How is the 4-level air suspension system described?
The principles of the suspension/air suspension system and the description of those system components which are identical in the 4-level air suspension system are described in SSP 242. The contents of this self-study program are supplementary to the contents of SSP 242. The 4-level air suspension system in the Audi allroad quattro Introduction
What are the most common problems with air suspensions?
A faulty compressor is also a very common problem with an air suspension. As we just went over, the compressor works to keep the air springs inflated. Oftentimes, a compressor malfunctions because it’s overworked, meaning that it runs more often than usual.
Can a air suspension system function without an air compressor?
The suspension system cannot function without it. If the compressor is failing to come on at all, then that is a sign that it has either failed or it is having an issue. The air compressor is what provides the air suspension system with compressed air required for it to function.
What causes air to leak from air suspension?
With time, the rubber components of these parts will deteriorate, creating holes and tears and causing air leaks. There are various warning signs that your air suspension is suffering from an air leak. For example, you may experience a bumpier ride because a damaged air spring can’t absorb the shock from bumps in the road.
What causes a problem in an air suspension system?
The compressed air within an air suspension system contains moisture that can accumulate and lead to severe damage. This issue is caused by a malfunctioning air dryer assembly, a part designed to remove moisture from the compressed air.
What happens if your air suspension compressor fails?
If the compressor is allowed to continuously operate with abnormal sounds, it may eventually result in damage to the compressor that will cause it to fail. When the compressor fails, the system will have no means of inflating the air bags and the vehicle will have a disabled suspension. 3. The compressor won’t come on
How can I tell if my air suspension is bad?
Checking the suspension system for physical damage like rust is the easiest way to determine if there’s too much moisture in the compressed air. This problem can also affect leveling capabilities, the compressor, or overall suspension performance, so you want to check the stance and performance of your vehicle as well.
What to do if there is no power to the air suspension pump?
If there is no power going to the air suspension compressor, check the air suspension fuse and relay. Here is a picture that shows no power to the air suspension pump. The next step would be to use a professional diagnostic scanner such as the iCarsoft MB II to check the fault codes for the Air Suspension Control Unit.
