Allroad Suspension Repair or replace?
2000-2005 Allroad air ride suspensions commonly fail and are usually referred to as “high maintenance.” Many owners become frustrated when they begin to experience issues with their Allroad suspension system and realize the high cost of replacement parts and labor. Many want a quick fix. Is it a leak? Where is the leak? Is it the compressor? Consequently, diagnosis of the exact problem can be very time consuming and costly.
The first obvious indication that something may be wrong within the system is when the instrument cluster (control panel) light comes on, indicating a fault in the air ride system. Another common situation is as follows: The front or rear levels of the vehicle are uneven or completely bottomed out. When the engine is started, the dash lights begin flashing indicating that the vehicle isn’t at its selected level. The compressor kicks in, and you wait approximately 5 minutes until the light turns off and the selected level has been achieved. This is often seen as an inconvenience and accelerates the wear factor of the compressor, shortening it’s lifespan.
Common weak links in the system are as follows:
O-Ring Mating Area Air Leaks
There are several o-rings at the bottom and top of the shock absorbers and air bags. Over time, these o-rings may shrink and cause air to leak during suspension compression.
Plastic Air Hose(s) Pressure Fitting Area Air Leaks
Over time, the plastic tubing that runs thru the pressure fittings may shrink, become brittle, or lose pliability. During air system operation the pressure fitting isn’t able to hold the plastic air tubing properly, causing a leak. These leaks are hard to find and usually occur near the connection points where the air lines meet the air bags.
Air Bellows (aka air bag spring) Air Leaks
Constant suspension flexing, weather-related moisture, or old age can cause the air bags to crack and leak air.
The instrument cluster (control panel) light will usually light up and indicate when your level sensor isn’t working. A level sensor(s) may have failed if the light on the dash won’t turn off. Over time, electrical components wear out and fail.
Compressor – Ride Height Pump
Due to an existing leak(s) within the air system, the compressor may constantly have to run to try and maintain the correct level, accelerating the wear factor of the compressor and shortens its lifespan. If you choose a particular level and the light continues to blink, this may indicate that the compressor is worn out and cannot generate enough CFM to raise the vehicle high enough to reach the setting.
Over time, the integral circuit board and/or other electrical components may wear out and fail.
Many owners choose a total replacement system that eliminates the air ride system. The replacement system we use has a limited life time warranty and will be a savings over the stock air ride system.
