If your vehicle is riding lower than normal this usually indicates a problem with the OE compressor. Noises coming from the part are another sign for compressor issues. As the compressor is responsible for the air supply to the struts, a faulty one means that the entire air suspension system stops functioning. A replacement is urgent, but it’s also important to check your suspension for any other defects that might have caused the old part to overwork and wear out faster.
Usually leaks from the air springs or a defective relay lead to compressor malfunctions. We strongly advise you to check both of your air springs before installing the new compressor. You also must replace the old relay, otherwise you will void the product warranty.
