I recently upgraded to a heated steering wheel. So in order to do this, I had to get a new heated wheel, upgrade the SZL to support it, and then finally VO code the car adding in option 24, coding FEM_BODY, KOMBI, ICM, & HU_NBT.

Now when I start the car, I get the "cruise control malfunction" error. On top of that, none of the multifuction buttons, the horn, or the shift paddles work.

I've taken the SZL out a couple of times, but I can't find any noticeable damage to it, and the stalks still work. ISTA+ says its a faulty connection on the 6-pin connector inside the wheel, but for some reason, I feel like this a fault with programming.

Any thoughts on how to fix this??

Bump. Anyone have any leads on this??

So in case anyone else has this issue (I've seen some other posts on the board) I was able to solve the problem. Apparently when I installed my SZL, I assumed the steering wheel ring was centered...it was not. I think it was one turn away from centered. So when I would drive the car, any hard turns to the left pulled the wiring taught and shorted out a couple of the connections. 3 of the connections in one of the flat ribbons that controls the steering wheel buttons actually broke mid-ribbon. I was only able to find this testing continuities on the pins.

Long story short, I had to open up the SZL and re-solder a few connections. Works with no errors now.
