it was going to happen to me. My 330Ci retrofit steering rack has failed.

Yup, less than one year and less than 3,000 miles and the POS is making noise and it's leaking.
If it isn't broken, don't' fix it. I guess that goes both ways, BMW AG for ever missing with the steering in the first place (making it lighter in 2001)

and for me actually going through with having the retrofit performed. I knew something like this was bound to happen.
