Battery, Disconnecting and Connecting

Overview - Battery, Disconnecting and Connecting

Note the following when charging or using the battery jump start terminal on vehicles with the Start/Stop System: first connect the charge cable to the positive terminal and then connect the body ground. This ensures that the battery sensor is not bridged. Charging the battery directly on the ground terminal will bridge the battery sensor and the battery data will not be recognized by the sensor during the charging process. The values stored in the data bus on board diagnostic interface regarding the battery condition no longer match the values for the charged battery.

WARNING

Risk of injury. Pay attention to all warnings and safety precautions.

1. Battery Ground Cable Terminal Clamp
   • Pay attention to the information regarding the threaded connection for the battery terminals.
   • In vehicles with a Start/Stop System, the Battery Monitoring Control Module -J367- (battery sensor) is additionally installed here. Observe the instructions.
2. Ground Cable Battery Terminal Nut
   • 6 Nm
   • M6
3. Battery Positive Cable Terminal Clamp
   • Pay attention to the information regarding the threaded connection for the battery terminals.
4. Positive Cable Battery Terminal Nut
   • 6 Nm
   • M6
5. Battery
   • Vehicles with Start/Stop System: Follow the instructions for replacing the battery.
   • Disconnecting.
   • Connecting.
6. Clamping Plate
   • Note the assembly information
7. Clamping Plate Bolt

   • M8 x 35

Battery, Disconnecting

Note the following when charging or using the battery jump start terminal on vehicles with the Start/Stop System: first connect the charge cable to the positive terminal and then connect the body ground. This ensures that the battery sensor is not bridged. Charging the battery directly on the ground terminal will bridge the battery sensor and the battery data will not be recognized by the sensor during the charging process. The values stored in the data bus on board diagnostic interface regarding the battery condition no longer match the values for the charged battery.

WARNING

Risk of injury. Pay attention to all warnings and safety precautions.

Note

• By disconnecting the negative battery connection (opening the circuit), it is possible to safely work on the electrical system.
• The positive battery wire only has to be disconnected to remove the Battery.

• Switch off the ignition and all electrical consumers and remove the ignition key.
• Open the cover on the battery jacket -1-.

• Disconnect the battery ground cable terminal clamp -1- from the battery negative terminal.
• Disconnect the battery positive cable terminal clamp -2- from the battery positive terminal.

Connecting the Battery

Special tools and workshop equipment required

• Torque Wrench 1331 5-50Nm -VAG1331-

Note the following when charging or using the battery jump start terminal on vehicles with the Start/Stop System: first connect the charge cable to the positive terminal and then connect the body ground. This ensures that the battery sensor is not bridged. Charging the battery directly on the ground terminal will bridge the battery sensor and the battery data will not be recognized by the sensor during the charging process. The values stored in the data bus on board diagnostic interface regarding the battery condition no longer match the values for the charged battery.

WARNING

Risk of injury. Pay attention to all warnings and safety precautions.

Caution

Pay attention to the information regarding the threaded connection for the battery terminals.

Note

After connecting the battery and switching the ignition on, the ASR/ESP Indicator Lamp -K155- comes on and stays on. The indicator lamp goes out automatically when vehicle is driven a distance straight ahead at 15 to 20 km/h. This reactivates the Steering Angle Sensor -G85-.

Caution

Follow the procedure in the Repair Manual when disconnecting and connecting the battery.

Central battery venting hose must not be kinked, closed and/or damaged. Battery acids pose health risks and are explosive. Carefully route the hose making sure the battery is free and cannot emit any vapors into the passenger compartment.

• Attach the positive cable -2- to the battery positive terminal. Tighten the bolt to the tightening specification given in the assembly overview.
• Attach the battery ground cable terminal clamp -1- to the negative terminal. Tighten the bolt to the tightening specification given in the assembly overview.
• Perform the work steps listed in the table.
