Networking system
The networking system in the Polo is based on the new MQB-A0 platform and comes in two variants:
•
•
Standard
Standard Plus
The two variants differ in the fitting locations of the data bus diagnostic interface J533 (gateway).
Standard
The gateway is integrated into the onboard supply
control unit J519 (BCM) in the Standard system.
The Standard system is installed in Polo models with
manual gearboxes. The BCM with integrated
gateway is located directly on the relay and fuse
holder SC in the interior.

Standard Plus
Data bus diagnostic
interface J533
The Standard Plus system has an external gateway. This
is located opposite the onboard supply control unit on
the fuse holder SC. The Standard Plus system is used for
dual clutch gearboxes in conjunction with the
mechatronic unit for dual clutch gearbox J743. In order
to use the bus load in the powertrain CAN bus in an
optimum way, individual control units, for example, the
Power steering control unit J500, have been moved to
the running gear CAN bus.
