Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can r un
smooth ly and reliably. Choosing the right o il
and changing oil within the t ime and mileage
intervals p rin ted in you r vehicle's Wa rranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has deve loped
a specia l quality sta ndard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera­
tion.

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hanging the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor .
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent addit ives in the oil will make fresh
oil look dark after the eng ine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine). Your
Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to fol­
low recommended maintenance and use re­
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover­
age unless you present to the dealer proof in
Checking and filling 231
the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see ¢
page 204) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption 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 fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary .
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­
el, see
Note .
If the yellow engine oil level warning symbol
in the instrument cluster
II! lights up, you
should check the oil level as soon as possible
¢
page 232. Top off the oil at your earliest
convenience

-The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running - fire hazard!
-If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
@ Note
-Check the oil level using the MMI. If the
message
Please reduce oil level appears,
contact your authorized Audi dealer or
other qualified workshop to have excess
oil extracted if necessary .
-Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station .

T he engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet . This is very important
because the lubricating properties of oil di­
minish gradually during normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions , or have your vehicle where tempera-

tu res remain below freezing for extended pe­
riods.
Detergent additives in the oil will make fresh
oil look dark after the engine has been run­ ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex­
pertise requir ed, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choose to change your oil yourself,
please note the following important informa­
tion:
_& WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to hold at least the total amount of oil in
your engine .
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil
off thoroughly
with soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Vehicle Warranty.

6. If your vehicle will be towing
a trailer, load from your trail­
er will be transfe rred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle.
... check the tire sidewall
(q page 254, fig. 204) to de­
termine the de signated load
rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

the tire sidewall (for examp le "TWI" or other
symbols) indicate the positions of the tread
wear indicato rs . Worn tires must be rep laced .
D iffere nt figures may apply in othe r countr ies

Tire pressure
Incorrect t ire pressure causes premature wear
and can cause sudden tire blow-out. For this reason, tire pressure must be checked at least
once a month ¢
page 249.
Driving style
Driving fast around curves, heavy acce lerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires a re rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­ ing:
- Tire rotation intervals may differ from the
veh icle service interva ls outlined in your
Warra nty
& Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend t hat you
follow t he tire manufacturer's suggested
tire rotation intervals.
- Veh icles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pared to all-wheel drive (quattro).
- Please rotate tires as shown ¢
fig. 203.
- Extra care must be taken when rotating di-
rection-specific tires¢
page 2 71 .
Wheel balancing
The wheels on new veh icles are balanced.
However, various situations during everyday
driv ing can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steer ing wheel. ..,.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This appl ies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb ho lders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bu lbs and the expertise .
Gas discharge lamps (Xenon lights):
Fuses and bulbs
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Head lights w ith Xenon light can be identified
by the high voltage sticker.
LED headlights* require no maintenance.
Please contact your authorized Audi dealer if a
bulb needs to be replaced.
_& WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death .
- Xenon bulbs are pressur ized and can ex­
plode when being changed .
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
&_ WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Serious personal injury may result
from improperly performed work.
(D Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
¢page 227¢ &.
- It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .

28 6 Con sum er Inf ormation
comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afety an d e nvir onm ent al con­
cerns place very strict limits on the nature of repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure proper
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­ ranty. Therefo re , proof of servici ng in accord­
ance w it h the ma intenance sched ule may be a
condition for upholding a possible warranty
claim made within the warran ty period.
Above all, operational safety can be adve rsely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any serv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop .
We strong ly urge you to give your authorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and tra ined spec ialists to keep your vehicle
running properly .
Performing lim it e d m aint en anc e y ourself
The fo llowing pages describe a limited num­
ber of procedures which can be performed on
you r vehicle with ordinary too ls, shou ld the
need arise and trained personnel be unavaila­
ble. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and ca refully follow the instruc­
tions given. Always rigorously obse rve the
WARNINGS p rovided .
Before you ch eck anything in th e engin e
compartme nt, alway s read an d heed all WARNINGS

22 7 .
A WARNING
--Serious personal in jury may occur as a re-
sult of improperly performed mainte­ nance, adjustments or repa irs.
- Always be extremely careful when work­
ing on the vehicle. Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r isk personal
in jur y.
- Do not attempt any of the maintenance,
checks or repairs descr ibed o n the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re­ spect to the ve hicl e, or are uncerta in how
to proceed .
- Do not do any work withou t the proper
too ls and equipment . Have the necessary
work done by your authorized A udi deal ­
er or anothe r properly equipped and
qualified workshop.
- The engine compar tment o f any motor
vehicle is a potentially hazardous area. Never reach into the area around or
touch the rad iator fan. It is temperature
control led and can sw itch on suddenly -
even when the engine is off . The radiator
fan switches on automatically when the
coo lant reaches a ce rtain temperature
and will cont inue to ru n until the coo lant
tempera ture drops.
- Always sw itch off the ignition before any­
one gets under the vehicle.
- Always support your veh icle with safety
s tands if it is necessary to work under­
neath the vehicle. The j ack s upp lied with
the vehicle is not adequate for this pur­
pose and cou ld co llapse causing serio us
pe rsonal injury .
- If you must work underneath the vehicle
wit h the wheels on the ground, a lways
make sure the vehicle is on leve l ground,
that the wheels are a lways secure ly
blocked and that t he engine cannot be
started .
