Hello all

I have just replaced the spheres on my car. Ride all lovely again

However, the sls valve will only allow the car to raise. Even when manipulated manually with the link to the Arb disconnected it will not lower.

The valve was working beforehand but now it appears not to be. Does it look like a faulty valve? No leaks and when commanded to raise the suspension goes up quite quickly even on idle so I assume the pump to be ok.

As an aside, the big bore return pipe into the reservoir has no flow. Is the big bore the correct one to look at? My car has 2 return pipes into the reservoir. The small bore one I assume is for the ASD.


Any thoughts?

Many thanks
