2015 AUDI TT ROADSTER check oil

oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­based engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
" sludge," that over time can lead to expensive
repairs .
At the time of printing, engine oils available in the U .S . and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean,
however, that every synthetic engine oil will
meet Audi oil standard VW 502 00 . So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posits use only oil with the following specifi­
cations printed on the oil container :
Audi oil standard VW S02 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards .
Viscosity
Engine oils are graded according to their vis­
cosity . The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem­
perature ranges for normal driving conditions.
However, if engine oil viscosity grade SAE
SW40 is not available, you can also use viscos­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil quali ty standard VW 502 00
specifications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that expressly conforms to the
Checking and filling 167
VW 502 00 specification, in case you have to
top
off the oil while on the road.
Only if the level of the oil is at or below the
minimum mark on the oil dipstick - and no oil
that expressly conforms to Audi oil standard
VW 502 00 specifications is available - may
you top
off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only
in viscosity grades SA E SW-40, SA E 5W -30, or
SAE OW-40. However, during the entire time
between oil change intervals, never top
off
with more than a total of 0.5 qt/liter engine
oil that does not conform to Audi oil specifica­
tion VW 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your autho rized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa .com or
www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) 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 Serv ice Adv isor.
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.

168 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led 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 ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::> page 149) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
1\1 lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::> page 169. Top off the
o il at your earliest conven ience
c::> page 169 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS

comportment on page 164.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil level in
your engine at r egular intervals, pr ef­
erably ea ch time you refuel, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requires great care and may
take some t ime . Your Audi dea ler has in­
st ruct ions about how to measure oil con­
sumption acc urately.

170 Checking and filling
-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 .
(D Note
-The oil level must not be above range G)
-danger of converter or engine damage!
Contact an authorized Audi dealer to
draw off oil, 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 .
Before you check any thing in the engine com­
partment,
always read and heed all WARN­
INGS ~ .& in Working in the engine compart­
ment on page 164 .
The engine oil mus t 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 required, 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:
A 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.

@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling 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 sea led and generally re­
q uir es lit tle atten tion .
The cooling system has been filled at the fac ­
tory with a pe rmanent coo lant which does not
need to be c hanged. The coolant consists of a
mixture o f spec ial ly conditioned water and the
manuf acturer 's glyco l-basedcoolan t addi -
tiv e G13 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els) . This mixture both assures the neces­
sary
frost protection and p rotects metal com ­
ponents in the engine's coo ling system from
corrosion and scaling . It a lso raises the boil­
i ng point of the coolant .
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add it ive must be at
l e a st 50 % but not mor e than 60 %
to main­
tain antifreeze protection and coo ling efficien­
cy .
If the coolant frost protect io n is too low,
the coolant cou ld free ze and dam age the veh i­
cle heating and eng ine cooling system.
For yea r-round driving, antifreeze is added at
the fac to ry for tempera tures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.
Checkin g and fillin g 171
If you must add coo lant, use a mixture of wa ­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended.
_& WARNING
Before you c heck anything in the engine
compartment, always read and heed a ll
WARNINGS
c> .& in Working in the engine
comportment on page 164.
Q) Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate condi tions. This is especi ally impor­
tan t if you live i n a region wher e th e win­
ter is ex treme ly co ld . If necessary, i n­
crease t he p ropo rtion of coo lant add itive
to 60% .
- Whe n ad ding coolant additive t o yo ur

Brake fluid
Checking brake fluid level
Fig . 133 Engine compa rtment: cove r on the brake fluid
reservo ir
Before you check anything in the engine com­
partment,
a lw ays read and h eed all WA RN­
ING S ¢&. in Working in the engine compart ­
ment on page 164.
,.. Read the brake fluid level from the brake
fluid reservoir¢
page 166, fig . 128. T he
brake flu id leve l must be between the "MIN"
and "MAX" markings.
The brake flu id rese rvo ir is located behind the
rear part ition of the eng ine compartment o n
the left side ¢
page 166.
The fluid level may drop slightly after some
time due to the automatic adjustment of the b rake pads . This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U.S. models: . , Canadian mod­
e ls: . ) w ill come on
¢page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warn ing/
indicator light w ill illuminate. Contact an au­
thor ized Audi dealer
imm ediatel y.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
eve ry two y ears. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer . Your dealer has the correct
tools, the right brake fl uid and the know -how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also ind icated on the
brake flu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
