The sensor itself seemed ok in my case, but the plastic supports, from cover and mount piece were shattered. So they required replacing. I used Carista to reset the fault codes and it has worked well (ish) since then. I do appear to have another
problem related to my front lights that will disable the front assist after around a few minutes of driving though... haven’t bothered to get round to fixing that yet.
Depending on how much space there is in the grille to fiddle, it might be worth checking to see whether the connector at the bottom is dislodged too.
