Relay for compressor for Mercedes Benz W212 S212 and CLS C218 X218 air suspension Please note that when shipping to a country outside the EU, you may incur additional costs (customs duties, VAT). To ensure that a new compressor functions safely, the relay must also be replaced before installing the compressor. The relay offered is for the Mercedes Benz used. * You can find the exact models and years of manufacture in the vehicle list above. Even if the installed relay is still functional, both we and the vehicle manufacturer recommend changing the working relay. Since the relays in the box are often very similar, it is important to make sure that the correct relay is changed. The most common cause of compressor defects is a leak in the air suspension system or the entry of dirt or Mois.
