EAS No Faults Showing...

[Doo]

Fixed EAS and been delighted that it's staying up... Except yesterday, after not really using the car for about a month (one or two short short runs) I took it out and went to lower the suspension from full height to standard. Nothing!

Went through all the heights, but it's stuck up at full height so I assume the exhaust valve is jammed!

I removed the electrical part, then the valve (pretty certain it was the exhaust valve, closest top one to windscreen) and the car stayed put, but I did notice a water droplet which suggests there's a problem with the desiccant).

I tried tapping the side of the block, but still nada so looks like another strip down job

Any advice? I rather think the water has caused this with the valve not being used for about a month!

Hi doo ,You know if its in gear or hand brake or foot brake is on or it thinks a door is open,IE tailgate,it can inhibit movement...and a blocked exhaust on valve block will slow things down....

It was in P and I often lower it with & without the parking brake. All doors closed (inc boot) so I am fairly certain it's the valve jammed.

Ahh well, it's not like I've never done it before or anything

Back into the breech again doo!!!

Im just saying theirs more than a valve ,,,Be four you go in ham fisted wi a hammer ...Does it lower with the laptop plugged in

Valve at top rear of of valve block is diaphragm valve NOT the exhaust valve. Exhaust valve is the top one nearest the front of the car. Diaphragm valve applies air pressure below diaphragm when compressor is running, to close exhaust port and allow compressor to fill tank. Do not confuse exhaust valve and exhaust port.

Thanks Wammers, looks like I got my ends mixed up.

Something must have gone wrong with the desiccant because it was fine a few months back.

But if there is water droplets in one valve, then I suspect there will be water in the system...

I would not worry overly about a little moisture in diaphragm valve. When compressor is powered the diaphragm solenoid is pulled. This applies pressure to underside of diaphragm to seal exhaust outlet and allow compressor to fill tank. Air passes along fill/exhaust gallery through drier and to tank via NRV 1. When the compressor stops and power is dropped from diaphragm valve, the compressed air holding the diaphragm shut is vented into the harness via the 4 mm pipe. The compressed air in the fill/exhaust galley passes out to atmosphere past the diaphragm valve but through the drier in the opposite direction to filling. This blows any condensate out of the desiccant and out to atmosphere. Check that all doors are closed, no movement up or down can take place with a door open. Also car cannot drop whilst compressor is running.

 

[Doo]

Checked doors & boot. All seem tight and no message on the dash to suggest otherwise!?!?!

It was working perfectly a week ago and now the button is pressed, the light flashes to show it is obeying instructions, but it doesn't carry them out. No fail warning so is it possible it "thinks" a door is open? The interior lights go out ok when the door is closed. Delay with ign off and immediately with engine running.

I had a similar problem once mate.
I changed the 1.0mm solenoid and and its o-rings including the square one on the blue wired coil as they were rock hard, that did the trick for me .

The whole this was brand new not that long ago, "O" rings, NRV's ( ) and all. It was working fine, sitting up for weeks at a time, but serious lack of use (bike so cheap to run) and it's gone tits up

I was just about to go out with the laptop and do a check when the rain came on like Loch Ness tipped upside down in one go

Suns out again, so cup of tea, sarnie and see if it's good to go. Need the car tomorrow evening as a trip of 30 miles on the cards

Hope you find the problem mate
mine was a simple fix when i swapped the solenoid underneath the blue wired coil. Hopefully you get it sorted mate.
Good luck

I'll have a look at the workings of the blue one and pinch the same one off the spare I have...

Went out with laptop, plugged in but didn't start the software....

35mph was showing on the dash and the top & bottom lights were showing on the switch.

I pressed it anyway and down she went

Da fuq??

Fired up the software and looked for faults, 2 showed, FL sensor and vehicle moved so I binned them, restarted and this time it showed about 300 faults

Cleared them, same again. So I switched off ign, restarted & rebooted. Same, 300 faults. Messed a bit, rebooted and no faults.

Watched the initilization do it's thing, no faults showing, checked faults, none found.

However, just before all this, it was at standard height, then automatically went to full height (no input from me) and I pressed the button to lower for it to do it again

Played with heights, full up, down, full down, etc. Then did some off roading (steep embankment, over a stump and repeated several times in forward, reverse, left & right, no faults showing.

I left her on standard rather than full height, but I wonder if perhaps it "is" the FL sensor as it has showed up a few times as faulty but she always seems to show correct height on the computer and will adjust up or down in bit increments without any issues whatsoever

 

[Grrrrrr]

I've never played with the EAS unlock software but I believe hundreds of faults usually means bad communication with the EAS computer. I think people usually point the finger at the ODB port. You have checked that connector behind the passenger kick-panel?

Going to high and staying there is usually a soft fault. I guess an intermittent reading from the FL sensor might give that? @kurtjohnson10 or @wammers will know. Or maybe @pwood999.

Vehicle has moved means nothing in fault terms. It just means that an height sensor is showing a different reading than it was last time the ignition was on and the system was active. Make sure that all the bit count readings at all heights are not to close to the maximum or minimum bit count for that height. This info can be found on the info and instruction sheet for Easunlock.


From that showing minimum and maximum bit counts for each height.

-------------------Front-------------- Rear
Extended-- 120-180 --------105-150
Standard ----95-150-----------85-130
Low -----------75-140---------- 75-120
Access------- 50-110---------- 50-100

Bit count should not vary more than plus or minus 2 side to side particularly at front.

From memory, there is about 30 bits between each different height. I think the left side is two bits higher than the right and according to the above I am well within parameters.

Today, I went out to find her listing ever so slightly at the rear left, not much and to be fair she is laden (about 400 kilo's of equipment) and soon as I fired up she corrected the height. Went to visit a friend & collect my lad. Drove home and twice (each time at a roundabout) she went from standard to full height with no input from me and the height locked.

The full height lamp was flashing that it wanted to go higher, so I pressed to go to standard height while driving at around 15/20mph and the lamp stopped flashing, so I pressed again and it flashed at standard height until down she went until the next roundabout.

Looking like the FL sensor is faulty as it always initially shows as a fault, but disappears when tested a few times...
