So a week ago it showed the error then after 6 restarts its ok, after 800 miles it failed in a different way

I heard some strange occasional knocking noises from the front then the front went to loading level or lower while the rear stayed up. Same error "Air Susp Error"

In the shop awaiting the good news

Hopefully it won't be a major issue. My PASM has always worked fine. I did have 4 people in the car and a large load of fishing gear recently, and when we got out at the cabin the suspension released air as the weight was removed... it sounded like 18-wheeler brakes. Other than that, no issues.

A fault code check is recommended, could be a faulty front height sensor for instance.

Dealer reports that the drivers side airstrut blew the "airbag out", his words "there was shrapnel everywhere".

Parts are in Germany so it will be a few days, estimating $1800 to rebuild the strut.

Best part is that all parts of the Air Suspension are covered by my extended warranty EXCEPT the airsprings themselves

Car has never been off road except for sand a long time ago, mostly light duty cycle.

RFM ever heard of this ?

If you mean that the metal cover just below the air bellows is blowing in pieces, yes!

Does that mean a complete new strut ?

Also what is the cause ?

Air suspension struts are constructed as a complete piece, i should say more, depending the mileage of the car it is recommended to replace the struts on the same axle. Factory extended warranty covers the struts over here. The cause is probably weak spots in the metal or damage in some cases, i have seen 14 month old struts with this damage. It is definitely not a common issue.

Thanks RFM I appreciate your replies very much

There is a procedure to do with PIWIS after installing the struts, bleeding and filling the system and adjusting the ride height. Bleeding and filling can be done without PIWIS IMHO, but to adjust the height without the tester is not possible, it is in fact the same process as replacing the control unit. Replacing the struts can be done on a lift if possible.

They comes probably by foot, unbelievable that Porsche US have no stock, the struts are available here not in BO.

OK got it back today, just over 3 weeks

Seems fine

I will post the bill when I am near a scanner

Drives well, 4 wheel alignment most likely helps
