FAQ

Q

Why does air suspension experience sinking?


A

Air suspension sinking is usually caused by air bag leakage, loose air pipe joints, or poor electromagnetic valve sealing, resulting in the system being unable to maintain air pressure.

Q

What causes the air suspension to inflate for too long?


A

Possible causes include compressor aging, pipeline leakage, water ingress into the air tank, or desiccant blockage, all of which can slow down the pressure increase.

Q

What should I do if there is an abnormal noise when the air suspension is running?


A

Check if the dust cover, bushing, top rubber, etc. are aged or loose, and replace the relevant parts if necessary.

Q

How to handle the air suspension warning light?


A

First, read the fault codes to check if it is a sensor, control module, or airbag fault, and repair or replace them in time.

Q

Height imbalance after replacing an air suspension component?


A

System height initialization or calibration is required to ensure consistent height of the four wheels and avoid sensor errors.

Q

What are the consequences of water entering the air suspension system?


A

Water ingress will corrode the solenoid valve, block the air pipe and dryer, leading to system failure. Timely drainage and sealing check are required.

Q

Is it normal for winter air suspension to malfunction?


A

In low-temperature environments, rubber air bags harden, reducing compressor efficiency. It is recommended to use low-temperature antifreeze pneumatic oil and perform regular maintenance.

Q

Can the air suspension be manually raised/lowered?


A

Some models have a manual adjustment function; if not, the height can be manually adjusted via software or a diagnostic tool.

Q

Does air suspension leakage necessarily require replacing the entire air bag?


A

Not necessarily. First, confirm whether it is a problem with the trachea or connector. If the surface of the airbag is aged or broken, then it needs to be replaced.

Q

Does the air suspension system require regular maintenance?


A

Yes, it is recommended to check the system sealing, dryer filter element, and air pump operating status every 10,000 kilometers to prevent failures.
