❑ Nuts for securing battery tray to body: 15 Nm

1.2 Removing and installing battery
Special tools and workshop equipment required
♦ Torque wrench - V.A.G 1331-
WARNING
Risk of injury. Comply with the warning notices and safety reg‐
ulations ⇒ page 1 .
Caution
To disconnect and reconnect the battery, the procedure de‐
scribed in the workshop manual should be strictly adhered to
⇒ page 5 .
Replacing battery on vehicles with start/stop system:
Because of its higher deep-cycle resistance, only a special starter
battery is used in vehicles with a start/stop system.
When renewing the starter battery, note correct part designation
in ⇒ ETKA (electronic parts catalogue) . Starter batteries for use
in vehicles with a start/stop system are marked with “AGM” (Ab‐
sorbent Glass Mat) or “EFB” (Enhanced Flooded Battery).
Note
♦ In vehicles with a battery sensor (start-stop system), the bat‐
tery has to be parameterised after a new starter battery has
been installed.
♦ The battery parameterisation sends the technical data of the
new battery to the battery monitor.

– Undo and remove bolt -1- and remove clamping plate -2-.
– Remove battery -4-.
Installing
Caution
A loosely fitted battery creates the following dangers:
♦ Shortened service life caused by vibration damage (dan‐
ger of explosion).
♦ Damage to the grid plates of the battery.
♦ Damage to battery casing by clamping bracket (possible
leakage of acid with high consequential costs).
♦ Poor crash safety.
Install in the reverse order of removal, observing the following:
– Place battery -4- on battery tray -3- and push towards rear.
– Put clamping plate -2- on and secure with bolt -1-.
– Check battery is firmly seated after installation.
– Connect battery ⇒ page 5 .
Note
♦ In vehicles with a battery sensor (start-stop system), the bat‐
tery has to be parameterised after a new starter battery has
been installed.
♦ The battery parameterisation sends the technical data of the
new battery to the battery monitor.
♦ Performing battery parameterisation ⇒ page 5 .

tem:
When recharging or jump starting vehicles with start/stop system,
note the following: first connect charging cable to battery positive
terminal then body earth. This ensures that the battery sensor is
not bridged. The direct charging of the battery on the negative
terminal clamp means that the battery sensor is shunted and the

nostic interface do not then correspond to the values of the
charged battery.
WARNING
Risk of injury. Comply with the warning notices and safety reg‐
ulations ⇒ page 1 .
Disconnecting battery
Note
♦ By disconnecting the battery earth wire (open circuit), safety
is ensured when carrying out work on the electrical system.
♦ The battery positive wire need only be disconnected for re‐
moval of the battery.
– Switch off ignition and all electrical consumers, and withdraw
ignition key.
– Fold up cover (if fitted) of earth wire on battery terminal clamp.
– First, undo the nut of earth wire battery terminal clamp -1- and
pull terminal clamp off battery negative terminal.
– Fold up cover of electronics box -1- and remove nut -2-.
– Release the catches -arrows- on each side of the electronics
box holder and remove electronics Box together with holder
upwards off the battery.
