! Ready? Let’s jump in! How do I replace my Audi A6 2003’s power steering fluid?
To replace the Audio A6 2003’s power steering fluid, follow these steps:
Find the power steering reservoir. It probably has a green cap and is located on the driver’s side under the hood.
Using a Phillips head screwdriver, remove the reservoir from its retaining clips. Gently lift it slightly and then, using needle-nose pliers, remove the clamp from the return line (the line on the right closest to the front of the car).
Place a container under the vehicle and remove the line. The old fluid will drain into the container. Once completely drained, proceed.
Remove the filter and clean it. Wait until it’s fully dry or use compressed air to dry it.
Crimp the supply line with a golf tee and add fluid. You should expect to need approximately one liter for this flushing. Then, point the supply line into the container and start the engine for two seconds. Repeat until fluid appears clear.
Refill the reservoir with new fluid and replace the cap. First, replace the clamp and line securely. Top it off to the fill line. Then, start the car and wiggle the wheel back and forth. Go back under the hood to check for bubbles in the reservoir. Repeat until there are no more bubbles.
The process should take less than an hour, especially if your Audi A6 does not require a full flush. It can be messy work, so if getting your hands dirty isn't your thing, bring your Audi to a mechanic. Let's take a look at a few of the pros and cons.
Should I change it myself or take it to a mechanic?
