4 Common Audi A8 Suspension Problems (and How to Fix Them)

The Audi A8 of the 2000s brought the car manufacturer to the forefront of the foreign luxury car market in the United States. With a combination of luxury and performance that rivaled the “other” German brands, Audi broke through and became a major player.

Part of the car’s luxury appeal was its sophisticated air suspension system. While providing an excellent ride, like all air suspensions it has proven to suffer from longevity issues. This has left owners with few good options on maintaining their Audi’s ride quality.

The A8s from this time had several common issues that affected its suspension performance.


Faulty Control Module



The Audi A8’s air suspension is controlled by an electronic control module. This module is actually a small computer that reads electronic signals from the sensors. Then it determines how much air pressure is needed at each shock.

Like all electronic parts, the control module is prone to the occasional software issue or malfunction. This might cause the the air springs to over or under-inflate. In turn, this can cause extra stress on the other suspension components.


Leaky A8 Air Springs



The air springs used to cushion the ride need to be made of a flexible material. As a result, they aren’t as sturdy as parts made out of metal.

Over tens of thousands of miles, these often plastic and rubber components bear the full weight of the car. They are destined to wear out at some point, and usually well before the 100,000 mile mark.

If kept in a very cold or very dry environment, these air springs may wear out even sooner.


Punctures or Tears in the Air Lines



Your A8 uses air lines made of flexible plastic or rubber tubing to carry pressurized air from the compressor to the air springs. These materials are prone to being nicked or cut.

No matter where you live, road debris is just a part of the life of a driver. It’s not uncommon for small pieces of rock or glass to puncture an air line.

This problem is very easy to overlook. However, it will cause the compressor to work overtime to keep the air springs inflated. This will cause early failure in the compressor if left untreated.


Worn Out Compressor


The pressurized air used to pump up your air springs is generated by a small compressor under the hood of your Audi A8.

This compressor is itself a small engine made up of tiny moving parts. Like all moving parts, it will eventually wear out.

Furthermore, when other parts of the air suspension start to fail it is usually the compressor that picks up the slack. This makes them prone to failing before they are supposed to.

How to Fix It


You can choose to fix each component of your Audi A8’s failing air suspension. This method is usually very expensive. The compressor alone may cost more than $2000 just for the part! Add labor to that and just to replace the compressor you’d be out nearly $2500.

It may seem tempting to spend just a few hundred dollars here to replace one of the air struts and hold on to that air ride. However, as they are built on an interconnected system, once one component starts to go, the others are sure to follow.

An Alternative


Wouldn’t it make sense then, knowing that air suspension is going to fail completely at some point, to just get rid of the problem entirely?

With a Strutmasters Audi A8 4 Wheel conversion kit, you can divorce yourself from that troublesome air suspension for good by replacing it with a brand new extra-sturdy coilover suspension.

Like all Strutmasters kits, this one is specially tuned for your 2002-2009 Audi A8. Our patented Glide Ride technology ensures you’ll be experiencing a similarly smooth ride to your original air suspension.

Best of all, it costs a fraction of the price. For less than $1,000 you can replace your entire suspension. That’s thousands upon thousands less than it would cost to repair or replace the air suspension at the dealer.
