Hello all....This site has been very informative as I continue my search for a clean used S class. I am looking at an s430 with pulse ventilated seats. How does the pulse function work? I cannot get the pulsing to continue and create a massage.....they only seem to adjust the inside of the seat when I hold a button down, but when I let go the action stops. I am wondering if the feature is broken or not. Any thoughts? Thanks!

 

i am wondering about that too, cuz mine dont pulse, my thought is that maybe its a bad pump or loose hose
