Volkswagen Workshop Service and Repair Manuals

Note:

When the battery is reconnected, check the vehicle equipment (radio, clock, electrical windows) as per Workshop Manual and/or the owner's manual.

→ Removing battery:

• ‒ First disconnect battery earth strap on battery negative pole
• ‒ Then disconnect the battery positive wire on battery positive terminal.

• ‒ → Remove battery clamping bracket
• ‒ Remove hexagon bolt M8 x 25

→ Installing battery:

Note:

The latest generation of batteries are equipped with a central gas venting system and a fine mesh flame trap.

Function: The gases produced during charging escape through a central opening on side of upper cover. A flame trap is integrated into this position which prevents the flammable gases in the battery from igniting.

It is extremely important to check that the hose is connected to the central gas venting system and that it has not been disconnected whilst installing. Only then can the battery vent via the fine mesh flame trap and hose.

The flame trap is comprised of a small round fibre glass mat with a diameter of 15 mm and a thickness of 2 mm. It works on a similar principle to a valve therefore it allows the gases produced in the battery to vent.

•      1 -     Retaining strip for battery lower flange
•      2 -     Clamping bracket must press onto battery lower flange
  It is important that only batteries with a 10.5 mm lower flange are installed.
•      3 -     Hexagon bolt M8 x 25 (tightening torque 22 Nm)
•      4 -     Battery securing pedestal

Note:

When the battery is reconnected, check the vehicle equipment (radio, clock, electrical windows) as per Workshop Manual and/or the owner's manual.

Checking battery is seated securely.

There is a danger of the following if the battery is not properly secured:

• ‒ Shortened service life caused by vibration damage
• ‒ The cells in the battery will be damaged if the battery is not secured correctly.
• ‒ Damage to battery housing by clamping bracket (possibility of acid leaking, therefore subsequent higher costs).
• ‒ Poor crash safety
