Air Suspension Problem?

67Rob · Mar 8, 2015

I know there are lots of threads on the subject but the specific issues with mine are:
1. The height adjustment switch sometimes flickers between normal and motorway or highest and normal on start up.
2. When stationary at traffic lights/junctions etc the front goes up and down slightly for a few seconds.

Any ideas?

1) Look for corroded connectors behind the kick panel in the passenger footwell.
2) Normal.

Thanks, will have a look asap.

It is probably nothing. If you've parked on a slope or uneven ground it takes a moment to work out which height it should be at. The flashing is it making its mind up and moving to whichever it decides.

The dancing at lights is also common, although if really bad might be something. I think someone traced theirs to a faulty driver pack.

Driver pack will not normally make the lights dance, nor should it happen when parked on a slope. The only time a lamp flashes is when it's the target height for a change of height when you get a solid light at access and a flashing one at target height.

I think he means the car is dancing at the traffic lights?

Hi I think the dancing at traffic lights is because you have put your brakes on put lode on front so air goes in to lift it, then you take your foot of brake and it adjusts its self to its correct ride position
I do hope you understand what I mean. That is my thinking of it anyway

Height changes are disabled when braking, but other than that you are right, it levels when you take your foot off the brake.

Every time the vehicle speed drops to 1 MPH both front valves open to equalise pressure across the axle. If because of load or the fronts are slightly maladjusted or a combination of both there is more pressure in one side than the other the front will drop slightly. It will then rise as the air is replaced to level the car.

Well it seems to be ok at present, hasn't done the light flicker since last Thursday.

The only thing is the stationary thing where it feels like the suspension is 'breathing', moving up and down slightly.
But if, as Datatek says, it's normal then I'll not worry about it.

Are you sure about this policy?
