As promised, here is a full write-up on how to lower your Cayenne factory air suspension with only a Durametric cable. You do not need a lowering module or lowering links to do this mod. So if you already have a Durametric cable, then this is the cheapest and easiest way to lower your Cayenne.

Since there are over 30 pages of detailed steps, it is not conducive to attaching the images to this thread. Instead, I generated a full page PDF.

You can download the full document here: Durametric Cayenne Lowering Tutorial V2

For the "on-the-go" version, here is the brief text format:

Using the Durametric v.6 (download the lastest), it is pretty easy to recalibrate the suspension once your have your independent wheel measurements - although it is not intuitive.

I have used this method a few times before since I lowered my OEM module in a similar manner.

As a overview from memory:

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.

 

Here is the "correct" way (as per Porsche) to measure the points on your chassis and then enter them into the calibration fields. You should use these points and the values as measured, when calibrating a Techart lowering module since it already compensates for a lower ride height .

Thank you Renaissance Man. Great info. You just saved me $1400.

 

I did this about a year ago. The height change is minimal. I would say 1/2 inch at the most. I measured the before and after on all four wheels. Definitely worth it for free, but not the same drop as the lowering module by any stretch. Great write up!

 

Cool! Maybe you can save me $1K+ in the near future. How about those free TIG classes?

Thanks for the props! I knew their had to be other people who did this factory lowering. I was somewhat dumbfounded when others seem to doubt that this was possible- despite this being well documented on the Touareg with the same air suspension setup.

I wonder why you wouldn't get the full drop if you entered in an additional 25mm on the calibration? I was actually able to drop it "too much" and ended up with a tuna-boat sort of ride and had to bump it back up 3-5 mm with some fine tuning. FWIW, I have seen a glitch in the factory module, where it randomly decides that it does not like the correct values and changes the range.

Since I just got my Techart module last October, you can view my demo video floating around since it was dropped using this method and judge for yourself.

 

Nice job Kent. Very detailed and clear instructions. Thanks for doing this. This is actually very useful to all the people with the Techart module, or anyone considering one.

 

RM, I did it again tonight. Worked great. You made my day ... thanks very much for taking the time to post.

Now for the next project. I am going to try to convert my headlight switch to auto. The switch swap is easy .. but I have to program to interior luxury lights I believe. It is listed under electrical .. I just do not know how to change the code.

 

Cool! Glad to see that you were able to get the drop you wanted without too much effort.

The coding is the trickiest part. If it is not listed under "Adaptation", not sure how much help I will be. Taking this to PM to see what we can figure out.

 

Thanks man for this information. I lowered the car even more with this guide now. I went ahead and added another 25mm and also I have a lowering module so it went even lower.

I have attached some pictures in loading mode.

 

Also thanks for information on the o2 bung extender.. installed and no more Check Engine Light!! *THUMBS UP*

 

NICE CTT bro

 

Nice pepper! Seriously nice stance - that is exactly what this thread needed - more stanced Cayennes! I meant to tell others that I also tweaked my Techart lowering module settings (in 2-3 mm increments) since I did not like how high the rear sat after the Techart install. Now the rake is much less.

By the way, how do you like those Nitto tires?

Cool! Glad to hear it helped. I try to only give solid information.

 

I like them.. they definitely grip.. unfortunately these tires came on the car so I don't have anything to compare them to.

 

how does this lowering affect suspension performance though?
Is there a deterioration of performance in either of the modes (comfort, normal, sport)?
Wondering what (if any) are the down sides of doing this.

Thanks.

 

There is another way I have been working on. You have to use Vag-com via a VW toureg then swap suspension ecu's. This way lowers a lot further. Not a fan of durametric compared to Vag-com.
