6.1 Electric drive motor - V141-
6.1.1 General description
The electric drive motor - V141- -1- is located between the com‐
bustion engine and the gearbox.
It acts directly on the gearbox input shaft and has the following
functions:
♦ A drive motor to propel the vehicle with electric power only
♦ A generator to supply the electrical system with power and
charge the hybrid battery unit - AX1- .
♦ A starter to start the combustion engine.

motor - V141-
WARNING
Working on vehicles with high-voltage wiring:
• Do not support yourself or tools on high-voltage wiring or
associated components --> this can damage the insula‐
tion.
• High-voltage wiring must not be excessively bent or
kinked --> this can damage the insulation.
• The round high-voltage connectors are colour-coded with
an external coloured ring and are provided with mechan‐
ical coding or guide lugs. It is important to observe this
coding when joining up the round high-voltage connec‐
tors, otherwise the connectors can be damaged.
Removing
The electric drive motor - V141- is a component of the gearbox,
so the gearbox first has to be removed.
– De-energise high-voltage system.
The high-voltage system must be de-energised according to the
"Guided Fault Finding" routine in the ⇒ Vehicle diagnostic tester,
and ONLY by this method.
