To service the Steptronic or not to service the Steptronic

[reblux5]

My wife just purchased an '07 X-5 3.0si. I have an '06 e90 330i with Steptronic.

Every time I ask the sales types about servicing the Steptronic, I get the standard response "It never needs service"!!??

Being an 'old school' driver, I don't believe that anything mechanical never needs service. The sales types about not needing service right up until the time it breaks.

If I plan to keep either of these cars beyond 100K, what would be a reasonable schedule for fluid change in the Steptronic?

Thanks, in advance...
