To completely deny/void a warranty claim based on an exhaust flapper, BMW would need to prove that an open exhaust flapper specifically caused damage. What is more, (assuming you plug it back in when you goto the dealer) they would have to prove that YOU unplugged it and absolutely rule out a bad connection.
Voiding warranty based on tuner codes is a totally different story.

I said an aftermarket exhaust voided their warranty. Threw a code for an engine problem. Not talking about just the flapper as you weren't in your claim an aftermarket exhaust wouldn't void the warranty.
