air suspension air suspension problems

hi,

 

i have a Porsche cayenne of 2006 and have some problems with the air suspension. i changed all seals and the airspring in the front and yesterday everything was ok. today i went to the car and the airsuspension in the front was down again. i start the engine and touched the leveler  to raise up the car. i heard how the compressor was working but the front suspension stay down. after a while the light for the ABS and Traction control went on and the speedometer went up to 90mph. the ABS light and traction control light stay now on and in the dash comes the message PSM failure. if i use now the leveler to bring down the car or i would try to raise it up nothing happens not even the compressor comes on. i disconnect the Battery for 5 minutes and start the car again. the compressor work but only a very short time  and the car don't raise up. i can push the leveler in every position and nothing happen. i hook up the VCDS and choose the Touareg 7L from 2003-2006 but i can only read out the ABS and it show ABS wheel speed sensor front left and both in the rear implausible signal also it showed tiptronic switch F189 implausible signal. had that something to do with the air suspension? do i need hear the OEM Software of Porsche and if it is so can someone PLEASE send me a link where i can buy it? i changed 2 years ago the valve block. can i change the lines from the valveblock from the front to the rear that i get air pressure on the front springs to see whether a leak is there or how i can get air in? if someone have technical information about the air suspension Please send it to me and i will donate again.

 

many thanks for every help
