Audi Q3: Cooling system

Coolant

The engine cooling system is filled with a mixture of purified water and coolant additive at the factory.

This coolant must not be not changed.

The coolant level is monitored using the indicator light. However, you should occasionally check the coolant level.

Messages

The following messages may appear depending on the vehicle equipment:

Turn off engine and check coolant level. See owner's manual

The coolant level is too low.

Do not continue driving and switch the ignition off. Check the coolant level.

  • If the coolant level is too low, add coolant. Only continue driving once the indicator light turns off.

Let the engine run at idle for a few minutes to cool off, until the indicator light turns off.

Coolant additive

The coolant additive is made of anti-freezing and corrosion protection agents. Only add the following coolant additives mixed with distilled water.

Checking and Filling

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.

Checking and Filling

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.
