Nitrogen not a must. But recommended. Inhibits internal degradation of shocks.
place to buy shocks? Suncoast, RMT, dealer (you'll be broke), arnottindustries.com, aerosus.com.

Hope this helps.

 

I try to remind myself that I own a PTT by driving it once every two months. My cayenne diesel gets 700 miles range so no point driving the PTT.

 

Found my issue
broken front passenger strut
little worried car is sitting to low 4 a tow

 

Rock Auto sells Arnott struts. Don't forget to find a 5% discount code....

 

thx 4 info
was going to get the strut from suncore ($420) and follow CIAKA diy thread
Issue being nitrogen

 

​​​​​​I bought the proper fill "Schrader type" valves. I did not buy a filling apparatus valve it's kind of expensive. Maybe if someone local was willing to split the cost...

The image shows a dual stage but the description reads single stage. Was trying to figure out if I could buy a dual stage version, (which distracted me far enough), besides the fact that when I changed mine I did not have a leak....

 

If you want to fill with nitrogen, you can go to welder store and ask for a tank with gauges and nitro2 to fill the system.
Online, you can buy the air line adapter (about 45 bucks). Once you have it all, you will still need PIWIS2 so that you can open proper valves to get the nitro in.

I almost wish that porsche would have a valve on the air tank itself, so one could simply connect nitro tank to it and fill up to 17bar (I think thats the level, but dont quote me).
Having refill fitting on the air tank would make this so much easier, and would allow to drain moisture that can accumulate, especially in cold climates.
But no, too easy I guess. I think I saw someone somewhere, make a fitting on the air tank, had it jb welded. I am sure works just fine. Thought about it for some time, but never got motivation to try.

 

Foxwell NT510 Elite has filling function I believe, (never tried because didn't have a leak when I replaced driver front). Wonder about iCarsoft....

That's a great option @ciaka because the control valve is quite expensive...

 

Linked snap-on tool say 17bar so you're probably correct.
I haven't seen the fill port on the car, what kind of connection is it? threaded, quick connect, etc.?


edit:
adapter like this I guess?
Looks like schrader valve on one end and some fine thread metric on the other? :shrug:

Of course disorganized me can no longer find my set. Sigh...

 

Here's the deal tho... The air system isn't closed right? The compressor pulls air from the environment, so after a month of the car doing suspension adjustments, how much nitrogen is going to be there? Or is there a closed portion where having an initial and permanent nitrogen charge is needed?

 

It is not a permanently closed system, no. It pumps the nitrogen into and out-of the tank so it should not need to add any air from ambient. But they all do eventually.

 

I pump my rear tires to 44 PSI per tire placard. Converted to BAR that is just a tick over 3, or 3.034 BAR per Google. Let's use the nominal pressure of 16.5 BAR, (17.0 BAR is max), which Google tells me is 239.312 PSI. Are you sure it's an open system? It's closed, it's just that springing a leak or working on more than one corner at a time causes you to lose the pure N2 that came from the factory, aka there are many ways one can contaminate the system.

I was watching Curling on the Olympics, and I realized that the high pressure in the system would likely prevent water from freezing, since it is adiabatic, so maybe one of the other contaminants? (Sorry about not rushing to proclaim my potential mistake)....

 

Well, here I am again with the dreaded chassis system failure. My scanner just shows sport mode not available. I already replaced the front struts and that cured my problem previously. Now I am stumped. It just came on as I was driving down the road and I continued to drive home. All four struts seem to be sitting at the normal level and nothing drooped after sitting for a week. I bought a replacement relay because it was cheap and I’m going to try that first. I figure it cannot hurt. The air pump appears to be working. Every time I open the drivers door the pump kicks on for just a few seconds. It has done that since I got the car. I am thinking valve block? The rear struts don’t seem to be a common point of failure and like I said all four corners are sitting normally. Any other suggestions?
