Hey guys, having an air suspension problem, every corner of the car lowers and raises apart from driver side front wheel, it will try and raise and lower but kick out a suspension fault, also makes a strange ticking noise then locks me out and tells me normal height only. Ive had a garage look at it and a fault for valve block was displayed, had the block changed and its still doing exactly the same thing garage wants to check the wiring to the valve block but stange to be a wiring fault as only one wheel is affected but i havent been back yet due to having a new baby and lack the time at the moment. Im wondering if anyone has had a similar situation, I can force it to Lower and raise if I keep turning the car off and on, sometimes the car comes up with extended mode when trying to lower the car and I have to reset the suspension with the toggle back to normal and do a restart Fault only occurs when the driver side wheel wants to adjust, self leveling on the rear is absolutely fine and has adjusted when I've put weight in the back and passenger side wheel adjusts freely I've had a new compressor fitted a few months ago aswell This fault happened before and I didn't use the air suspenion for a few days and the problem disappeared for a month but its now come back for good it seems Sorry for the long post trying to fit in as much information at possible lol

Just to add, when the car lowers it'll display air suspension fault and raise itself

If the car raises slowly it won't always tick at me as its raising
here's a link to a video i uploaded on YouTube

I have no leaks in the air bags either, ride height stays the same over night and even over a couple of nights just the usual adjustment when turning the car off and locking it

 

What are the codes?

The ticking is just the valve blocks opening/closing the valves. This is more common when there is reservoir pressure and the valve blocks have to regulate the air in spurts. When running on compressor air only, they dont tend to click because the raising is slow.

Almost sounds like the front valve block could be plumbed wrong with the lines. Or it could indeed be wiring. I had a wiring issue and had to run one new wire from left wheel well over to the block. I never found the actual damage since the wires run under the radiator.

 

If it's just that corner, sounds like it could be a height sensor issue

 

That's what I was thinking and hopefully it's that as it'll be an ideal fix, I'm planning on putting a second hand one in at first to see if that fixes anything, if not ill have to do what was mentioned earlier about a wiring fault, i do not remember the exact codes I had, but I plan on fitting the height sensor over the weekend and go from there

 

What did you scan codes with? Do you have a tool such as the GAP that can calibrate the EAS? If not, your fitting of the sensor will be futile.

 

I wasn't the one that scanned the car, i took it to a land rover specialist whom scanned the codes in front of me and condemned the valve block as the codes was associated with the valve block, no ride height sensor faults was there, they fitted a new valve block and it made no difference, they said they wanted to go through the wiring for the valve block after that but since then my Mrs got induced and we had our new arrival and I'm planning to rebook the car in but all the specialist in my area are fully booked untill January.

 

I didn't scan the codes i originally took to a specialist whom scanned the car found the fault code for the valve block and condemned it, they decided to replace the block to find that it made no difference at all, they want the car back to check the wiring, all I've been told that if it's one wheel it's more than likely a height sensor but I did not have a code for one, all the specialist in my area are fully booked until January and I havent had the car back due to having a new arrival.

 

This doesn’t sound like a height sensor issue. The only thing controlling air flow to a strut is the solenoid in the valve block and the pipes.

I also would suggest checking the valve block wiring and that the valve blocks are plumbed correctly. Reversing the pipes can cause only one strut on an axle to articulate. There is also a history of chaffed wires running along the front bumper, usually causing problems with the valve block and parking sensors.
