An engine running in the appropriate temperature range will perform better and last longer over time. Non-Audi coolants may not cut it when it comes to protecting your engine. Audi coolant is engineered to work with the metals, rubber, and plastic components that make up your Audi's cooling system.
Plus, a 50/50 premix blend is available to help reduce the hassle of mixing distilled water and concentrate. So if you think all coolants are the same–know that they’re not. Don’t risk it with off-the-shelf brands that can possibly lead to an expensive repair.
