Fault Code 4F85 is "Passive". It CAN be set by low transmission fluid. Any shop that can put car on lift with engine running can check fluid level. See the link below for BMW Fault Code Lookup Fault Info sheet for 4F85:

I would simply call several Transmission Shops & ask them what their charge would be for Fluid Level Check on ZF 6HP19 AT. Make sure they have correct spec. for Fluid. If any question about procedure (Engine must be running as final 2 Qt. of fluid are added), or proper fluid, please post back. If you have NOT had the fluid or Filter changed in last 50,000 miles, NOW would be good time for that.
