'06 Cayenne S - all 3 driving program lights stay illuminated
I have a problem with my '06 Cayenne S, and was wondering if anyone has seen this problem. When I start the pepper, all 3 lights next to my driving program rocker switch (center differential lock, low range and rear differential lock) come on steady - no blinking. They stay on, and any attempts to change the programs are futile (brake fully depressed, neutral gear, pressing the rocker up or down). There are no other indications of a problem - no warnings on the dash, or indicators that I might be in low gear or in any off road driving program. Also, the car appears to drive fine and is not in low gear, and is not jumping around on pavement because of the differentials being locked.
Does anyone have any ideas on how to clear this up (other than heading to the dealer)? I've already checked all the fuses that have to do with the transmission, differentials or transfer box. Thanks.

I don' think it's an issue with the switch (due to a coffee spill), so I think I'm off to the dealership soon.
I ripped the switch apart just to see if everything was working correctly in there. I thought there might be an IC chip that may have gone bad... but its just a switch and LED lights. My ohmmeter tells me the switches are working fine, so the problem appears to be elsewhere. I may poke around a little bit before I call the dealership, but I'm not seeing something obvious like I had hoped. Thanks for the input, though!

That is PNCA8902A code, usually a sign before catastrophic failure.
My 06 cayenne base works perfectly fine, Id be willing to switch ya to relieve you of the headaces.
By the way, have you updated the cardan shaft, coils, plugs, and tubes?
