During the last year, I replaced already 3 boards, waiting for the 4th OEM to go South, from Hyperlights - Russia.
Absolutely no issues with comfort access or any other functions on the car.

On another note:
I change the garage door opener with a new generation Lift Master. I didn't like the light output, so I changed the bulbs with LED bulbs. Nice bright light, but: both BMW's failed to open/close the garage door. Did some research, and Lift Master has only a few LED light bulbs that are compatible with the garage door opener because they say it WILL interfere with the signal. Weird, but it happened to mine. So maybe if one switches the regular tail lights with some LED lights from Chinaland, those could interfere with the signal of the comfort access. After all these are diodes.
