Refer to → Wiring diagrams, Troubleshooting & Component locations. The battery test for these vehicles is performed during "Guided Fault Finding".
  • If the battery test is not possible with "Guided Fault Finding" due to a partially or exhaustively discharged battery, the battery can be quickly evaluated with the help of the "battery test via current draw".
  • Maintenance-free batteries must not be opened. Otherwise, the warranty is voided.

  Caution

It is not possible to check the battery using "Guided Fault Finding" through MY 2010 during the following procedure, even if the vehicle has a Battery Monitoring Control Module -J367-:

  • A3 from MY 2004 (8P)
  • TT from MY 2007 (8J)
  • R8 from My 2007 (42)
