front suspention noisy

Hello Alfonso! My name is Branden. I am one of the owners and technicians at Silver Arrow Autohaus. Unfortunately you probably have a leaking strut for your suspension. Your vehicle has an air bag full of compressed air that it uses for the suspension. When the cars leak like yours while parked it is usually because of a leaking air bag. It could also potentially be a faulty valve or a leaking line/hose but these two are less common. I would be happy to inspect your vehicle for you at no charge and see if I can narrow down the cause of the leak for you.
