Modifications to Audi A6 ‘05
The control unit with display in dash panel insert J285 is already known from the Audi A6 ’05. It was adapted
functionally to the new features of the Audi Q7.
Unlike the Audi A6 ’05, the Audi Q7 does not have an electro-mechanical parking brake; it is equipped with
a foot-operated mechanical handbrake. A switch, which is read by the control unit with display in dash panel
insert J285, is attached to the operating lever. When the switch is actuated, earth is connected and the
corresponding warning lamp is activated in the dash panel insert.
A new feature in the dash panel insert is the air spring suspension level indicator. This indicator is activated in
the centre display as soon as an automatic level change is performed. This is the case, for example, if the
system exits "lift" mode because a speed threshold has been exceeded; the suspension height will then be
lowered.
The level indicator can, however, be activated continuously by the driver by clicking the onboard computer to
the corresponding level with the Reset key.
A further new feature was implemented in the onboard computer. The driver has the option of displaying the
vehicle's current speed digitally. This is done by setting the onboard computer setting the onboard computer
to the corresponding level with the Reset key. On this level, the onboard computer variables can still be
retrieved in the case of a colour dash panel insert. The two diagrams show the vehicle speed display in
a colour dash panel insert and in a monochrome dash panel insert.
