Anyone have a diagram or can explain where the relay is for the wipers on a 2006 Cayenne?
I continue to have fuel issues. My car looses all pressure when off. I ran out of gas today with 6 gallons left in the right tank. The pump is new. When I pull the fuse to the right pump it runs fine. When I pull the fuse to the left pump it dies. Is there another way to test if the right pump is actually working.
I had that fixed a month ago. I pressurized the fuel line to the tanks and at about 20psi bubbles came up from one of the pumps. Thought I had my answer, but then when I continued to add more pressure bubbles came from the other pump. I turned the pressure in the direction of the fuel rail and it held. I need to figure where my pressure leak is coming from. Any ideas are appreciated
My cayenne is loosing fuel pressure when off. I have replaced both pumps and pressure regulator. I have ordered a new filter. What is the problem with installing a check valve on the fuel line? Seems like a simple fix. Any comments appreciated
I am loosing fuel pressure when engine is off. I have replaced both pumps and the pressure regulator. I suspect that one of the many fuel lines inside the tank is bleeding off pressure. How can I test this.
I have replaced both fuel pumps. From videos I have seen it seems that if it was a bad back flow valve the loss of pressure would be slow. This loss is instant. I suspect it is a vacuum hose problem. Can someone point me in the direction of what hose it could be.
