Don't do it unless you've experience some problem.

CAS, It depends on your ride. If you have Steptronic (auto), I'd say get it upgraded to 17.01. My late 2004 built 2005 improved significantly with 16.3 and 17.01 is supposed to fix the "slam" problem, so I am getting it next week. There is another thread on this problem you should see. If you have manual or SMG, I am not so sure it is worth the effort.
