Volkswagen ID.4: Brake fluid specifications

Volkswagen has engineered a specially formulated brake fluid designed to match the precise requirements of the Volkswagen ID.4 brake system. To ensure consistent braking performance and long-term reliability, Volkswagen strongly recommends using only brake fluid that complies with the VW standard 501 14, which is specifically optimized for vehicles like the Volkswagen ID.4.

Before adding or replacing brake fluid in the Volkswagen ID.4, always verify that the specification listed on the container fully matches the vehicle’s requirements to avoid compatibility issues.

Brake fluid that meets the VW standard 501 14 is available through authorized Volkswagen dealers or certified Volkswagen Service Facilities, ensuring correct formulation and maximum safety.

If brake fluid conforming to this exact standard is not available, a high-quality alternative that meets DIN ISO 4925 or US Standard FMVSS 116 DOT 4 CLASS 6 may be used temporarily in the Volkswagen ID.4.

However, it is important to note that not all brake fluids meeting DIN ISO 4925 or FMVSS 116 DOT 4 CLASS 6 share identical chemical compositions. Some may contain additives that could negatively affect internal brake system components of the Volkswagen ID.4 over time.

For this reason, Volkswagen recommends exclusively using brake fluid that explicitly meets VW 501 14 to maintain optimal braking performance, durability, and safety of the Volkswagen ID.4.

Brake fluid that complies with VW standard 501 14 also fulfills the requirements of DIN ISO 4925 and FMVSS 116 DOT 4 CLASS 6, ensuring high boiling point, corrosion resistance, and system compatibility.
