Does lowering the air suspension affect reliability ?

[grltnr]

i was wondering if lowering the suspension on the cayenne turbo affect the reliability of the suspension? in other words, does lowering it cause more stresses, forces, etc which will compromise the longevity of the air suspension..? thanks in advance for your input

my guess is everyone will say no. but I think YES it does cause more stress on components that otherwise would not be under normal conditions at factory height.

i don't have the schematic diagram of the air suspension, so im hoping this can be answered on the board.

it depends how the suspension is designed..

does it act like a coil over system where height can be adjusted without compromise to the strut itself, or perhaps like lowering springs that forcefully compress the stock shocks ?

this may be a bad comparison but you get the idea..

does anyone know?

go to www.teile.pl and you can see the hole porsche cayenne build up....

the cayenne air suspension is a combination of air bags to lift and lower the cayenne and a hydraulic suspension ... the hydraulic suspension is connected to an oil extension.... when you lower down the hydraulic suspension let flow some oilback to the extension reservoier....
and the hydraulic suspension is adjustable in 3 modes to let them react fast mid or slow......


so you can drive in low mode 50.000 miles on a good street and the suspension isstill fine
you can go 10.000 m8les in the dirt and your (hydraulic part of the) suspension is dead...

I've got 65K miles on my CTT and I've never had any suspension related issues.
I also had the TA module installed about 15 K miles ago with zero problems

Good question! I drive with it at the lowest level (1 above loading). I've not had any issues thus far.

I also have the TA module and drive in the Low level 90% of the time. This means that the car lowers itself to the Loading level every time I lock it. It then raises back up to the Low setting when I get back in. That's a lot of up and down and still no issues.

i did this and i took it back the next day and had them take it off you need to buy a module taht is your best bet.
