New windshield - now having driver support errors

[IMAY2023]

The car is in the shop. Technician told me it happens the calibration doesn’t go through, lately it seems to be more frequent he says.

Before leaving in the car I double checked the units in the car were aligned with the car. I could see first DTCs about missing speakers, wrong VIN number so after re-adding the original amplifier/speakers and then run restore to OEM , no more abnormal errors which can spook the trouble shooting.

Fingers crossed they get the radar calibrated.

Noted the calibration process is really stupid and requires the car to be driven on the roads , over 80 km/h with No car in front (50-60m) for at least 15 minutes on the straight well defined road (clear road markings). This is huge waste of time for a shop. Really surprised the don’t have an in shop calibration method !?

What kind of windshield you have? and calibration for what? 
Couple months ago I took my s60 2019 to the dealer for the sunroof. It was making noises on one side while closing. Lucky I noticed it just before the warranty ended. (48k miles). 
Anyway, the dealer changed the whole sunroof mechanism and for that, they removed the front  windshield , ceiling cover, and some other parts. 
They did the calibration as I was told, but they did not drive the car like that at all.  I picked up the car and never had issues with anything.
