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?

 

Zero issues for me after going form stock 21s to 22s (and the overall roiling diameter of the 22s is taller). Might be a coincidental error (?)
Maybe try disconnecting battery?

 

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.

 

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?
