Your advantages: Much cheaper than Genuine price Cheaper than an offer from an authorised workshop Durability and safety Simple installation and low maintenance requirements 2 years warranty Important user information Even if the built-in relay is still functional, both we and the vehicle manufacturer recommend changing the operating relay. Since the relays in the box are often very similar, it is important to ensure that the correct relay is also changed. The most common cause of compressor failure is a leak in the air spring system or the ingress of dirt or moisture into the compressor. We therefore strongly recommend replacing the air filter. We offer the air filter as an accessory in our shop and can be ordered at the same time.
