Had a thought this morning while driving.

Imagine driving over tiny pea gravel in the road. Very subtle but this is the bumpy feeling that i can feel now. Not bouncing up and down or anything, just feels like you're driving on the worlds smallest cobbles. I'll be looking at my height sensors at the weekend as discussed but i wondered if my shocks are in good order. If i had bad shocks, would that cause problems with the height sensors?

Usually you'd bounce a car up and down to check a shock. Since we are cursed with air suspension and can't do that, is there a way to diagnose or do you just take it off and have a look?

Why can't you bounce it? On something primitive you'd have bits of bent wire and a shock, we've got bags of air and a shock. The bags do exactly the same job as the bent wire, just better. What the problem might be is simply calibration. If you've got one corner trying to go higher than the other three, that will make the suspension on that corner harder so you would feel every little bump and ripple in the road.

Ok. Will have a look at the sensors first port of call then. Just working my way through everything now that i've had the bushes done again. Potentially had one problem masking another.

Passenger sensor didn't appear to be Linear anymore. So i've swapped both the fronts around.

So, the last problem ive got is i reckon the compressor is running longer than usual.

Ive put a spare compressor on but that seems to be the same. I am 100% leak free. When it blows up, it stays up and doesnt move a millimeter. Confirmed by removing the delay timer and measuring.

It seems to take ages to put air back in. For example, if i move it from standard to extended, it goes up straight away obviously using whats in the tank. Then the compressor kicks in to refill the tank. This is taking approximately 1 minute. Same goes for moving between low and standard. Is 1 minute about right to replace the air used in a height change?

Never checked that. As long as compressor fills the tank from empty with door open in 8 minutes, that's good enough for me.

Could do with a benchmark if someone wants to change a ride height whilst timing their compressor for me. :-)

Im just ruling out it struggling. Might be some resistance somewhete making it take longer. Dryer?

Ray recently found that his desiccant had turned to concrete (https://rangerovers.pub/topic/709?page=2) and was restricting the flow, maybe yours is the same?

This was my thought so i looked in the dryer first. Desiccant like new. Like polystyrene ball size. All free moving. Then there was a bit of filter on top, then a metal grate and then the spring. I maybe should have taken the bottom pipe off and blown through it to check resistance. Should there be any?
