EAS - Feature or Failure!

[ytt105]

I've owned 5 Range Rovers and now a D3, last 3 Rangies with EAS and now the D3 has EAS, of course.

So, I have a fair bit of experience with these suspensions systems, but have not been able to understand, WHY!

Why do Landrover engineers think its a good idea to have the car level itself all night when I'm tucked up in bed.

I DONT care if its not exactly level!


On the last Rangie (P38) I rewired the air suspension fuse to be 'powered' from an ignition source instead of the permanent live feed. This worked well. I'm considering doing the same with the Disco.

Any comments?

I remove the main 20A fuse prior to jacking then refit it prior to starting with no ill effects.

You could possibly do that, but I rather suspect your time could be better utilized doing something different that has a tangible benefit.

You must have another problem cause mine levels itself about 1 minute after I get out and that's where it stays.

I dont have a problem, that I know off, but WHY?

What tangible benefits are there for it doing it.

As for why not, every bit off air released from the system has to be replaced by the compressor. The less demand on it the better for longevity.

Please, anyone know WHY!!!

[CaverD3]

Because.

If your car is doing this as you describe I think you do have an issue.

My RRS is parked on a sloping driveway and once if has sorted itself (usually during the switching off process) - parallel with the drive not the horizontal it sits there without further levelling.

Such a luxury vehicle can't be seen sitting askew if there's a slow leak in the system! Why opening a door triggers wake-up and level checking is another mystery considering the safety aspect of the vehicle lowering when about to get in.

LR have relaxed the re-levelling rules on the latest Vogue & Sport.

[ytt105]

I have described anything!

I just want to know WHY!

Because..... seems to be the best answer yet!

Air under pressure will eventually escape any containment vessel. Especially a flexible one. So it's a given that the car would, at some point, stand at an angle if there was no self-leveling, causing owner-anxiety, much chortling from the Toymotor mob, and outright laughter from the Defender boys as your Latte on the dash tips over ... :wasntme:

Your post is confusing you say it self levels itself all night while you are tucked in bed, well as said mine only does it once, I have been sleeping Alongside it for the last 3 weeks and haven't heard it.

As for the reason the Landrover engineers do it , well my understanding is the ADR rules state the air suspension vehicles have to self level for the head lights to be legal, or similar to that effect.

Sorry EAN, but people are concentrating on me stating that I dont believe it is a good system to self level overnight. I don't have a problem, that I know of, (I don't sleep next to the car, I use the bedroom). What I want to know is WHY.
Your comment re the ADRs could be close to the money, but why do it all the time instead off when the car is started. My quick look at the ADRs only talked about headlight levelling.

Let me state right now, I LOVE the EAS, I've had 5 vehicles with it, starting with a 1993 Range Rover, couldn't think of buying a car without it, I'm a FAN.

But please, why self level when I've decided I don't need the car at the moment.

My guess is the system detects the weight of the people getting out of the car , as the systems stay active for several minutes after the ignition is off for the computers to go to sleep, I guess the removal of the weight causes the system to level.

To be honest it's not something I have even considered but that's my best guess as to why.

Cheers Ean.

How do you know it is self leveling, ALL night?

Ean is currently travelling, and that is why he is sleeping with his car AND his wife.

Now, if you are sleeping in your bedroom, how do you know the car is continuing to adjust itself during the hours you are asleep?

As has been suggested, if your car is releasing air, or running the compressor hours after it has been put to bed for the night, then there is some sort of problem.

However, if, as I suspect, it does a little jiggle for a min or two after you have said goodnight, and then closes its eyes, well, have you ever watched a dog get comfortable? Around & around, then down & fast asleep for the night. ;)

Maybe it does it to take the stress off the bushes and other suspension components when it's static??

[superquag]

My Classic does a similar thing... the EAS ECU wakes up every few hours and checks the suspension height, levelling if the numbers are out. Then back to sleep.

I inserted an on/off switch in line with the interface plug/socket set, put it in the driver's seat mount. This gives me the option of turning OFF the ECU, thus saving air overnight... or freezing the suspension whilst driving. - I do this to save compressor wear, and,,,

'Because'.

:p:p:p

[Dougal]

My classic a year older than James' doesn't relevel until switched back on. I did switch out the delay timer relay with a normal relay, but I don't think that's all of it.

But yes this is all about appearances. A luxury car can't be seen sagging to one side.

I am finding it really difficult to get my D3 tucked into bed with me.

Also, mine levels once and stays there. It is a great feature, really settles the anxiety associated with my OCD.
