2021 AUDI Q2 engine oil

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

Closing the tank cap

•
Screw on the tank cap clockwise until
it
clicks
audibly.

•
Close the tank flap. Make sure you hear
it
click
into place.
When the automatic filler nozzle is operated cor­
rectly
it
will switch itself off
as
soon as the tank
is
fulL.
Do not try to put in more fuel after the
nozzle cuts out, as this will fill the expansion
chamber in the fuel tank.
The correct fuel grade for your vehicle is given on
a sticker on the inside of the tank flap. Further

A WARNING
Fuel is highly inflammable and can cause
seri­

ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis­
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.

A WARNING
- Ensure that no engine oil comes into contact
with hot engine components when topping

up:
this could cause a fire.
- The oil filler cap must be properly closed to
prevent oil from squirting onto the hot en­
gine or exhaust system while the engine is
running - risk of fire!
- Wash your skin thoroughly if it comes into
contact with engine oil.
- The engine oil must never drop below the
marking®
^>Fig.
246- risk of engine dam­

age!

- When topping up the engine oil, make sure
that the oil level is not above the marking

@
^Fig.
246, as this may result in damage
to the catalytic converter or to the engine.
Do NOT start the engine. Contact a qualified
workshop to extract the engine oil if neces­
sary.
- Applies to vehicles which have an oil
dip­

stick with area

Fig. 246: If you run your
vehicle on diesel fuel of poorer quality than
EN 590 standard
fuel,
the fuel can get into
the engine oil. In this case, the oil level
gradually rises and the quality of the engine
oil decreases. Once the oil level has reached
the marking
@
or the indicator lamp
E

has come on, the engine oil level must not
be corrected by extracting the surplus oil -

risk
of engine damage! The engine oil must
be changed
^>page
34.
- No additives should be used with engine oil.
Any damage caused by the use of such
addi­

tives would not be covered by the factory
warranty.
© For the sake of the environmen
- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
© Note
Depending on
how
you drive and the condi­
tions in which the car is used, oil consumption
can be up to 0.5
Itr./lOOO
km. Oil consump­
tion is likely to be higher for the first 5,000

km.
The engine oil Level must be checked at
regular intervals, preferably when refuelling
and before setting off on a long trip.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
|
<^page
30. However, we recommend that it
should be checked occasionally.
If you do need to top up the coolant, use a mix­
ture of water and coolant additive. We recom­
mend mixing coolant additive with distilled wa­
ter.
299

Checking and topping up fluids
Coolant additive
The coolant additive contains anti-freeze and cor­
rosion protection agent. Only use one of the
fol­

lowing coolant additives. It is possible to mix
these additives.

The amount of coolant additive which needs to
be mixed with the water depends on the temper­
atures to be expected in the winter season. If the
anti-freeze concentration is too Low, the coolant
can freeze and cause engine damage.

CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra­
tion is adequate for the conditions to be ex­

pected.
This applies particularly if
you
drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa­

ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

Checking coolant level

•
Park the vehicle on a level surface.

•
Switch off the ignition.

•
Read off the coolant level on the coolant ex­
pansion tank
^>Fig.
248. When the engine is

cold,
the coolant level should be between the
marks. When the engine is warm, it may be
slightly above the top mark.
Topping up coolant
Important: The coolant expansion tank must not
be empty
•=>([).

•
Wait for the engine to cool down.

•
Cover the cap on the expansion tank with a

cloth,
and carefully unscrew the cap
anti-clock­

wise
<=>
/K.

*-
Add coolant in the correct concentration

tapage
299 up to the top mark.

•
You should make sure that the fluid level re­
mains stable. If necessary, add more coolant.

•
Screw the cap on again tightly.
Any loss of coolant normally indicates a Leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system

checked.
If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.

Checking and topping up fluids
© CAUTIO
-The anti-freeze concentration must be
matched to the climate of the country in
which you are driving. If the concentration
is too
high,
damage to the car may result.
- Never put in radiator anti-freeze or other
additives.
- Never use washer fluid which contains paint
thinners or solvents as it can damage the
paintwork.
Service interval display

The
service interval display detects when the
next
service
is due
for
your vehicle.
There are two service interval dispLay levels:
- Inspection or oil change reminder: After a cer­
tain mileage, a service reminder will appear in
the instrument cluster dispLay each time the ig­
nition is switched on/off. The distance or time
remaining will be shown briefly.
- Inspection or oil change due: When your
vehi­

cle is due for an inspection, oil change or
both,

the corresponding reminder Inspection
due!,

Oil change due! or Oil change and inspection

due!
will appear briefly after you switch the ig­
nition on/off.
Checking the service intervals
On the infotainment system, you can look up the
distance and time remaining until the next oil
change or next service inspection. Select the
fol­

lowing on the infotainment system:
|MENU|
but­
ton > Car
>
left control button > Servicing &
checks
>
Service intervals.

Applies
to: vehicles with flexible oil change service
You cannot check the service interval on a new
vehicle until it has been driven for about 500 km.
Qualified workshops reset the service interval af­
ter the oil is changed. The distance to the next oil
change is initially displayed based on the driving
profile prior to the oil change. Your own personal
driving profile is used subsequently to calculate
the remaining distance. Frequent cold starts or
short trips place extra demands on the engine oil
with the result that the oil has to be changed
more often.
Resetting the display
Your qualified workshop resets the service inter­
val display after each service.
It is very important that you reset the oil change
dispLay if
you
change the oil yourself. The
next
oil
change will be due after
a
fixed service interval.
To reset the display, select the following on the
infotainment system:
|MENU|
button > Car
>
left
control button > Servicing & checks
>
Service in­
tervals
>
Reset oil change interval.

(J) CAUTION

- Do not reset the oil change interval display
unless you have changed the oil.
- Keeping to the correct service intervals is
crucial for the operation, service life and re­
sidual value of the vehicle (and especially
for the life of the engine). Services must al­
ways be carried out promptly, even if the
mileage is Low.
