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 lubr ication and cool­
ing of internal engine components, a ll inter nal
202
combust ion engines consume a certa in amo unt
of oil. Oil consumption varies from engine to en­
gine and may change signi ficantly over the life of
the engine. Typically, engines w ith a specified
break-in period (see
c:::;, page 66) consume more
o il dur ing the break-in per iod than they consume
af ter o il consumption has stab ilized .
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revo lutions per m inute) at
wh ich the engine is operated, the amb ient tem­
perature and road condit ions. Furt her facto rs a re
the amo unt of o il di lution from wate r condensa ­
t ion or fue l resid ue an d the oxidation level of the
o il. As any engine is sub je ct to wear as mileage
builds up, the oi l cons umption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumption can be estab ­
li shed or spec ified. The re is no alte rnative to reg­
ul ar and freq uent checking of the oi l level, see
Note .
If the yellow engine oi l level warning symbo l in
the instr ument cluster
El lights up, yo u should
check the o il level as soon as possible
c:::;, page 203. Top off the o il at your ea rliest con­
venience

A WARNING
Before you check a nyth ing in the e ng ine com­
par tment, always read and heed all WARN­
IN GS
c:::;, .&. in Working in the engin e compart­
ment on page 198.
(D Note
Drivi ng w it h an insuff ic ient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warn ing d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and alway s before going
on a long trip .

Obse rve the safety precautions¢ &. in Working
in the engine compartment on page 198 .
Checking the engine oil level
.,. Park the vehicle on a level surface.
.,. Shut the engine off when it is warm. Wait ap­
prox imately two m inutes so that the engine oil
can flow back in to the oil pan .
.,. Switch only the ignition back on.
.,. Se lect: the

Check ing and Filling
.,. Close the engine oi l filler open ing cap "t!:r. .
.,. Close the hood, restart the ignition after two
m inutes and read the current o il leve l in the In­
fotainment system.
A WARNING
-When adding oil, do not let oi l dr ip onto hot
e ngine components. This increases the risk
of afire.
- You must seal the cap on the oil filler open­
ing correctly so that oi l does not leak ou t
onto the hot engine and exhaust system
when the engine is runn ing, be ca use this is
a fire hazard.
- Always clean sk in thoro ughly if it comes into
con ta ct w ith eng ine oi l.
d) Note
-The e ngine o il level must not be under the
"min" marking, beca use this increases the
r is k of engine damage.
- If the message
Oil level is too full. Pleas e
reduce
oil level. appea rs, the re is too m uch
oil in the engine and the re is a r is k of cata­
lyt ic converte r and engine damage. Do no t
start the eng ine. Co ntact an a uthorized Audi
dea ler or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry.
-Do not mix any ad ditiona l lubricants into
the engine oil. Damage caused by such add i­
tives is not covered by the warranty .
@ For the sake of the environment
- Oil sho uld never enter the sewer system or
come into contact with the ground .
- Pay attention to lega l req uiremen ts when
disposing of empty oil containers .
(D Tips
- T he oil level in dicator in the inst rumen t
cl uster display is only an informationa l dis ­
play. If the o il level is too low, a minim um
oil warn ing appears in the instrument clus­
ter. Add oil and close the hood. The c urrent
oil level is d isplayed in the Infotainment

Checking and Filling
system the next time the ignition is
switched on.
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1 ,000 km),
depending on driving style and operating
conditions . Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
cause of this, the engine oil level must be
checked regularly .
It would be best to check
each time you refuel your vehicle and before
long drives .
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compart ­
ment ,
always read and heed all WARNINGS q .&.
in Working in the engine compartment on
page 198.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances , operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
chang e the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, 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 information:

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 engine
-
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 running 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 engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly .
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed. ..,.

Checking and Filling
_& WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning .
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance .
