Hi friends,

I have a problem, and I start to get very !"#$$# with it, because I didn´t find the same problem here and fix...

About a month I change the orings in the NRV, and the diaphragm. (no more dance in the lights)
I get the "flying carpet" ride for +- 2 weeks... but now I still have the Harsh ride and also this symptoms:
1. The car with engine running, the height is more higher than it should (Normal, Access, or High way), but if I turn off the engine and before opening the door, he goes down to the +- correct height of the manually select position.
2. If I selected off road position, the led keeps blinking, but never stop.
3. Sometimes, when the car is on the normal height, (after doing step 1), I get the access led blinking and he goes up to the normal position.
4. Sometimes, when I start the engine he didn´t go up like it should (my weight), but goes down?

For what a read here, it looks a drive box issue, I try a new (used drive box), but didn´t fix it.... so a thing it´s not a drive failure...

So I have to check the EAS ECU, and height sensors! Right? or should first rebuild the all BV? (also the most inexpensive).

Of course, no leaks, air gauge installed.... :doh:

Help! thanks!

PS: I forget to write, its the front where step1 is more evident, the height in the rear is more correct....

I would initially get it to a LR dealership and get them to run the callibration on all 4 corners - it sounds like one of the height sensors is giving an incorrect reading (could have been damaged when you originally had the leaking O-Rings - driving on the bump stops is not good for them). If it is damaed, you can replace the part easily enough yourself - but again the dealer will need to calibrate it. Unless you know anyone who has Roavacom.

Thanks Dan,

I am almost buying a new pair from the front.....but what is stoping me for doing that, is why with engine running the height are incorrect! :x I think it could not be "only" the height sensors.... must be something that I can´t find...
Also in the past I swap the sensor, left to right,...

EAS basis is no leak at all.
I'd start with a VB rebuild

Agreed, have you tried opening and closing a door. This forces an auto level, incase of loading or unloading.

It can be your non return valves

There is free software and cheap cable / instructions to make cable here on this board, see the forum for software & diagnostics. You can read and reset errors , calibrate height +++ with this software. See also http://www.rswsolutions.com/index_easunlock.htm

Hi friends,

I start to loose my Pro EAS :crybaby2:

New BV rebuild, New "used" drive pack, same problem :evil:

Dance in the lights, the front normally dove after cutting of the engine... the "normal" height of the Front is +- 830 mm, with engine running.
Goes to +- 800 mm with engine off...
When selecting heights, from HW to normal, the rear have "little" move compare to the front.

With the car one week park, no drop in height, no air tank pressure lost...

I had read/ search a lot in here , but did find anything who helps me before buying new stuffs, and what stuffs?

The problem is the harsh ride and I think that my new front shocks are dead (2 months)....

So, what I should do? new front sensors? new EAS ECU? Try "new" valve block ? Springs :naughty:
Sorry.....

Edit: When I try with a good used drive pack (from a friend off mine, when he was rebuilding is VB), and I try everything, but the car don´t go up, I have a pressure gauge and the compressor stop at +- 10 bars, but no way to go up. I put my "old"and the car goes up, the "new "used and also work... ( this info can be important, or not...)

Thanks

I'd give it a good calibration.
I bet that as mine, it hasn't been calibrated for 13 years or so.
On mine it looks like left sensors are fighting with the right sensors. :lol:

Are you sure you have connected the air pipes going to air bags correctly.

A blocked air dryer will also cause compressor to run long, o rings on dryer also leak.

Hello Friends,

Last week end, I drove the car with High way position manualy blocked, no dance in the lights, and also a more confortable ride.
Before home,I unlock the EAS, and I have dance in the firts lights, that I stoped.
So I think it´s time to buy a new pair of sensors? Did you agree?

thanks

Have you done a EAS calibration procedure with a Testbook ?
Try that first because even with new sensors you have to do it.
