A repair should be possible with care depending on where it's broke.
Given what it does and the fact it moves little in service, I'd be inclined to do a full rewise job using sturdier ribbon cable of the type used in old computers for connecting hard disks and the like.
Dave, that is exactly how I broke my ribbon.. removing the switch clusters.. they are kind of snapped in to position, I think you bend a plastic tang and then pull them downwards / or upwards.. but they need a bit of force and when finally they come out, they can come out quick It should be obvious how the switch blocks are held in, when you have the wheel off..
I had a go at fixing mine but I am not to hot with soldering ... In the end I searched for breaking Xant on ebay and got someone to remove some and send them on to me.. think I paid 5-10£
I broke the ribbon on mine yesterday whilst changing my steering wheel for an activa leather one, Fixed it with a bit of careful soldering.
Also had to make an adaptor loom for the steering wheel control plug under the cowling, both cars are s2, airbag plug fitted ok but the radio control plug was different.

I am struggling with this problem as well. My radio buttons died when the local garage rewired my ignition switch after the aircon/rear screen contacts burned out. After a lot of hassle, Edwards of Billericay managed to find me the correct replacement, but still no joy. If anyone has any diagnostic procedures, I would be interested to hear of them/
