I'm sure there is a thread already out there...
But I'm wondering does the air compressor for the air suspension overheat? Also where is it generally located?
2012 by the way...
Reason I asked, driving around... The temperature is getting up there. I get the chassis level system failure.... Basically picture of the shock and it's red. Lucky I was close to my house when it happened, so I was able to safely get home.
I turned off the car, turned it back on... Read somewhere to check if the compressor kicks on and it did, cycled it through the whole comfort, sport, sport+.. everything works. High level on and off... Everything works fine.
I will be spraying some soapy water on the air bags itself to look for any leaks.
But other than that... Does the air compressor over heat? Am I over looking anything?
The fuses look fine not blown...
I wish I know close by with some sort of scan tool for these Porsches... Because I found out my current scan tool isn't up to par for this.
Any help will do, I want to see if I can fix it myself before sending it to a Porsche specialist.
The compressor is underneath the car, right next to the rear differential. And yes, it does deactivate for bit after running too much, but will cool and then come back to life.
Also, the pump uses outside air to fill the air cylinder, which was factory filled w/nitrogen, but the pump does not pump the nitrogen... The air cylinder and valve body are really what do the actual inflation actions.
I would suggest there is probably very little of the remaining nitrogen in any system that has been in operation for more than 10K miles, as the system cannot selectively vent only air from the tank.
You can surely refill w/nitro if you have it handy... Lastly, rebuilding a compressor is not too hard, providing the electrical motor elements (brushes) are not spent... I have done perhaps a dozen now...

Notice the temperature "sniffer" sensor on the left side of the compressor installed in the vehicle. This detects ambient temp near the compressor. Check to be sure the sensor is not damaged, disconnected or missing.

Update!
So a friend of mine was able to lend me his Autel scanner. As I scanned for any fault codes, and cleared majority of these codes. I checked what was the current values of the air suspension. Seeing that my air compressor still works, I sprayed soapy water on the bags for leaks and checked visually what I could for any loose connections or rotting/rust lines and connectors. Everything was good for a 2012.
But what I did noticed was the values for my rears were uneven as if it was calibrated. Compared to "factory" spec the values was off by a lot. I set everything back to "factory" spec and began my little journey of getting that ideal ride height and still be able to use sport and sport plus etc etc... (interesting rabbit hole) learning a ton about this car, and using my friend's Autel scanner. But I will return his scanner once I know I don't get any weird fault messages from this my car. So pray for me 😂

curious to hear of your continued exploits... as you noted and are learning, the process for setting suspension height is far from straightforward and simple. My left rear is still in need of some final adjustments, but fear doing this as it will - at least in my case - turn into another two-day journey. and in the end, be about the same as it currently is... this is surely not for the perfectionists out there!!!
