Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only add the following
coolant additives mixed with distilled water.
The amount of coolant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant additive
percentage is too low, the coolant can freeze
and damage the engine.
Note
- Before the start of winter, have an authorized
Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the G12evo coolant additive is not available
in an emergency, do not add any other
additive. You could damage the engine. If
this happens, only use distilled water and restore the correct mixture ratio
with the
specified coolant additive as soon as possible.
- Only refill with new coolant.
- Radiator sealant must not be mixed with
the coolant.
- You can continue driving if the permitted
G12evo coolant additive was not added.
However, go to an authorized Audi dealer or
authorized Audi Service Facility immediately
to have the coolant replaced to reduce the
risk of engine damage.
- Due to the risk of engine damage, the cooling
system should only be refilled by an authorized
Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also provide
you with important information about
the recommended coolant additive.
