How to Completely Fix a Broken Mercedes S430 Air Suspension

If your Mercedes S430 is showing a suspension warning light, the time to get that car to the shop and fix it was yesterday. Unfortunately, suspension issues are all too common among owners of these vehicles.

To make things worse, a busted Mercedes S430 air suspension is more than just uncomfortable and inconvenient, it’s dangerous. It can reduce your car’s ability to handle and seriously increase stopping distance. Driving on a bad suspension can also seriously damage your Mercedes.

How to tell if your Mercedes S430 air suspension is broken

Even if your suspension warning light isn’t on, there are a number of indicators that you’ve got a suspension problem.

The first is that the car sits unevenly or too low when parked. Sometimes this will mean one corner of the S430 is lower than others. However, the most common sign is when the rear of the Mercedes is sagging down. When coming to a stop, does your S430 “crouch” forward? If so, it means that at least the front air suspension is worn out.

You can also give your Mercedes “bounce test.” Walk around to each corner of the car and push down hard on the bumper. If the car springs back up and settles immediately, that corner is fine. If it bounces up and down before settling, it’s time to replace that strut.

Another sign that the air suspension in your S430 may be broken is if the air suspension compressor is running for too long. Also, it may just be running very loudly. Either one indicates that the compressor is working harder than it should.

If you suspect you are having a Mercedes S430 air suspension problem, don’t wait. Take your car to your mechanic right away for a diagnosis.

The problem with repairing the S430 air suspension

Brand new, nothing rides like a well-engineered air suspension. The one that came stock in your S430 is one of those.

The Mercedes-Benz Airmatic air suspension is quick and responsive thanks to a complex network of moving parts and computers. Like all moving parts and electronics, however, they are prone to wearing down and eventual failure.

The air springs in the S430, for example, are made of a flexible rubber/plastic component that holds the air. Due to the nature of its materials, these air bags will eventually dry out, crack, rot, or otherwise tear or break.

One of the most common issues in any air suspension is an airbag wearing out or breaking. This happens naturally due to the limited lifespan of the components.

Items like the ride height sensor and compressor are also moving parts and will need to be replaced at some point.

All in all, once the repairs start with an air suspension, they don’t stop. While a couple of hundred dollars for a new air spring might not seem like much now, when you multiply that by three and consider you may still not solve the problem, it gets to be a hefty bill.

You might pay more than $3,000 to completely fix your Mercedes S430 at a dealership. For many, this is simply too expensive.
