Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise s teering with little effor t.
The advanced Servotronic® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortab le and safe steer ing response exactly matched to the
vehic le speed.
Power s teeri ng will not work if the engine is off . As a result, the
steering whee l wil l be hard to turn .
The power steering fluid level is checked during the scheduled
maintenance serv ices.
0 Note
If there is an electron ic ma lfunction, servotronic will sti ll funct ion
like a conventiona l power steering system, providing a constant
steer ing suppor t force that is no longer proportionate to the vehicle
speed . This is most noticeable when turning the steering wheel at
low speeds (for examp le w hen parking), -more effor t wi ll be
required than usual.
• Be aware of the different than usua l steering response and
adjust your steering force accordingly .
• Have the problem checked and set right by an Aud i dea ler as
soon as possib le.

[
i ] Tip s
• When the engine is running, never hold the steer ing whee l
turned all the way to the right or to the left for longer than 15
seconds. The power steer ing pu mp wil l overheat the hydraul ic fluid
if you keep ho lding the steering whee l turned a ll the way. This is
like ly to damage the power steering system.
• I f the power steering system shou ld fail entire ly, or if the engine
is not runn ing ( for examp le, wh ile be ing towed), you w ill st ill be able
to steer the vehicle . However, considerably more effort will be
requ ired to do so.
• I f the power steering system shou ld have a leak, or is not func
tioning properly, contact your author ized Audi dealer im mediately.
• The power stee ring system requires a special ly formulated
hydrau lic fluid . The power steer ing reservo ir is the one located most
forward on the left side of the engine
compartment => page 308. The
correct flu id level in the reservo ir is important for proper func
tioning of the power steering. •
Driving with your quattro®
With All Wheel Drive, all four wheels are driven.
Genera l inf orm ati on
With All Whee l Drive, power is d istributed to all fo ur wheels. This
happens automatically depending on your driving style and the
road condi tions at the time . See
a lso => page 269, "Electronic differ
entia l lock ! EDU" .
Winter tires
When driving in the winter, your vehicle with All Wheel Drive has an
advantage, even with regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-season tires) for improved
driveabi lity and braking: these ti res must be mounted on all four
wheel s. See
also=> page 341, "Winter tires". ~

Engine oil consumption
The engin e in your vehicle d ep ends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effect ive lubrication and cool ing of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumption varies from engine to eng ine
and may change significantly over the life of the engine . Typically,
eng ines wi th a specif ied break -in period
(see => page 2771 consume
more oil during the break -in period than they consume after oi l
consumption has stabi lized .
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
co ndensation or fue l residue and the oxidation level of the o il. As
any engine is subject to wear as mileage builds up, the oil consump
t io n may increase over time until rep lacement of worn components
may become necessary .
With all these variables coming into play, no standard rate of oil consu mption can be estab lished or specified. T here is no a lternative
to regular and frequent checking of the oil level, see
Note .
If the yellow eng ine o il level warni ng symbol in the instrume nt
cluster ~ lights up, you should check the oil level as soon as
poss ible
with the oil dipstick => page 311 . Top off the oil at your
earliest
convenience=> page 312.

Bef ore you che ck anything in the eng ine comp artment , alw ay s

Driving with an insuff ic ie n t o il level is l ikely to cause severe damage

going on a long trip.
• I f you have the impression your engine consumes excessive
amounts of oi l, we reco mmend that you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
t hat t he acc urate measureme nt of oil consump tion requ ires g reat

about how t o measure oil consumpt ion accurately. •

Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fue l injection and
emission contro l systems, and the genera lly increasing techn ica l
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carr ied out by veh ic le
owners.
Also , safet y and env ironmental concerns p lace very strict
l im its on the nature of repairs a nd adjustmen ts t o engine and trans
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment availab le to spec ia lly trained
workshop personne l in order to assure proper performance, reli
abil ity and sa fety of the vehicle a nd its many systems.
I mproper maintenance, adjustments and repairs can impair the
operat ion a nd rel iabil ity of your vehicle and even vo id your vehicle
warranty. Therefore , proof of servicing in accordance with the main
t enance sched ule may be a cond ition fo r uphold ing a p ossi ble
warranty claim made within the warranty period.
