Checking and Filling
Do not continue driving and switch the ignition
off. Add coolant. The vehicle must not be towed.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
BB Electric drive: malfunction! Cooling system.
Please contact Service
There is a malfunction in the cooling system.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately.
Before winter weather begins, have an au-
thorized Audi dealer or authorized Audi Serv-
ice Facility check if the coolant additive in
your vehicle matches the percentage appro-
priate for the climate. This is especially im-
portant when driving in colder climates.
Coolant level
Fig. 163 Front compartment: coolant expansion tank
Observe the safety precautions ® page 253, Gen-
eral information.
Checking the coolant level
» Park the vehicle on a level surface.
> Switch the ignition off.
» Open the hood * page 254.
The coolant expansion tank is located in the ple-
num chamber under a cover. Slide the cover that
is located below the windshield wipers on the
front passenger's side toward the windshield and
remove the cover > page 255, fig. 162.
> Read the coolant level on the floating gauge for
the expansion tank without opening the cap.
The coolant level must be between the Min and
256
Max markings when the coolant is cold
© fig. 163
> If Bij turns on, do not continue driving
page 255.
» If the coolant level is just over the Min marking,
drive to an authorized Audi dealer or authorized
Audi Service Facility immediately.
—The front compartment in any vehicle is a
potentially dangerous area. Before perform-
ing work in the front compartment, switch
the ignition off and allow the cooling system
to cool down. Always follow the information
found in = page 253, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the front
compartment, because there is a risk that
you could be burned. The cooling system is
under pressure. When you no longer see or
hear steam or coolant escaping, you may
open the engine compartment with caution.
~The coolant expansion tank may only be
opened and filled by an authorized Audi
dealer or authorized Audi Service Facility.
~The cap of the coolant expansion tank for
the high-voltage system is equipped with a
seal that must never be removed under any
circumstances > page 256. If the coolant ex-
pansion tank is not sealed, contact an au-
thorized Audi dealer or authorized Audi
Service Facility.
—When adding coolant, it may leak into the
inside of high-voltage components and
cause a short circuit, increasing the risk of
fire.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.
Coolant loss that results in the coolant expan-
sion tank becoming nearly empty primarily in-
dicates that there are significant leaks in the
cooling system, which can lead to further
damage. If this is the case, do not continue >
