2012 958 sport steering wheel to multi function steering wheel
Ok, this is turning out to be more difficult than I thought. My car has the sport steering wheel and I bought a used multi function steering wheel on ebay. The used wheel is from the same year car. Neither wheel is heated. The swap was easy but the buttons don't work. I read somewhere (can't remember now) if I stayed with the same year (not trying to upgrade) the swap would be plug and play. Well.... It's not.
Has anyone made the swap successfully? What do I need to do? Do I have to replace the switch assembly behind the wheel? Right now I have a four stalk assembly. Cruise control, turn signals, wiper/washer and multi function.
With the new multi function wheel I really only need three stalks. I can eliminate the multi function stalk but it doesn't look like it is as simple as just removing the stalk and its components. It looks like all the stalks are on one common circuit board so it looks like I have to replace the whole thing.
I should have done more homework but I got lucky finding this steering wheel in my color leather and with the multi function controls.
When I get everything squared away will I need to go to the dealership for coding? Sonnen told me they didn't think it needed to be coded because they didn't have instructions for it. They thought it would be plug and play.
Argh!

It may help to know what year your Cayenne is, but I think I know the answer. I have done the swap a few times on a Cayenne (958.1) and on a 991.1. My goal was to add in the heat, so in all of my cases I needed a new clockspring and programming.
Now in your case you are not adding new features, but the buttons are different. I also know that there are different programming (coding) for the multi finction vs sport. So I think you will need to have it programmed at the dealer or with someone that has PIWIS.

I fixed the title. It's a 2012. You are correct ,I am not adding or subtracting any functions. Do I need a new clock spring? One with 3 stalks?

I am thinking that you do need a new clockspring. Porsche has many different clocksprings and I do remember multi function or no multi function being options in choosing a clockspring. If you had multi function, you could swap a sport wheel with no issue. It is the extra wires needed in the clockspring that yours may not have. You will definitely need coding if the clockspring is changed.

I'm looking at the clock springs on sonnen and there are A LOT of options.
1. It looks to me like I want a combo switch not a multifunction switch right? Because the multi function will be in the wheel?
2. I can get it with or without a distance sensor. Is that part of the parking sensor system. My car has the parking system.
3. I can get it with or without radio control. My car does have a radio.
4. With or without voice recognition. I don't think my car has voice recognition so I assume I want one without.
The rest are self explanatory
Thank you for your help

I think its this one you need:
Clockspring
I think Porsche uses this one for almost all options except for heated. But you may want to call Sonnen to confirm.

Would this one work? https://www.ebay.com/itm/Steering-Column-Switch-Signal-Wiper-Lever-95861301300-Porsche-Cayenne-958-11-16-/302830612851

You can definitely leave that 4th stalk in there. Much less in costs. But once programmed, I dont think that 4th stalk will work anymore. If its not in the way, I would just leave it there. So you dont need to change out the assembly. Just the clockspring and then coding.

If bought together and new from Sonnen, I am pretty certain a dealer can code it for you.

Ok. Will do. So the clock spring is coded to the car. I thought that was the mechanism that canceled the turn signals when you rotated the steering wheel. I didn't know the electronics lived in there. I guess I will just have to live with the dead stalk. Sucks because I bought the little block off piece of plastic that covers the hole.

It may be possible to buy that switch assembly from ebay, and then use a new clockspring, but again, I am not 100% sure. I am 100% sure that a new clockspring with mult function will allow that multi function wheel to work. The 4th stalk may also work too.

Very interesting. Thank you for all your help. I was wondering how all those connections were made. I figured they were like the old horn buttons. Spring loaded carbon brushes on brass rings.
