Two weeks ago, my W206 (C180, built in the summer of 2023) was in a rear-end collision due to tailgating in a small town in Greece. The driver that caused the accident was following way to close to me for a couple of minutes and when traffic came to a halt, she didn't brake at all. The collision was intense and my car moved forward at least half a meter despite being braked. I was lucky that I had enough space from the car in front of me and that her car was very low so she collided with my rear bumper only, which was cracked along with the plastic parts underneath. Now, I am waiting for the new bumper and the plastic parts to arrive, the latter from Germany. At the dealership, they told me that there are no error messages, that they will re-calibrate my sensors, and will check for further damage after removing the bumper.

My question is if there is something to check in particular in addition to the above.

Any suggestions and advice would be appreciated.
