Ok, so I forget where I read about the brown wire mod, I believe it was on this forum but I can't find anything that has to do with the mod to keep the cayenne in the loading level while driving. I looked under the front passenger seat and saw that there was a connector that had a brown wire going to it, looks like it had been snipped at both ends, previous owner probably cut the brown wire. It looks like it's been resoldered together but I wanted to get more information about this "mod" before cutting the wire and testing it out. I'm going to be sticking my brother in the back seat to find out if any of the wires coming from the rear suspension module are sending a signal since I don't have a service manual to see if I can pull that plug or install some sort of resistor to keep it from reading the proper voltage. Anyone cut this brown wire here and if so what happened? I'd assume you get some annoying error in the dash about a compressor error

No one ? Sometime within this next week I'm going to be probing the rear suspension ecu to see if I can find the voltage wire that sends the signal to raise / lower the vehicle at x speed. If I find this and it works I will let everyone know. I can't find the schematics anywhere online for it so it will be a tedious process of pulling each wire to test should be fun lol, I'd still like to get information on the "brown wire mod" if anyone has it. I know there was a talk about the PIWIS tester being able to do this, my friend that has one at his work is looking into what he can do with it to see if he can re-program it or not I know there was mention of being able to do so on the European makes to 20mm

That's what I ended up doing last night, I dropped it down to load level in the low level so now normal is the old low

Good luck but you are talking about it as if its a discrete component problem. You would be better to look at the height sensors on the struts to physically move them.

Good luck! Your brother must be a brave man!
