    Hello Nick and everyone else,

     

    After much frustration,  I took the car to the dealership and asked them to fix my problem.   I was thinking that something was wrong with the climate control unit.

     

    Well,  the dealership got it working, but then I was embarrassed.   Instead of buying a compressor that was specifically for a Porsche Cayenne,  I bought one that had a slightly different electrical connector on it because it cost much less.   I bought part number  GPD 9641834    from Rock Auto for under $300.

     

    Well, when I connected the wires with my own connector, I got them reversed, so that is why the compressor wouldn't come on.  Apparently when the wires were swapped back the compressor started working and the system was able to be charged.  I have had working A/C since.

     

    I have checked the CAN bus and I still have the same "1299 Gateway Implausible signal" fault,  so that must not have actually had much to do with my A/C problems.  I still have no idea what is causing that code, or what it really means.

     

    Sorry I couldn't help more.

     

     

    Thank you for the reply..... i am pretty sure the gateway fauly implausible signal is a red herring as I found it on cars with working ac....I like you have tried to save money and bought a recon denso....i wonder if my wires are crossed! Thx again
