Lawyer as a last resort only.

Your car will record everything you do and any BMW dealership will be able to pull up the errors that your car is giving. Most cars now a days are just giant computers. Or like an modern airplane it is recorded like black box. Whatever you do will be there.

If you did or didn't over-rev it will be there and recorded. If your dealership can provide that proof, then you go from there. If they are refusing to give that proof, threaten them with the lawyer option and see what they do. If they still don't, then go with the lawyer.
