First off, I just want to say I'm a newbie with Porsche and purchased a 2005 CTT a few months ago.  I had to replaced my passenger upper control arm so I just jacked it up with the air suspension at the lowest loading level and took it apart removing the strut (no, I didn't put it in "Service Mode"... didn't realize that this was the proper procedure until after the fact I started search forums to help me with my issue... and in fact, still haven't figure out how to put it in this service mode.).  Anyway, when I put it back together again and drove it around, I get an error saying that my air suspension needs maintenance and notice the height levels on each wheel seem to be a bit off.  I read somewhere that I need to re-calibrate it with the Durametric scan tool.  So I hooked it up and started the procedure provided on the Durametric --> Level Control--> Adaptation window.... but when I click on the "Read" button on Channel 1, it automatically states, "This channel does not support adaptation."  If I try to read any of the channels, I get the same thing.  Is there any other way to just reset everything to just default?... anyone have any suggestions? Thanks in advance for any help anyone can offer.  -Jay

OK, first you need to measure the vehicle's calibration point values and determine what the values should be:




Nest you need to connect your Durametric system:


1) connect your ODB-USB cable and open up your Durametric program.

2) browse down the tree on the left side to "Level Control" and select it

3) then select "Adaptation" to be on the calibration screen

4) select "read" . The box below the channel number will say "wait..." Your air suspension will go up and down.

5) when the suspension stops moving and the box changes from "wait.." to "enter". Enter the measurement (in mm) from the wheel displayed. Believe first is "FL" or Front, Driver. Then hit "save". If it accepted your entry, the value in the box will change from "enter" to "learned". If not, then will have to reenter or restart the program/laptop.

6) click the channel "up" button to move on to calibrate the next wheel.

7) do this same step to the other 3 wheels

8) Once all 4 wheels have confirmed "learned", press the channel "up" button one more time to channel "5". Enter "1" to save changes. If the system accepts your changes, it will say "control position learned" in under a minute. If it just sits there and does nothing, you may have to start over from scratch. Sometimes it takes a few times to stick.

9) You will then hear the air suspension adjusting to your new settings - hopefully that means air purging. Enjoy.

Thanks for you quick response, JFP, but I can't even get that far... when I click on the "Read" button on Channel 1, it automatically states, "This channel does not support adaptation."  If I try to read any of the channels, I get the same thing.  I have a ticket open with Durametric as well... I'm crossing my fingers that this is a Durametric program issue that they can help me resolve.

I used the attach files option as suggested instead.  :huh:


Did you attempt to read other channels as well?  Never mind, I see that you have already tried that.  I would say that the system controller is having issues or for some reason the Durametric system cannot communicate with it.
