Steering Rack

[PapX5]

So I brought my X in few days ago to get the rear brakes done and I off-handedly mentioned that I was hearing a clicking noise now and then when I was turning the vehicle in tight spaces...parking for example. They checked it out and indeed there was a problem apparently with the steering rack and they had to replace a few things:

Part numbers...
32-13-6-761-823 X5 EXCH. 32K3
32-13-6-761-823 CORE RETURN
32-41-1-093-596 SEALING R D8
83-22-9-407-858 GEARBOX 0 BULK
32-41-1-093-597 E32 GASKE D8

My question is was this a serious problem? If I hadn't noticed anything or mentioned to the dealer could this have become a larger problem? They seemed to think it was a big problem and it took them 3 days to fix

I must say though that the steering is tighter than ever before...feels kinda starnge actually!
