Aerosus offers brand new air suspension compressors for the Mercedes CLS (C218 /X218 chassis platforms), that replace the original compressor of your vehicle. Our powerful compressors are made by WABCO, the original equipment manufacturer of Mercedes-Benz compressors. Each one is covered by a 2-year warranty with a 30-day money-back guarantee by Aerosus. The new original WABCO compressor comes fully assembled & ready for installation, including compressor, relay & electrical plug. WABCO air suspension compressors are high-quality products for supplying air to the suspension system. As a key part of the air suspension, a good compressor is vital. WABCO compressors are known for their consistently powerful & reliable performance as well as their exceptional durability. All WABCO compressors are designed for use with 12V vehicle electrical systems & have integrated air dryers, which are completely maintenance-free. Our strong collaboration with WABCO means that we can offer the same compressor unit at a significantly lower price than Mercedes-Benz dealerships. The compressor relay should be replaced after installation of the compressor unit, as failure to do so will void the product warranty. After the compressor is installed, Aerosus recommends that you check the complete air suspension system for any leakage. The most common cause of compressor failure is a leak in the air suspension system, most likely in one of the air springs. Leaky air springs should be replaced immediately to maintain optimum compressor performance.
