"l!::7": Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate service or repair . Driving
with a low-oil-pressure indication is likely to
inflict severe damage to the engine .
• Switch off engine and check oil level
If the indicator light turns on and the mes­
sage appears, the oi l pressu re is too low.
.,. Pull off the road .
.,. Stop the vehicle.
.,. Turn off the engine .
.,. Check the engine oil level c::> page 21 S.
.,. If the engine o il level is too low, add eng ine
oil

sure warning symbol. appears no longer
in the display before you start dr iv ing again .
.,. If the engine o il level is correct and the indi­
cator light still turns on, turn the engine off
and do not continue driving. Seek professio­
na l assistance .
@ Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication

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 i nternal engine components, a ll in­
ternal comb ustion eng ines consume a certa in amount of oil. Oil consumpt
ion varies from
engine to engine and may change significant ly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
<=> page 196) consume more oil during the
break -in pe riod than they consume after o il
co nsump tion has stabilized.
Under normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscos ity
of the oil, the RPM (revolut ions per minute) at
wh ich the engine is operated, t he ambie nt
temperature and road conditions . Fur ther fac­
tors a re the amount of oil dilut ion from wa ter
condensation or f ue l resid ue and the oxid a­
t ion level of the o il. As any engine is subjec t to
wear as m ileage builds up, t he oil consump­
tion may increase over time until replacement of wo rn components may become necessary.
W it h a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alte rnative
to regu lar and frequent check ing of the o il lev­
el, see
Note .
If
the yellow engine oil level warning symbo l
in the instrument cluster
I!!! lights up, you
shou ld check the oil leve l as soon as possib le
<=> page 215. Top off the oil at your earliest
convenience
<=> page 215.
A WARNING
-Before you chec k anythi ng in the engine
com partment, always read a nd heed all
WAR NIN GS¢
& in Working in th e engine
compar tment on page 211.
{(D Note
Driving w it h an insufficient o il level is like­
ly to cause severe 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 lev el in
your engine at regular intervals , pref­
erably each time you refuel, and alway s
before going on a long trip. .,.

218 Check ing and filling
fig . 188. With a cold engine, the coo lant
l evel should be between the "min" and
"max" markings . When the engine is warm ,
the leve l may be slightly above the "max"
mark ing .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
9 page 213.
To obtain an accurate reading, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning l ight in the Auto-Check System
9 page 15 w ill
illum inate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a le ak in the cooling
system . In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
s ealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scald­
ing from hot coolant by followi ng these
steps .
- Turn off the engine and allow it to coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefu lly in
a counter-clockwise direction w hile ap­
plying light, downward pressure on the
top of the cap . -
To avoid being burned, do not spi ll anti­
freeze or coolant on the exha ust system
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator repair fluid may adverse ly af­
fect the funct ion and pe rformance of you r
cooling system and could result in damage
not cove red by your New Veh icle Limited
War ran ty.
Adding coolant
Be very careful when adding engine coolant.
