Audi introduces a new model generation that is

obvious at first glance.

The front-end styling of both saloon and Avant

models is new, with the addition of the

characteristic Audi single-frame grille.

The rear end, with its distinct horizontal lines, and

the sides, where the shoulder line lends the body

a distinctly sporty look, are also new.

Driving pleasure, superior technology, exciting

styling and a level of luxury that even satisfies the

demands made of the luxury car class.

The architecture of the driver’s area, especially the

cockpit – a perfect synthesis of ergonomics,

function and design – is pioneering.

The body

Overview of the body

One of the key factors contributing to the vehicle's lower kerb weight was the use of high-strength body

panels, which account in total for 45% of the bodyshell weight. These special panels are used especially at the

body front end, where they are intended to absorb as effectively as possible the impact energy in the event of

a head-on collision.

In the floorpan area, the occupant cell is protected by three large tailored blanks in varying wall thickness. In

the occupant cell area, tailored blanks are connected sturdily and homogeneously to the front and rear ends

of the vehicle by a branched support system.

At the rear end of the vehicle, the side members are made from tailored blanks with different materials and

wall thickness.

Note

The repair concept is identical to that

of the Audi A4 ‘04 (B6).

Occupant protection

Safety system

The development objective for the safety system in the Audi A4 ‘05 was clearly defined: The system must

comply with all legislation now in effect and pass all current consumer tests, not to mention meeting Audi's

stringent in-house requirements.

The safety system in the Audi A4 ´05 is based on the systems in the Audi A3 Sportback and Audi A6 ‘05.

The complete system, as well as the adopted components, were adapted to suit the Audi A4 ’05.

safety system, refer to Self-Study

The safety system in the Audi A4 ´05 consists of the following components and functions:

–Airbagcontrolunit

–Driver and front passenger airbags, two-stage

–Frontsideairbags

–Sideguards(head airbags)

–Sideimpactdetection sensors on the C-pillar

–Sideimpactdetection sensors in the front doors (pressure sensors)

–Crashsensors for intelligent head-on collision detection, so-called upfront sensors

–Frontbelttensioners

Diagnosis

K-wire switch VAS 6017 B

Like in the Audi A4 ´01, K-wire switch is also required in the Audi A4 ´05 for communication between the

individual vehicle systems and the VAS testers.

Since the new control units are diagnosable via CAN only, the new K-wire switch VAS 6017 B must be used.

K-wire switch VAS 6017 B replaces switch VAS 6017 A.

Communication

If communication is to be established between a

control unit and a VAS tester, the tester sends the

appropriate address word via the diagnosis CAN

data bus.

The K-wire switch VAS 6017 B does not evaluate

signals on the diagnosis CAN data bus, rather it

relays them directly to the vehicle.

If the tester receives no response from the control

unit on the diagnosis CAN data bus, its resends the

appropriate address word, this time via the K-wire.

The K-wire switch receives this information and

relays it to the vehicle both on the K-wire and on the

L-wire.

If the control unit sends its response on the L-wire,

the K-wire switch detects this and establishes a

direct connection between the L-wire of the vehicle

and the K-wire of the tester.

As long as the tester is connected to a control unit

via the L-wire, the contact to the K-wire of the

vehicle is broken by the K-wire switch.
