Last year dealer told me I needed software update on my 2003 M3. To make a long story short I now have a brand new SMG transmission courtesy of BMW Canada. Approx $12,000 and a 2 year warrantee to top it off.
Ps if it is really need let BMW do it as they will be responsible should it not work properly and they will be on the hook to make it right.
It's really not a lot of money and you make a valid point - if anything happens, they will be on the hook for it.
