Did you register the new battery? Otherwise DME will still think you have the old battery and will disable features such as keyless entry etc.

Check the module inside trunk next. These tend to get moisture and go bad. I replaced mine in my E88 a few months back.

The E91s are notorious for broken wiring at the hatch hinge. Something fun to look for!
