Mechanical speedometer without speed sensor in the speedometer cable
A speed sensor must be built into the speedometer cable to generate a
digital signal.
The VDO Adapter 2152.30300000 or a vehicle-specific adapter that
fulfils the minimum requirements can be used. The VDO speed sensor
is suitable for direct installation on the gearbox (no further installation
parts required) or in the speedometer cable (in conjunction with
additional universal installation parts).

display cannot be guaranteed. Incorrect installation leads to
improper functioning of the navigation system or of the
speedometer.
