Wondering how many people have issues with the system , Mine seems to go up fine and will drop when I go a certain speed, but the button won't lower it.

 

is the door closed, clutch not engaged etc?

 

The switch would only lower mine 1/2 the time. Dealer replaced the pump under warranty and no problems since.

 

When it works & when it doesn't.

It always goes up , noticed it doesn't always display lift on the cluster , when it doesn't display lift on cluster is doesn't work with switch to go down. but will reset itself when you drive 30mph.

 

Thanks to the great staff at Porsche New Orleans for getting the issue fixed, they ordered a new pump.
