Keep in mind that the MP LSD works in tandem with the brake-based E-diff and DSC which has a predetermined algorithm for the 240i's gear ratio.

Using a different final drive without altering the transmission's ECU set mapping might possible throw off the vehicle stability control and/or speedometer.

If you were working with a manual transmission, I would say you're fine but an auto tranny operation is tied directly to the ECU's logic. The fact that you're getting an MIL is telling the computer that something is not plausibility, which might have consequences you're not anticipating.

I hope it works out for you but I would do some solid research before I leave it as is. Good luck and keep us updated.
