ive checked the plugs, airbag is fine no fault code from it only the hooter and buttons that dont work and I didnt remove
the steering when i carried out the job.

Not sure if there is a link bus converter on steering wheel or not, looks sort of like a can connector, converts line to can, if not the steering column module is faulty. What year is your car? Let me know and I will check for you

Check steering column pin 4,5,6
Check steering wheel plug same pin
4 - power
5 - ground
6 - data
See if any short circuit.

If have spare steering column and steering wheel, try swap.
