Bi-xenon headlights
Bi-xenon headlights are installed with the
"XenonPlus" option.
The following lamps are fitted in the bi-xenon
headlight:
– A blue W5W lamp for the parking light.
The colour of the parking light thus corresponds
to the xenon light.
– A D2S lamp for high beam headlight, headlight
flasher and dipped beam headlight. The covers
fo r d i p p ed b e am a re al s o a c t i v at e d fo r h i gh b ea m
and headlight flasher operation.
– A P21W lamp for the daytime driving light.
This comes on dimmed to 90 %.
– A PY21W bulb coated with a reflecting layer of
silver is used as the direction indicator light.
Only longlife lamps are used. A super-longlife
lamp is used as the daytime driving light.
The following country-specific variants exist:
– No daytime driving lamp is fitted for Japan.
– 3457NA flasher lamps are used for USA and
Canada.
The headlights are changed over to left-hand drive
via a lever on the projection module.
A dynamic headlight range control system is
installed for bi-xenon headlights.
The dynamic headlight range control system uses
the well-known level sensors. This send the
information about the vehicle level to the control
unit for headlight range control J431 via a pulse
width-modulated signal.
The same level sensor is fitted on both the front and
rear axle.
Headlights are also available with dynamic
corner-sensitive lights.

You may already be familiar with the acoustic
parking aid function "APS" from the Audi A3 ´04.
For use in the Audi A6 ´05, a 4-channel system with
sensors on the rear bumper and an 8-channel
system with sensors on the front and rear bumpers
are available.
Ve rs i on s
The parking aid control unit will be available as
4-channel system and 8-channel system versions.
Only the 4-channel version is available on the
Audi A6 ’05 for the US market.
Installation position
The parking aid control unit is installed above the
right wheel housing in the boot. It is secured in a
frame under the control unit for trailer detection.
Function
The area around the vehicle is monitored by four
ultrasound converters integrated into the front
bumper (8-channel system only) and four
ultrasound converters integrated into the rear
bumper. The acoustic message comes from a tone
generator in the front area of the vehicle and a tone
generator in the back area of the vehicle (only at the
back for the 4-channel system). A parking aid switch
can be used to activate or deactivate the parking aid
manually (8-channel system only). The MMI allows
the customer to adjust the volume and frequency of
the acoustic output of the parking aid.
If the control unit for trailer detection reports the
presence of a trailer on the vehicle via the CAN bus,
the four sensors in the rear bumper are switched
off. The front area of the vehicle is still monitored,
however.
