i have recently bought a bmw 528i 2011 . Its a beast and i love it so much. I have comfort keyless access package on my car installed. recently the button inside the trunk to close is not working.

Could some body please help with details of what went wrong.

 

Congrats on the new vehicle!
I would take it to an independent shop to have them diagnose it. Electrical problems can be a pain to figure out.
