Nick beat me to it. Get a scan tool that can scan the readiness flags. The drive cycle is just ... driving the vehicle normally. Some of the better scan tools will let you monitor the readiness flags as you drive.

There should be no surprise that an aftermarket flash may screw with emissions readiness. BMW has been tougher to get around emissions readiness than most other makes since at least the E46 generation.
