hi guys im a newbie on hear and love the site and everything about porsches ...just brought myself a porsche cayenne 4.6 turbo and the suspension is not working im getting the red and yellow warning lights on the dash and the car wont move of its lowest setting (bump stops). Iv checked all fuses and they all have voltage ..the wiring running up to the compressor(power in) has no voltage ..... but the compressor will work when i put an external electric supply through it direct .. can anybody help ? im really at my witts end . thanks very much . mark

Could it be the thermal sensor ? Thanks

If you bought this used, is there a chance somebody installed a lowering module? I believe it would be behind the passenger side panel in the cargo area next to the audio controller system.

thanks very much for your reply scott . iv had a look at the back of the car and i can find a small volkswagen silver (module) i think its about as big as a dvd box but its on the right hand side (drivers side) and it does look like its part of the air suspension loom . does any body on hear have any diagrams or know where i could find a diagram of the full air suspension and wiring so i can trace the fault . thanks any advise would be great .

hi guys update went to jbh porsche and ferrari specialist in the uk .. they plugged into it and it was the rear passenger side level sensor that was down .. the rest of the suspension and compressor is all fine . so just need to order a new sensor and all should be good
