Good question. Don’t know!
have you actually confirmed that it sits differently when running and when not? (You need to have all the doors closed - an open door prevents self levelling).
obviously it will move slightly as you get in and out but it should return to the same level afterwards, when the door is closed.

 

Yep, all 100% when running. Only drops sometimes after parking and then closing door! But if it parks fine after a few days I notice right front side down and left front side up. That's why my best guess is a faulty valve block? But then why the compressor run...

 

The compressor runs to shift air/nitrogen around the system quickly. That’s what it is designed to to.
When you get out and close the door it senses the reduction in weight (or rather the the car goes up and it registers the height increase) so it Pumps air out of the shock back into the tank and brings the car back down level again.

try it with something heavy in the boot. (Trunk). (Several slabs of beer ). Go for a drive.
take the beer out, notice the car rising as you unload and the same thing happens when you close the hatch - the rear of the car will lower and you will hear the compressor run whilst it adjusts level again.

As to why it isn’t level when parked, that’s a mystery. But do let us know when you get it fixed.

 

Update: Car is back from the dealer, they kept it 2 days and tested the whole suspension system and conducted a leak test and at present found no fault... The upside is that I still have another year warranty and they said that even outside warranty now that everything has been documented and they've seen the video if something fails outside warranty they will cover it (I'll wait and see). Speaking of the warranty they replaced my sticky PCM ***** under warranty.

 

Can anybody help with this?

will 2010 Panamera S Air Struts fit on
2016 Panamera GTS??

Thanks in Advance!

 

damaged valve block to front right (driver side) shocks


hi, have you manage to fix yours ? i had the more or less the same problems as yours. passenger side increase height when parked, and driver side lowers itself at the same time. no leak and re-calibrate but still happening. they finally found damaged valve block (air line from front right cant get it tightly into the valve block hole) and change it to new one. problem solved but since then i found my passenger side is most of the time higher for 2mm - 4mm than the driver side. not sure im being too much or is it still “acceptable”. they said if its under 1 cm is still normal. what do you guys think

 

Mine is the same, some days good, some the usual self-level to the incorrect position when turned off. Did yours happen all the time? or intermittently like mine? A Porsche salesman told me he thought it could be the control module for what that is worth.
Regarding the height you have now, the manual states a tolerance of 10mm variation I recall as acceptable, however the tech can manually set values for the height when calibrating so if they can be bothered spending the time it should be quite straight forward to get it with a couple of mm I would have thought as it adjusts to the mm.

 

mine is intermittently like yours until they change the valve block to a new one. now is no problem but the left side front & back is always 2-5 mm higher than the right side. when you said the tech can manually set values for the height when calibrating. what’s that ? i recalibrate before i change the valvle block. which page in manual said 10mm is tolerable ? thanks

thank you. the dealer actually once told me that difference in 1 cm is still “normal”. mine is 2 mm sometimes, sometimes 3mm or max is 5 mm. but left side is always higher by those numbers. just curious does this happen to all panamera ? mine is PS 4.8 w 17k mileage. is it because the windshield reservoir & gas tank is 100% full ? i had them full 100% most of the time.

 

This is great. I have a question - this is what happens:
I start my car and drive it out of the garage - then make a sharp slow turn and it feels there is no suspension and it's clunking.
I drive the car for a while and it doesn't happen anymore.
My assumption is, that there is a small leak or the air contracted overnight and it takes about 90 seconds until the pressure is right.
Is this bad? Not getting any warnings.

 

My Panamera did the same thing and yes it will rise a little while you're driving but that is do to the air system trying to compensate the leak in the air strut. Find out which strut is bad and replace.
I replaced both of my front air struts even though one had failed. Its best to do both at same time if you can afford to.

 

Okay cool, thanks for the tip. I will test my air struts.

 

Greetings,
first of all I would like to thank the author for the important information shared and very much appreciated the knowledge sharing.

I own a 2011 4s panamera and I have had a recent faulty compressor on my air suspension system. I have replaced it with a rebuilt one and so far i have had no faults coming on my dashboard.

However i have noticed something I didnt before but Im not sure if this is normal or if my mind is playing tricks on me. So the scenario is I start my car, the compressor starts to fill the air reservoir tank probably for like 2-3 minutes, then air is filled in the rear suspensions of my car to raise it up a bit. Note that I keep my suspension on comfort mode, and my high level button is deactivated.

after I park my car and close all doors ( I dont switch off my car yet), i hear the compressor kicking in again for probably about 2 minutes then stops (note that car rear suspension rests and lowers down a bit before the compressor kicks in).

so basically what i wanna know is this scenario normal? Or the air reservoir should have enough air to run the system and compressor shouldnt be kicking in more often?

thanks for all your efforts.

 

Well my opinion rest on this, have you ever replaced any of your air struts? If you haven't with the year of your penny, its probably one of your front or rear shocks.
