• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coo lant additive to 60% .
• When adding coolant additive to your cooling system, remember:
-We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
eng ine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig. 223 Engine
compartment: Coolant
expansion tank
Vehicle OP-eration
Before you check anything in the engine compartment,
always read and heed all WARNINGS=:> & in "Working in
the engine compartment" on
page 280.
-Turn off the ignition.
- Let the engine cool down .
- Place a thick rag over the coolant expansion tank
=:> fi.9. 223 and carefully twist the cap counter -clockwise
=> & .
- Read the engine coolant level in the open coolant expan­
sion tank=:> fig. 223. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max" marking.
The location of the coo lant expansion tank can be seen in the engine
compartment illustration =>
page 281.
To obtain an accurate reading, the engine must be sw itched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System =>
page 31 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
t ime to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system . In the event of
coolant loss , the cooling system should be inspected immediately by
your authorized Aud i dealer . It is not enough merely to add coolant .
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating . .,
