Is it possible to 'level' the car using the air suspension?

Hi,

I have been known to sleep in the back of the D4 and I plan to do more.

Sometimes if the ground is uneven or sloping it can be a problem getting the car level.

So I thought that it might be possible to individually control the air suspension so as to level the car. Or even, since I am sure that the car has sensors for 'levelness' Very Happy it should be possible to ask the car to level its self?

Apologies if this has been covered, but I did try to find it... honest! (If it has been covered, I would appreciate a link to it please Very Happy )

Easy with the IID Tool yes as you can program in the 4 corners and then put back to default in the morning Thumbs Up

That's perfect! Thanks Famousfive... I was under the impression that the IID tool could only do it by axle.

Cheers

I thought if you park somewhere and switched off, it'll automatically endeavor to level the vehicle after a minute or so, (just to frighten passers-by).

If your on a slope and want to get the car level you need one of these

Great bit of kit Thumbs Up

Fully automatic.. just press a button and it will level its self ( as well as lots of pre set suspension heights )

Although that initially looks exspensive i can see it being heavenly once in use. Looks well thought out too.

That was my understanding also?

Self leveling when parked? I'll test it and get back to you, but I can't say that I have noticed...

WRT the XLifter, Thanks for linking to it Wiggs, it looks really good but I won't be getting one for the following reasons:
1. It is VERY expensive and would be used only rarely
2. I think that (bearing in mind point 1 above) I can get away with fore-aft leveling which is available through the IID (which I already have).
3. The Xlifter has writing on it which basically say 'for off-road use only', and (since it is semi-permanently attached to the car) I wouldn't feel comfortable driving around with it for insurance reasons.

I intend therefore, that if I need to camp on some kind of a slope, I would park so that the car is level side to side, then fit the IID and level up the fore-aft slope. Then before driving away I can reset the suspension and remove the IID. This is nowhere near as convenient as the XLifter, but I think that it will do for me.

Many thanks for the replies everybody!

You can control individual corners with the IID tool

Thanks for this, gentlemen. But do either of you have a link to any info on how to do it? I have looked at the Gap IID instructions and, if it is there, then it is not clear to me I'm afraid...

From faq on Gap website https://www.gap-diagnostic.com/faq/

Is it possible to manually control the air suspension?
Or, can the IIDTool help when the suspension becomes inoperative? Can it close any specific valve for any corner and keep it closed while you limp off the trail?

Yes. For example, when an air strut fails, the suspension ECU detects a major fault since it is not able to raise the corner. In some cases, it lowers all corners to the bump stops. The lowering may be caused by the air leak itself since on normal operation, corners are adjusted in pair.

To manually control the air suspension, proceed with the following:

IIDTool Menu->Service Test->Suspension->Test Valve->Adjust Front, adjust to the desired height
IIDTool Menu->Service Test->Suspension->Test Valve->Adjust Rear, same as above
Each corner can be adjusted independently if needed
Keep in mind that raising both axles using Adjust All is not recommended since it takes much longer to reach the desired height. This is because the pressure equalizes when all four corner valves are opened (air goes from the front airbags to the rears) thus increasing the time required to raise the front axle.

If you are raising the vehicle significantly, the compressor may need to cool down before it can pump additional air in the system.

Once the desired height is reached, exit Test Valve mode and disable the suspension: IIDTool Menu->Service Test->Suspension->Build Mode

When finished, simply put it back into customer mode by calling the Build Mode function once more: IIDTool Menu->Service Test->Suspension->Build Mode

Not raising all four corners will put the vehicle out of balance and this can cause a safety hazard. We do not recommend driving an unstable vehicle but it can be useful to recover the vehicle with a defective EAS while offroad. Do not drive an unstable vehicle at high speed.

Thanks for that FamousFive - I had seen that bit but hadn't linked it in my mind to the fact that you can us that technique to adjust the corners.

Cheers everybody for the replies Smile
