  Information
  
  If there are still fault memory entries in individual control units, start the engine briefly and then switch it off again. Wait for approx. 10 seconds before switching the ignition on again and re-establish the connection between the PIWIS Tester and the vehicle. Then read out and erase the fault memories of the affected control units again separately.
  
  If the control units are found to have other faults, which cannot be erased and are not caused by control unit programming , these faults must be found and corrected.
3. Switch off ignition.
4. Disconnect the PIWIS Tester from the vehicle.
5. Switch off and disconnect the battery charger.
6. On vehicles with Porsche Entry & Drive, replace the original driver's key in the ignition lock with the control panel again.
