Yes, but I would suspect that the replacement may have already been done on your car since it is at 104k, maybe not though, hopefully BMW upgraded the material on replacemt part either way. You can remove the air filter and shine a flashlight in to the boot, you will see light if you have cracks. The codes will be thrown fairly quickly after a crack/tear develops, so this technique would essentially be used to diagnose the problem after the light comes on. Also, you can reach in after the engine cools and inspect the boot using touch.
