How to Fix Your Audi A6 4F C6 Avant Rear Air Suspension Problems

Signs Your Audi’s Air Suspension Went Faulty

First things first, let’s make sure the issue lies in your air suspension. If you notice any of the following, then we have the fix for you.

Ugly Sagging at Your Audi’s Corners

When your air suspension goes faulty, your air springs can’t inflate. As such, you’ll spot some ultra-ugly sagging in the corners of your car. Even worse, you’ll ride lower to the ground. And that extra loss of ground clearance leads to expensive damage and fixes later on down the road.

Grinding and Clicking Sounds during Your Drive

When your air suspension goes out, your fans and other parts need to pick up the slack. As such, you’ll hear all that extra work. This leads to wear and tear that will cost you in the long run.

Your Audi Rides… Not So Smooth

The biggest sign. If you feel every bump and pothole in the road, your suspension’s bad. No question about it.

Remember, you bought an Audi for a smooth, luxury ride. To make full use of this comfort, you owe it to yourself to get your air suspension fixed.

What you’ll need:

• Replacement rear air suspension for your Audi A6


• A set of standard metric wrenches


• Lug wrench


• Socket wrench


• Anti-seize spray (for those stubborn bolts)

How To Replace Your Audi A6’s Faulty Rear Air Springs

1. Disconnect Your Battery. Stay on the safe side. Disconnecting your battery keeps any parts from powering on when you don’t want them to.

2. Jack up your Audi.

3. Take off the rear wheel. Use your lug wrench to pull off your lug nuts. After doing that, you’re free to remove your wheel.

4. Disconnect the airline behind the air spring. Use a wrench to unscrew the airline fitting here.

5. Remove your sway bar nut and bolt.

6. Remove the lower shock mounting bolt. Again, use a wrench for this step. Don’t be afraid to use an anti-seize spray if the bolts are rusted or tight.

7. Unplug the electrical connectors. These connectors are for your speed sensors. A simple disconnect is all that’s needed here.

8. Locate the retaining screw beneath the air spring. Use a socket wrench to remove this screw.

9. Remove the air spring from your Audi. To make this easier, you can use a prybar to move your suspension to help you access your air spring.

10. Install your new air spring. From here, you’ll perform the above steps in reverse. For extra room, feel free to use a pry bar to move your suspension out of the way. Then, put your spring in place.

11. Put the retaining screw beneath the air spring back into place. Use a socket wrench to make this easier.

12. Connect your electrical connectors. No tools needed here. Your hands are enough for this step.

13. Rescrew your lower shock mounting bolt and lower sway bar nut and bolt. Use your standard wrenches.

14. Connect your new airline to your new air spring.Remove the fitting from the air hose. Then connect the hose to the back of your air spring.

15. Put your wheel back on your car. Tighten all your lug nuts to the manufacturer-specified torque settings.

16. Lower your vehicle. You can now reconnect your battery. Start your engine and wait a few minutes to ensure your air suspension and all other parts work as they should.
