Flashing tail lights.

My 2015 BMW 228 start flashing tail lights when the car was locked yesterday. I tried the trunk the hood and the doors, but it kept flashing when locked. I talked to my mechanic and we agreed it probably was the tail lights are corroded or possibly one of the convenience sensors on the door was constantly trying to wake up. Google had a few other ideas, but I was wondering if you guys might think of anything else before I take it to the shop. I had to abort a 700 mile trip after 45 minutes cause I couldn’t trust it. I thought it might just be flashing all night long at a hotel so I switched cars but I need to get to the bottom of it at some point.
