The car came in from diagnostics all day, Mercedes says doesn't know what's wrong with it. Supposed to be called back next week for some solution.

I was driving a few weeks ago up a hill and the car made 2 large bangs and then lost power and rattled before regaining its composure. Brought it to my dealer and said the could not see any fault codes for misfiring. Any thoughts. My cars ecu has already been flashed before this happened.
