Hello Guys,

On my 2009 cayenne gts, I have an error message regarding the suspension.

I can no longer raise or lower the suspension.

And for a few days the car has been very low. The error message has been there for 3 weeks (I don't drive much)

I did various tests and passed the diag.

Error 1397.

The pump works when connected directly to the battery but the air does not reach the suspensions.

Thank you in advance for your answers.
