Hi Raz, it's the same problem I've been having with the steering angle sensor (I've made a couple of posts about it).
Had it in at the dealers, who thought it was the clock Spring...it wasn't. Then they said it's either the steering column control module or the wiring. Each costs around £500 but they can't give a refund if I choose one and it's wrong.....what an odd way to run a business. I'm not a f*uckin* game show. Pick one and hope it's right. Oh and they managed to damage my steering wheel.
I'd ask for you to have a look, Raz, but you're all the way down south. I'm up in Leeds.
