Tools
Technical values
General information
Symptom
On vehicles with powerlift for rear lid (I-no. 4E7), the drive mechanism can be reversed or operate loudly when closing when there is no visible resistance from an obstacle.
Cause, date of introduction and remedial action
Cause
The powerlift drive mechanism can be reversed due to bodyshell and manufacturing tolerances.
Date of introduction
The production process was changed for vehicles produced after 08.09.2010.
Remedial action
Check the vehicle history to see if the vehicle is affected by workshop campaign WA67 and whether the campaign has already been completed.
The tailgate control unit is also re-programmed as part of workshop campaign WA67. No other measures are required.
In the case of vehicles manufactured before the specified date of introduction but not affected by workshop campaign WA67, the tailgate control unit must be re-programmed using PIWIS Tester II if complaints are received.
