Adaptive Cruise Control (ACC) brake to stop events, it is possible for the brake pressure to decay at a rate outside of specified parameters, DTC - U040100 50273/C461 Invalid Data Received From ECM/PCM "A" will therefore be stored within the Transmission Control Unit. |
| 2052092/5 | 2021-10-05. Service bulletin. STRUCTURE; LATCHES/LOCKS/LINKAGES; ELECTRICAL SYSTEM. New Continental GT - Door soft close functionality. Customer statement / workshop findings Correct functionality and restrictions of the door soft close system need to be understood to prevent unnecessary customer complaints. Correct operation/function restrictions: The soft close feature is designed to minimalize effort when closing the door. This feature operates automatically. If a door is closed with insufficient force to engage fully, i.e. the door is only closed to the first catch position, the feature will automatically motor the door fully closed. Soft close operation works as per any other motor system. If you work or stress the motor whilst mid-operation the motor could stop working until it is reset (i.e. if you shut the door and re-open it before the soft close has fully engaged into position). If the door is operated over 40 times in less than 10 minutes, soft close operation will be deactivated for the next 10 minutes. If the soft close system does stop functioning through customer misuse, there may be a DTC code stored in the memory, the fault will be active until the ignition is cycled. The DTC will be logged in the relevant door control module memory but will not inhibit the door operation and can be ignored. The DTC will read B122D29: Lock unit for central locking, Implausible signal. |
| 2051712/6 | 2021-10-05. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ELECTRICAL SYSTEM; STRUCTURE. New Continental GT 48V anti-roll bar cable routing.

Measure: The 48 volt supply cable (1 ) to the anti-roll bar may appear to be trapped between the front subframe and the engine undersheet (arrows). See Figure 1. This would be visible on the LH underside of the vehicle and is the normal condition for this routing of cable. Do NOT raise a DISS technical query for this concern. |
| 2053170/7 | 2021-10-05. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Gear shift optimisation procedure - W12 TSI only. Customer statement / workshop findings: Customer reporting dissatisfaction with transmission shift quality in various driving conditions Prior to starting the instructions within this TPI, the Retailer must check and confirm the vehicle is in standard factory condition and has not had any non-approved aftermarket modifications conducted including the modification of the engine control modules (chip tuning) Should any aftermarket modifications be found, the Retailer must make Product Support aware by raising a DISS query to report the details of the modification, you must then await feedback from Product Support before conducting any further repairs relating to the shift quality complaint.
