They broke my adas camera unit. So couldn’t re-calibrate it when they fitted the new windscreen at Derby (30 miles away) and my EX30 is now finally at Volvo. Indeed it does need a whole new unit. Which is on backorder and who knows when the part will become available, been on BO since the beginning of April. Which is when I had the windscreen originally replaced. What an ordeal I can tell you. but at least I have a Mach e Mustang / premium 91kwh as a replacement for which some seemed to dismiss my reasons for requiring an EV as a replacement and that I would.
I changed my appointment time and date online to one more suitable as the one that I had booked clashed as a more important meeting had to happen on that day. So no reason you cannot change it. If the crack is into the wiper area. I’d personally get it replaced asap.
