Procedure 3
Procedure: 33 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 both oil levels (clutch and transmission) and correct them if necessary --> 370235 Checking and topping up ATF (clutch fluid) and --> 399035 Checking and topping up oil for final drive (with transmission oil).
Information
If implausible test results are obtained (e.g. clutch fluid level too low and transmission oil level too high) and/or if fault memory entries are present in the PDK control unit, these faults must first be found and corrected as shown in the relevant flow chart.
3.4 Determine/clarify the exact problem.
When driving off while the engine is cold, there is first a delay and then power is transmitted with a hard slap (does not concern turbo vehicles). Is this the problem?
If it is: --> Step 3.4.1
If not: --> Step 3.4.2
3.4.1 Read out the data version of the PDK control unit under "Extended identification".
Is the data version index 44 (or higher) for the Porsche software part number (e.g. 997.618.375.44)?
If it is: --> Step 3.5
If not: --> Perform DME and PDK data version update using the PIWIS Tester II V9.300 (or higher:
PIWIS Tester > "(Control unit) Programming in the event of customer complaint" >> "Customer complaint 1".
--> Continue with Step 3.5
3.4.2 Other complaints relating to comfort (gearshift and drive-off quality)
Read out the data version of the PDK control unit (PIWIS Tester > PDK control unit >> Identification menu item).
If the PDK data version is < "T082" --> Re-program the DME and PDK control unit using the PIWIS Tester II and software versions 5.200 (or higher). Then continue with Step 3.5. If the PDK data version is >= "T082" --> Continue with Step 3.5.
3.5 Teach the throttle valve using the PIWIS Tester:
Select PIWIS Tester > DME control unit >> menu item "System adaptation" >>> "Throttle valve adaptation" function.
3.6 Perform engine torque loss adaptation.
Conditions/procedure for engine torque loss adaptation:
^ Engine temperature is at least 80°C.
^ 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 (high load).
^ Switch off ignition and wait 15 seconds (adaptation values are stored).
3.7 Calibrate PDK by carrying out minor calibration routine ("Calibration without previous part replacement"):
Select PIWIS Tester > PDK control unit >> menu item "Calibration" >>> "Calibration without previous part replacement" function.
3.8 Create and save the Vehicle Analysis Log (VAL) using the PIWIS Tester.
3.9 Perform adaptation drive. During the adaptation drive, change gear at least 30 times initially (in "M" or "D").
3.10 Perform touchpoint adaptation.
Conditions/procedure for touchpoint adaptation:
^ At least 30 gear changes (in "M" or "D") were carried out previously while driving the vehicle.
^ Stop the vehicle on a level surface, but do not switch off the engine.
^ Position steering wheel straight ahead.
^ Do not switch any loads on or off.
^ Hold the vehicle for three minutes in transmission range "D" with the foot brake pressed firmly. Do not press the accelerator pedal.
^ Switch off ignition for at least 15 seconds (adaptation values are stored).
3.11 Continue the adaptation drive and again change gear at least 30 times (in "M" or "D").
3.12 Repeat touchpoint adaptation (Step 3.10) once.
3.13 Continue the adaptation drive using the gears and rev ranges specified below and observe any other specifications.
3.13.1 Accelerate to rev range 1,700 rpm in 5th gear. Maintain rev range 1,700 rpm - 3,000 rpm in 5th gear with a low operating load for three minutes.
3.13.2 Then, accelerate to rev range 1,700 rpm in 6th gear.
Maintain rev range 1,700 rpm - 3,000 rpm in 6th gear with a low operating load for three minutes.
3.14 End the adaptation drive.
3.15 Create and save the Vehicle Analysis Log (VAL) using the PIWIS Tester.
3.16 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 your importer to find out what to do next.
