How to check and refill power steering fluid in an Audi A6?

I noticed some noise and stiffness in my Audi A6's steering wheel and suspect the power steering fluid might be low. Can someone provide detailed steps on how to check and refill the power steering fluid in my Audi A6? Thanks!

First, locate the power steering fluid reservoir in your Audi A6. It's typically located near the front of the engine on the driver's side. Make sure the car is parked on a level surface, remove the cap and check the fluid level. If it's low, use a funnel to slowly add more power steering fluid. Be careful not to overfill.

If you find yourself constantly refilling your power steering fluid, it's likely that there is a leak in your system. Check for any visible leaks or puddles underneath your car. It's important to get this fixed as soon as possible.
