Even if you are legally in the right, legal fees to go up against BMW will outweigh the cost of the repairs. MM might help if they want to deny engine warranty because you have an aftermarket stereo amp, but not for a tune or a downpipe that directly alters the system in question.
Agree with Maynard. As a lawyer who has actually read the MM Act I believe he is correct. This old wife's tale still has legs, however.
