Well after a couple of weeks I’m back to working on my Air ride. I removed the new front block valve, took it apart found the plunders stuck, corroded. So I purchased a new one again ( I suspect the shop I sent it to replaced my new one). Our local Land Rover dealer is three weeks backlog. Anyway I replaced the front blocking valve. Cranked the car, compressor came on, rear end lifted compressor shut off front never moved. I did a hard reset. Cranked it up rear end lifted front never moved. Thought when I jacked the front up to change the rotor could I have gotten it out of calibration?

 

You wouldn’t have messed up the calibration, but if the truck is on bumpstops now, it’s possible that you’re outside the range of travel of your height sensors. Are you getting any error codes?

You could try jacking the front end up just a little bit, then start the car and see what happens. If that’s the problem, jacking it up a bit will bring it back within the travel limits of the sensor arm.

 

I did jack it up about 3 or 4 inches. It acts like it’s not getting air to the front valve. But I know it is because I removed the line off the valve and had air pressure. Note , I took the ride height lever off and moved it up and down trying to get the valve the lift it. Could that have done any damage?

 

You took the lever off? Or the height rod off? To my knowledge, the lever does not come off the sensor. The height rod does come off and once off, you can move the lever up and down. It shouldn’t damage anything and should be back within range once you put the height rods back on. Although... if you did it with the engine on, I don’t know if it would store any sort of error codes and prevent the front from raising. If you’re getting a bunch of lights on the dash, you could try clearing the codes and see if it resets itself.

 

I did a hard reset on it. And the cluster says it’s in extended mode return to normal height after clearing obstacle. But the front doesn’t raise I’m at a loss as to what to do next

 

Where should I start checking? Like I said earlier the local and rover backlog is three weeks out

 

So what happens when you try to “return to normal height” by moving the height selector switch down? Anything?

 

I mean, it definitely sounds like a sensor issue. Is there any chance you removed them and could have reinstalled them on the wrong side? I think the electrical connector is supposed to point down. Do you have a diagnostic tool to read the values that the sensors are outputting?

I would remove the valve block again and recheck it as you say you have air there. You have the connections around the correct way? The valve block is controlled by the EAS controller but as the rear goes up I would check the connections to the front valve block as they maybe corroded.

 

Not really sure how the suspension switch ( on the console) works but when I push the lever to the rear the message says in extended mode return to normal when obstacle is cleared. The only diagnostic tool I have is a scan tool II not sure if it will show me anything. Tomorrow I think I will take the air supply line off the valve block and make sure I have air there then air coming out of valve block to air spring etc.
