The New Audi A6 Avant ´05
Self-Study Programme 344
Vorsprung durch Technik www.audi.de Service Training
Audi is adding a new chapter to the success story of
the Avant.
The new Audi A6 Avant '05 represents a unique
blend of design and dynamism, driving pleasure
and functionality.
Here is a car that exhibits a unity and harmony of
design.
Measuring 4.93 metres in length, 1.86 metres in
width, and 1.46 metres in height, the new
Audi A6 Avant ´05 visibly sets a new standard in
terms of its proportions.
The lines of the car combine the clear architecture
typical of Audi with other core elements of the
brand's progressive design.
The already classic proportions of the Avant's
silhouette, with its high shoulder line, narrow
windows all round, coupé-like roofline and shallow
sloping tail end, have been infused with added
dynamism.

Introduction

Tailgat e
In the new Audi A6 Avant ´05, an inner tailgate hinge
is implemented for the first time.
The hinge is attached to the upper roof crossrail at
the rear so that it is located behind the tailgate seal,
and thus inside the occupant cell.
When the tailgate is closed, the hinge is concealed
behind the trim panel and is not visible from the
interior.
This hinge arrangement and function has the
following advantages:
–nocorrosion,
–nosealingproblems,
–internal wiring,
–nogrommets are needed to seal through-holes
in the body,
–largercargo area
possibility for electric tailgate drive.

Occupant protection
Reference
For further information on the safety
system, please refer to Self-Study
Programme 323 - Audi A6 ´05.
Front passenger front airbag
–Airbagigniter 1, front passenger side N131
–Airbagigniter 2, front passenger side N132
The front passenger airbag consists of a casing in which are housed two pyrotechnic gas generators
separated by a partition. A propellant in the form of tablets and hollow tabs is used.
Safety system
The goal was to implement a protection system that offers a very high level of safety, thereby raising still
further the high safety standard set by the current Audi fleet.
The many safety requirements for the new Audi A6 Avant ´05 included meeting all current legislation, as well
as achieving a top rating in consumer tests.
Audi's internal specifications often increase the challenges to the development team.
This was the case with the Audi A6 saloon introduced to the market in the 2005 model year; likewise with the
new Audi A6 Avant ´05.
The occupant protection system in the Audi A6 Avant ´05 was largely adopted from the saloon. Due to the
modifications to the body, however, several components were adapted to the new parameters.
A new gas generator with dual threshold deployment for the front passenger front airbag will be implemented
in the Audi A6 saloon in early 2005. This module will be fitted to all models world-wide.
The new Audi A6 Avant ´05 will be equipped with this airbag from rollout.

Airbag igniter 2, front passenger side N132
The airbag control unit defines the time interval between the deployment of airbag igniter 1, front passenger
side N131 and airbag igniter 2, front passenger side N132 according to the type and severity of the accident.
The task of the second gas generator is to inflate the airbag to its full size.
The second gas generator has exactly the same function as the first gas generator.
Airbag igniter 1, front passenger side N131
If igniter I is electrically activated by the airbag control unit J234, it ignites priming charge I. Under the
resulting pressure, the flame passes through the rupture disc and ignites propellant charge I.
On account of the hollow propellant tabs, the complete propellant charge ignites more quickly.
The metal filter cools and treats the developing gas before it flows through the outlets to the airbag.
The task of the first gas generator is to inflate the airbag.

The 3.0l V6 TDI was modified in several respects to
fill the gap between the 2.5l V6 TDI with distributor
injection pump and the 3.0l V6 TDI with common rail
injection. A wide range of diesel engines in various
sizes is therefore available to the customer.

–Thestrokewas reduced from 91.4 mm to
83.1 mm by modifying the crankshaft, con-rod
and piston
–Castexhaust manifold and steel compensator
without air-gap insulation
–Deletion of the shield plates above the manifolds
–Piezoinjectors with eight-port nozzles instead of
seven-port nozzles
–Aninletrestrictor has been integrated into the
fuel rail for each injector
Engine
Modifications to the 2.7l engine
The basis is the 3.0l V6 TDI CR engine, i.e. the engine
block with 90 mm cylinder spacing was adopted,
likewise the 83.0 mm cylinder bore.
The crankshaft, the con-rod and the pistons were
modified so that a swept volume of 2698 cm3was
obtained by changing the stroke.
