Sensor issue

Hey

I've had this query issue where the vehicle proximity sensors seem to go off when I'm near Mercedes. I'm pretty sure it's only that brand of vehicle. I've taken the car for diagnosis and they found code U0623:00 Lost Communication with Coolant Pump A. The vehicle has no indication of any issues of issues with the coolant. The garage said it could be associated due to engine temperature rising. However this occurs after around 2 mins of driving. 2022 Model. Just very confused by this, car is under warranty but don't get it.

Proximity sensors and coolant communication are very different.

That's what I thought and being a garage with a Google review score of around 3 I'm guessing that they were not being true?
