√ Vehicle sagging √ Compressor works erratically or not at all √ Unusual sounds coming from compressor √ Before purchasing a compressor, please note the following: The most common reason for a defective compressor is a leak in the system, causing the compressor to run too long and too often. An excessive number of switch-on cycles will cause the relay contacts to stick together. As a result, the relay no longer functions. The result is continuous current on the compressor. The compressor runs continuously without control until it burns out. Before a new compressor is installed, all the reasons why it has been damaged must be completely eliminated. To the leak: A leak can occur in many places, for example: - Porous or damaged air springs or air spring parts (strut) - Worn seals, defective compressed air connections and chafed compressed air hoses - Leaky housings in components such as compressors, valves, air springs or suspension struts. Every air spring system is vulnerable in this way. Therefore, follow our advice to avoid any further repairs in the near future.
