WM 9X00IN Measurement Of Closed-Circuit Current (Except PANAMERA S Executive, PANAMERA 4 S Executive, PANAMERA Turbo Executive, PANAMERA GTS): Measurement

Read off the measured values after the waiting period specified in the table.

1. Switch on ignition for 10 seconds.
2. Switch off ignition.
3. Open the driver's door and close the rotary latch with a screwdriver while the door is open.
4. Lock the vehicle using the central-locking remote control and switch off passenger compartment monitoring (press the button on the remote control twice in one second).
5. Remove short circuit bridge.
6. Read off the closed-circuit current.

   Information 

   • If the value of the closed-circuit current is higher than the value determined in the table, the cause must be established systematically.
   • Recommended troubleshooting procedure: With the measuring device connected, remove the fuses of terminal 30 and the relays successively. Observe the values displayed on the measuring device when removing the fuses and relays in order to detect a reduction in current.
   • The measured values can vary by approx. 20%.
   • The values listed in the table depend on the condition of the battery, the room temperature, the engine temperature and therefore should only be regarded as guidelines.

   Reading off the measuring range: 

   Read off the measuring range only after at least 35 minutes have passed since locking the vehicle.
