22" and Air Suspension Faulty
2004 Cayenne Turbo
Tried to install a set of 22" wheels and get an error "Air Suspension Faulty - Workshop" message. I thought this was due to the settings in the PCM so I went to the menu and it only has choices up to 20"
Is there a way with the durametric to fix this?

The wheels themselves will not cause an error. Sometimes I'll get an error after jacking the Cayenne up, that usually clears up after a short drive. This still happens even if I put the suspension in service mode before jacking it up.
The warning can also be completely unrelated to the wheels or the process of installing them.

Right now the suspension is in the low setting and i can't adjust it. It also appears that I cannot put it into service mode. Basically, it seems stuck at that height.
Does this influence any ideas?

Did you disable the PASM before you jacked up the car? If not, do a search on RL, others have made the same mistake and there are solutions out there.

Yep, had 22in wheels on my O4 S with air and no issues. Now have 22's on my 05 Turbo with no issues.
When I put the 22's on the turob just jacked up each corner and swapped em on with no problems.

The larger wheels should be running a lower aspect ratio tire so the rolling circumference is about the same as it was before. Because of this, the car doesn't really need to know the exact size of the wheels you're running - just select the largest option in the menu, which in your case is probably 20s. If you disconnect the battery ground strap at the front of the driver's seat for about 10 minutes, I bet it restores your suspension functionality. To lock the suspension, put the car in Normal height and hold the air suspension height toggle forward for about 5 seconds until you hear a beep and see the "disabled" message appear on the dash.
The suspension will not move when any of the doors are open so if you were trying to troubleshoot it with a door open, you'll keep getting that "not permissible" message on the dash. If you need to move it with the door open, like if you have a laptop plugged into the OBD2 port and don't want to be sitting in the car, either bring it out through the window, or you can manually close the door catch with the door open (just don't forget) and the suspension will move.
When I installed the 22x12s on my widebody, I just selected summer 21 and haven't had any issues. Tires are a 315/30-22, which are within about 1% of the rolling circumference of the original 295/35-21s that were originally on the car on the 21x10 wheels.

Circling back on this and it appears it may be fixed.
It never ceases to amaze me how the proper batteries, and battery condition, can solve problems that are seemingly unrelated.
I was suspicious of the batteries anyway and the car is new to me. So, I did some investigating and ended up replacing both batteries with proper Interstate batteries and after a drive it appears the suspension faults have resolved themselves. One of the batteries installed was not the correct size and appeared to be a recycled unit and the other battery was very old.

No, the suspension was not disabled.
After clearing the codes with the durametric, there is one code that will not clear. It's 1437 "Control position not learned (no or incorrect basic callibration)".
Even though I'm not trying to lower the car do I need to go through the documented process of lowering the car with the durametric? Is there anything else that could cause this?
