Hello. This is my first time posting as this is my first issue with my 2006 Cayenne S and this is also my first Porsche. The vehicle had an aftermarket radio in it when I purchased it and I changed that radio for another one that supported Apple CarPlay. both units are made by pioneer and after looking at the backs of them it appears to be plug and play. I changed everything out and fired it up and everything was great. No issues or errors and the sound worked fine and calls worked fine. The previous installer used only twisted ends and electrical tape to secure the wiring so I took the wiring apart and used wire nuts to make sure nothing came apart while it was being installed and for longevity. After starting the car back up, I received a brake proportioning fault and an oil pressure fault and it told me workshop fault as well. I pulled fuse 40 as I heard it resets the system and plugged it back in. The brake proportioning fault is gone but the oil pressure fault remains. I double checked my wiring work to make sure that I was not missing anything and nothing had come back apart. Everything is indeed attached and plugged in. Now that I have finished my long-winded story, was this fault caused because I knocked something loose or because I left the fiber optic cabling unplugged for too long. I noticed that there was a red light coming from the input and of the fiber optic cabling a couple of times while I was rewiring it. Do I just need to reset this system using a better method or do you think something is wrong with it? Any help would be appreciated and I intend on donating to this forum and website as it seems to be a true source of knowledge and help for the DIY Porsche enthusiast. Thank you in advance and I look forward to your responses.
hey guys , past couple months my cayenne s 04 air suspension warning light has been on, after a minute of driving. when i try lowing or raising the vehicle, the front end works fine but the rear suspension stay stationery in raise mode. even when using the diagnostic to force the rear to lower nothing happens .fault codes in the level control system was for rear suspension holding valve . so i went ahead and replaced both rear holding valve and recalibrate the suspension. it worked fine for two months .now the warning light is back the rear suspension is stuck in high and not lowing. new fault codes p1780 , 1400 im unsure what to do. do i replace the valve again or is there some else wrong what do you guys think?
