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.
