Air suspension intermediate issue!!

[bertrand]

Hi,

 

My 2006 cayenne S, has been loosing suspension pressure on the front, this happened for two days, once the car switches on they seem to get back to their normal ride height and drives fine with no errors in the dash. This kept happening for two days. Last evening I put the suspension on its top most rude height, lowered it, later drove

It around and parked. This morning when I checked the suspension seems fine and front suspension hasn’t gone down. Can someone tell what can cause this crazy issue and if something needs to be checked.

You likely have a leak in one of the air springs or the valve body itself

Any idea on where to look? It stopped happening for the last few days.

A scan with a Porsche dedicated tool like Durametric or PIWIS should be able to identify the culprit straight away

 

A simple visual check may help as well, i.e., when you come out to the truck which end and side seems lower than the rest?

Thanks, will try that. I don’t have the durametric or the PWIS. May take it to a workshop or something.
