Work Procedure 3
Remedial action and repair measures in the event of complaints relating to comfort and noiseWork Procedure: 3
3. Remedial action and repair measures in the event of complaints relating to comfort (gearshift and drive-off quality).
3.1 Create and save the Vehicle Analysis Log (VAL) using the PIWIS Tester.
3.2 Find and correct any faults that are present in other control units (DME, PSM, air conditioning, etc.).
3.3 Check oil level in PDK transmission and correct it if necessary --> 370235 Checking and topping up ATF.
3.4 Teach the throttle valve using the PIWIS Tester:
Select PIWIS Tester II > DME control unit >> "Maintenance/repairs" menu >>> menu item "Adaptations" >>>> "Throttle valve adaptation" function. Follow the instructions on the PIWIS Tester.
3.5 Perform engine torque loss adaptation.
Conditions/procedure for engine torque loss adaptation:
^ Engine temperature is at least 176°F. (80°C.) (read out the temperature from the PDK control unit by selecting "Actual values/Input signals" > "CAN input signals - Engine temperature").
^ All loads switched off.
^ PDK selector lever in position P.
^ Allow engine to run at idle speed for 3 minutes with air conditioning switched off.
^ Then allow engine to run at idle speed for 3 minutes with air conditioning switched on.
^ Switch off ignition and wait 15 seconds (adaptation values are stored).
3.6 Create and save the Vehicle Analysis Log (VAL) using the PIWIS Tester.
3.7 Perform adaptation drive.
WARNING
Driver steers off course during adaptation drive
^ Increased risk of accidents
^ Danger to other people on the roads
--> Get another person to accompany the driver and give him the relevant instructions for carrying out the adaptation drive.
--> Only drive the vehicle to achieve the rpm and speed ranges required for the adaptation drive in accordance with road traffic regulations and if the road, weather and traffic conditions are conducive to such driving.
Observe and meet the following conditions for the adaptation drive:
^ Transmission fluid temperature is > 140°F. (60°C.) (read out the temperature from the PDK control unit by selecting "Actual values/Input signals" > "CAN output signals - Transmission sump temperature").
^ Perform adaptation drive on a level stretch of road.
^ Once the transmission fluid temperature is > 140°F. (60°C.), switch off the engine and ignition and wait at least 20 seconds.
^ Switch on ignition, wait at least three seconds and then start the engine.
^ After you have switched the ignition off and then on again, there should be no error messages displayed in the instrument cluster.
^ Perform adaptation drive in shift program "M".
3.7.1 Start the adaptation drive, accelerate to rpm range 1,000 - 1,200 rpm in 5th gear and maintain this range for two minutes.
3.7.2 Then change gear several times (in any target gear) and switch between traction and deceleration mode while driving in the selected gears.
3.7.3 Then, change to 5th gear again and repeat steps 3.7.1 to 3.7.3 twice. The procedure must be done three times in total.
3.7.4 Continue the adaptation drive, accelerate to rpm range 1,000 - 1,200 rpm in 6th gear and maintain this range for two minutes.
3.7.5 Then change gear several times (in any target gear) and switch between traction and deceleration mode while driving in the selected gears.
3.7.6 Then, change to 6th gear again and repeat steps 3.7.4 to 3.7.6 twice. (The procedure must be carried out three times in total.)
3.7.7 Stop the vehicle, switch off the engine and ignition and wait at least 20 seconds.
3.7.8 Switch on ignition, wait at least three seconds and then start the engine.
There should be no error messages displayed in the instrument cluster.
3.7.9 Carry out adaptation drive once more as described in steps 3.7.1 to 3.7.6.
3.7.10 Stop the vehicle, switch off the engine and ignition and wait at least 20 seconds.
3.7.11 Switch on ignition, wait at least three seconds and then start the engine.
There should be no error messages displayed in the instrument cluster.
3.7.12 Continue the adaptation drive, accelerate to rpm range 2,000 - 2,500 rpm in 5th gear and maintain this range for two minutes.
3.7.13 Then change gear several times (in any target gear) and switch between traction and deceleration mode while driving in the selected gears.
3.7.14 Then, change to 5th gear again and repeat steps 3.7.12 to 3.7.14 twice. The procedure must be carried out three times in total.
3.7.15 Continue the adaptation drive, accelerate to rpm range 2,000 - 2,500 rpm in 6th gear and maintain this range for two minutes.
3.7.16 Then change gear several times (in any target gear) and switch between traction and deceleration mode while driving in the selected gears.
3.7.17 Then, change to 6th gear again and repeat steps 3.7.15 to 3.7.17 twice. (The procedure must be carried out three times in total.)
3.7.18 Stop the vehicle, switch off the engine and ignition and wait at least 20 seconds.
3.7.19 Switch on ignition, wait at least three seconds and then start the engine.
There should be no error messages displayed in the instrument cluster.
3.7.20 Carry out adaptation drive once more as described in steps 3.7.12 to 3.7.17.
3.7.21 Stop the vehicle, switch off the engine and ignition and wait at least 20 seconds.
3.7.22 Switch on ignition, wait at least three seconds and then start the engine.
3.7.23 End the adaptation drive.
3.7.24 Create and save the Vehicle Analysis Log (VAL) using the PIWIS Tester.
3.7.25 Leave the vehicle overnight if necessary and evaluate it again with regard to gearshift/drive-off quality the next day.
^ If the vehicle checks out OK with regard to gearshift/drive-off quality --> End of remedial action.
^ If the vehicle does not show any improvement with regard to gearshift/drive-off quality, please contact Porsche to find out what to do next.
