Have you noticed that the height of your Volkswagen Touareg 7L seems lower than normal? A defective pressure valve may be the reason.
The residual pressure retaining valve is the part that holds the air pressure inside the air suspension strut. It wears out and brakes with time causing air leaks. As a result, the vehicle can’t be steered up and down anymore. What is more – if not replaced in time, a broken valve may lead to a compressor failure.
Pump my Car pressure valves are a high quality and yet inexpensive solution of your suspension problems. This new part fits the front air strut. An O-Ring and an airline fitting are included to simplify the installation.
