tank
fig. 146 using the outer
markings 2
fig. 150. The
coolant level must
be between the markings 2 when the engine is
cold. When the engine is warm it can be slightly
above the upper marking.
- When you add coolant to the expansion tank.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank.
If you must add coolant, use a mixture of water
and coolant additive. Audi recommends mixing
the coolant additive with distilled water.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can result
from the coolant boiling due overheating
and then being forced out of the cooling system.
WARNING
Note
Do not continue driving if the coolant expansion
tank is empty. Do not add any coolant,
because air could enter the cooling system
and damage the engine. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.
