2015 AUDI A3 engine oil

214 Checking and Filling
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 additives in the o il wi ll 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 .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports.
In order to provide effective lubrication and
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible
¢
page 215. Top off the oil at your earliest
convenience
~ page 215.
A WARNING
-~
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 210.
(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.

dealer has instructions about how to measure oil consumption accurately.
Checking the engine oil level

• Park your vehicle on a level surface.
• Let the engine run in id le briefly while it is at
operating temperature and then shut the
engine off.
• Wait approximately two minutes .
• Remove the oil dipst ick. W ipe off the oil dip·
stick with a clean cloth and inse rt it all the
way in again.
• Remove the dipstick again and then read the

D epending on the way the vehicle is driven
and the operating conditions, oil consumptio n
can be up to a 1/2 quart per 600 mi les
(0.5 liter per 1,000 km) . Consumption may be
h igher with in the first 3,000 miles (5,000
km) . Because of th is, the engine oil leve l must
be checked regularly . It would be best to
check each time you refue l your veh icle and
befo re long drives.

Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
ING S
r=>page 210.
The engine oil must be changed according to
the intervals specified in you r Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during norma l veh icle use.
Under some circumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe­ riods .
Detergent additives in the oil will make fresh
oil look dark after the eng ine has been run­
n ing 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 w ith the special tools and necessary ex­
pertise required, we strongly recommend that
you have you r o il changed by an author ized
A udi de ale r or a q ual ified servi ce station.
If yo u choo se to c hang e your o il yo urse lf,
please note the following important informa­
tion :
.8, WARNING
To reduce the ris k of persona l injury if yo u
m ust change the engine oil in your veh icle
yourself : -
Wear eye protection .
- To reduce the risk of burns from hot en -
gine oi l, let the engine cool down to the
touch.
- When removing the oil drain p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the tota l amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the reach of childre n.
- Continuous contact with used eng ine o il
is harmful to your sk in . Always protect
your skin by washing oil
off tho roughly
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 Aud i Limit­
ed New Veh icle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure
yo u know where you can properly dispose
of the used oil.
- Always dispose of used eng ine oil proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open st reams o r down
sewage drains.
- Recycle used engine oil by taking it to a
used eng ine oil collect io n fac ility in you r
are a, or contact a se rvice station.
coolant system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and genera lly re-
quires little attention. .,..

The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer's glycol-based coolant addi-
tive Gl3 antifreeze with anticorros ion addi ­
tives (50% fo r USA models; 60% for Canadian
models) . This mixture both assures th e neces­
sary frost protect ion a nd p rotects me tal com ­
ponents in the engine 's coo ling system from
corrosion and scaling.
It al so raises the boil­
ing po int o f the coo lant .
D o no t reduce the concentration of t he coo l­
an t in the summer by ad ding plain w ate r.
The
proportion of coolant additive must be at
lea st 50 % but not more than 60%
to main­
tain ant ifreeze protection and cooling efficien­
cy. If the coolant frost protect ion is too low ,
the coolant cou ld free ze and damage the veh i­
cle heating and eng ine cooling system.
F or yea r-round driv ing, antifreeze is added at
the facto ry for temperatures down to:
- -3 1 °F ( -3 5°C) USA
- -4 0°F ( -4 0°C) Canada.
If you must add coolant, use a m ixture of wa ­
ter and coolant addit ive. M ixing the coolant
addi tive wi th dist illed wate r is recom mend ed.

by an authorized A udi dealer or other quali­
f ied fac ility and the ca use corrected . If the
br ake fluid level is too low, the brake warning/
indica tor light w ill illuminate. Contact an au·
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moist ure from the air. If
the water content in the brake fluid is too
Che cking and Fillin g 219
high, co rrosion in the brake system may resu lt
after a period of time . The boiling point of the
brake f lu id will also decrease conside rably and
decrease braking performance.
T herefore, the brake fluid must be changed
eve ry two year s. Always use new brake f luid
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoi r can be difficu lt to
reach, therefore, we recomm end that you
have the brake fluid changed by your author­
i z ed
Audi dealer . Your dealer has the correct
tools, the right brake flu id and the know-how
to do this for you .
A WARNING
-
-Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal containe r
out of the rea ch of children!
- Brake failure can resu lt from o ld or inap­
p rop riate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SAE
spec ificat ion
J 1703 and conforms to
Federa l Motor Ve hicle Standard 116.
Always check with your authorized Audi
dealer to make sure yo u are using the
cor rect bra ke fluid. The cor rect type of
brake f luid is also i nd icated on t he
brake f lui d rese rvoir.
- The bra ke flu id must be new. Heavy us e
of the brake s can cause a vapo r lock if
the b ra ke fluid is left i n the system too

fall from a lift if there is a change in ve­
hicle weight distribution and balance.
This might happen, for example, when
heavy components such as the engine
block or transmission are removed .
- When removing heavy components like
these, anchor vehicle to hoist or add cor­
responding weights to maintain the cen­
ter of gravity. Otherwise, the vehicle
might tilt or slip off the hoist, causing
serious personal injury.
(D Note
- Be aware of the following points before
lifting the vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine
oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­
ance between the hoist and low parts
of the vehicle.
