I did it today and it was very easy. You must do this work in the Menu --> Vehicle Level Control. If you raise the values, the Air Suspension is lowering. Measure your original height and read the instructions, then follow the procedure until end, step by step. Don't forget to connect a battery charger.

Hi, i am attempting to do calibrate my suspension with the Durametric tool (6.204 software)

During the calibration process the car lowers its self then will not raise & there is no compressor noise.

The engine is off & i have a charger attached to the battery, no power low alarms, 11.6 V at the terminal.

Any advice at this point would be greatly appreciated as i now have the suspension fault caused by half completing the process.

11.6V at what terminal? 11.6V is a battery that is about 70% discharged.. That's very low. Is there a reason you're not running the engine? And I would be suspect of your charger (it may not be powerful enough, or it just might not be working.)

Get the battery voltage > 12.6V and try again.

What Porsche means by a Charger is something at least 20 amps or more in some cases. A trickle charger will not do the job, most are only between 1/4~3/4amps.

I have now tried with the engine running & the compressor will still not kick-in during the suspension calibration test; the front lowers then the error msg "conditions not met" appears. Oddly enough when i unplug the cable & drive around after 5 mins or so the compressor starts & the front returns to its normal position (normal now being 2" lower than the rear).

Is my car possessed by a daemon or some sort ??

Yep the second i hit the switch during the test causes the test to fail, but will raise the car.

if try to go in to Low manually i am seeing an error code 2250 seems to be a valve but i don't know which one.

One thing i have started doing is just guessing the values (i know dumb) before the car returns to normal level, don't do this.

The front is way lower than i have ever seen it before @ now won't go up.

It probably had something to do with hitting save when the front was in the low setting; saving 190 mm with low.

I think I'd try to raise it without the durametric hooked up at all at this point then. See if you can get it operating normally, turn on and turn off the car a few times, go for a few drives, then try the durametric again.
