If the height of a Q7, Cayenne or Touareg 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.
• If replaced in time, it is a rather inexpensive thing to do
• If not replaced in time, a broken valve may lead to a compressor failure
Triscan pressure valve 8720 29301 is a high-quality valve suitable for fixing this problem on both front and rear struts of Audi Q7 (4L), Porsche Cayenne (9PA) and VW Touareg (7LA, 7L6, 7L7).
