Repair to Steering Column on 2006 BMW 330i

In December 2010 I brought my 2006 BMW with 20,114 miles to a BMW dealership for a fault light pertaining to my steering wheel. I was not experiencing any problems with the steering wheel (turning the wheel, starting the car, locking of the wheel, etc). However, I did authorized the work after BMW informed me that it was a safety related issue. After consulting with my local mechanic it was evident that unnecessary repairs were performed on my vehicle. After contacting BMW Headquarters in Germany and North America I received a full refund from the dealer. Within 3 months additional repairs to parts of the steering column (firewall boot and clock spring) were necessary and performed by another BMW dealership totaling $678.09.
How likely is it that the steering column would have to be replaced on a BMW with 20,114. Also could the initial replacement of the steering column disturbed the fire wall boot and clock spring when the new column was placed in the steering wheel.

not likely. however, proving or disproving this would involve expert witnesses and a lawyer. when dealing with
any dealership, you are considered guilty and they are innocent until you prove otherwise. this is precisely why
80% of all customers leave the dealership after their cars
warranty expires. the 20% that remain with the dealership
are somehow convinced that they will always do the right thing. instead, it was your local BMW tech (you incorrectly
called him a mechanic) that did the right thing. the mileage is irrelevant, your car is out of warranty and you
are a service orphan. save you money and become buddies with your local BMW tech
Thanks and your right. BMW aid wear and tear caused the problem. Wear and tear after 20,000 miles. Are you a mechanic/Technician?
No...I'm service manager at a large independent German specialty shop. I have 5 technicians and no mechanics :)
