did you do the install of the clock spring yourself, or you paid someone do it for you? could it be that a ribbon cable is pinched/jammed/bent or whatever?

Not sure about the rear wiper as I didn't try mine during the time. I had the airbag & seatbelt lights, radio was intermittently working, no power steering, seat heaters didn't work, visor mirror lights didn't work and steering wheel buttons didn't work to name a few. Changed the ignition switch myself and everything returned to normal.

I changed the clock spring my self

you might need to retrace your steps with the clock spring to make sure that no wires are nicked or pinched - an alternative electrical path can create unexpected results in these electrical circuits

It sounds like at least some of your problems are due to the recent work you performed or had done at your local shop. You just replace the horns...and they don't work. You just took apart the steering column, and the airbag light is on and the rear wiper and steering wheel controls won't work. Are you sure you're not out of your depth working on this car?

X5's can be VERY tricky cars to work on, especially if you're new to BMWs. Anything electrical can be diabolically difficult to work on, and many jobs involving electrical components are impossible to diagnose or put right without a dealer level scan tool.

There are a LOT of jobs a non-technician owner can do, especially with the help of the tutorials found on this site, TIS, and Bentley manual. But it's certainly possible to foul things up if you're not careful.

All this random stuff not working, I now have a feeling its is the ignition switch as well.

But in all honesty, a good diagnostic computer is worth it's weight in gold. Seriously.

Did you disconnect the battery before removing the airbag/steering wheel or did you leave it on?
