WARNING: This page is about a different car, the 2017 Volkswagen Touareg and 2010 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools And Workshop Equipment Required

Battery Charger:VAS5900

NOTE:

If software updates or flash campaigns/actions must be performed on a vehicle, a charger with at least 70 A must be used in order to avoid problems during software updates and flash campaigns/actions.

Battery Charger:VAS5903 . Refer to BATTERY CHARGER .

Battery Charger:VAS5908 . Refer to BATTERY CHARGER .

WARNING:

Risk of injury. Follow all Warnings and Safety Precautions. Refer to WARNINGS AND SAFETY PRECAUTIONS .

WARNING:

Batteries that have a light yellow visual indicator do not have to be tested or charged. Do not give a jump start.

There is a risk of explosion during testing, charging or jump starting.

These batteries must be replaced.

NOTE:

The battery temperature must be at least 10 °C (50 °F).

-- Turn off the ignition and all electrical consumers.

-- Plug in the electrical system connector of the charger. The last selected battery type is shown on the display.

-- Select applicable battery type using INFO .

The symbol -1- for "standard charge of wet batteries" or the symbol -2- for "standard charge of Gel/AGM batteries" is indicated in the display.

-- Set the capacity (Ah) of the battery to be charged with the corresponding button "Up" ↑ or "Down" ↓ .

-- Clamp the red charging clamp "+" to the positive battery terminal.

NOTE:

In the case of vehicles with a start/stop function and an installed Battery Monitoring Control Module -J367-, the black charging clamp (-) must be connected to the body ground. The start/stop system will malfunction if it is connected to the negative terminal on the battery.

-- Connect the black charging clamp "-" to the negative battery terminal.

The battery charger recognizes the nominal voltage of the connected battery (6 V, 12 V or 24 V) and begins the charging process automatically.

At a charge condition of approximately 80 - 85%, charging unit begins the "Final-charging". The fourth bar is indicated on the display -1-. The battery is now ready to be used.

NOTE:

With the battery type "standard charge", parallel operation of consumers during the charging process is possible. The charging time is lengthened by this.

Depending on battery type, the charger switches over to sustain charging after approximately 1-7 hours. To achieve a 100% charge status, the battery should remain connected to the charger for that long.

Possible Malfunctions And How They Are Handled:

Displayed voltage does not match the nominal voltage:
-- Hold the appropriate button "Up" ↑ or "Down" ↓ until the charging process begins.
Displayed battery voltage does not match the nominal voltage - the charging process has already begun:
-- Press START / STOP twice.

-- Hold the appropriate button "Up" ↑ or "Down" ↓ until the charging process begins again.
The charger does not recognize a battery, when the battery voltage is less than 2 V:
The display remains unchanged.

The selected battery type and Ampere hours (Ah) are displayed.

End Battery Charging Process:

-- Press START / STOP .

-- Remove the black charging clamp "-" of the charger from the negative battery terminal.

-- Remove the red charging clamp "+" of the charger from the positive battery terminal.

-- Pull out the electrical system connector of the charger.
