What type of power steering fluid should I use for my Audi 80?

I am getting conflicting information about the type of power steering fluid to use for my Audi 80. Some sources say to use ATF (Automatic Transmission Fluid) while others say to use CHF (Central Hydraulic Fluid). Which one is correct and why?

Your Audi 80 requires CHF 11S specification power steering fluid. It is important to use the correct fluid as recommended by the manufacturer to ensure optimal performance and prevent potential damage to the steering system. Avoid using ATF as it may not provide the necessary lubrication for your vehicle's power steering system.

I have been using ATF in my Audi 80 for years without any issues. However, after doing some research, it is recommended to use CHF as it is specifically designed for power steering systems and provides better lubrication and protection. I would suggest switching to CHF for optimal performance and longevity of your power steering system.

As an Audi mechanic, I have seen many cases where using the wrong power steering fluid has caused damage to the system. I highly recommend using CHF for your Audi 80 as specified by the manufacturer. It may be a bit more expensive, but it will save you from potential costly repairs in the future.
