2020 Mercedes-Benz E-Class — windshield replaced — does camera calibration matter? — anyone dealt with this recently?

2020 Mercedes-Benz E-Class E450, about 113,500 miles. A new windshield is installed and there is no dash warning, but the shop recommends camera calibration. If the manufacturer procedure calls for it, would you do it even when lane-assist functions appear normal?

I'd keep this practical. Verify the cheap/easy branch on the 2020 Mercedes-Benz E-Class before a big repair or a big spend. Then you'll know the next fork. Write the result down so the next test isn't a repeat of the last one. I'll update if anything new shows up.

Write down what you already tried. A second data point from another 2020 Mercedes-Benz E-Class owner helps more than a generic diagnosis. I'd do that before spending real money. This is from a 2020 Mercedes-Benz E-Class in Columbus with 113,500 miles. If they can't show the line item, I assume it's hiding. This is the version I'd tell a friend.

Owner notes beat generic advice here. On the 2020 Mercedes-Benz E-Class in Columbus, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “benz e-class — windshield replaced — does,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. Wrote this up on my lunch break.

Don't overfit one forum story to your car. If it still isn't clear on the 2020 Mercedes-Benz E-Class, a specialist hour can be cheaper than another round of parts. That's where I'd start. Was this after sitting overnight? That's coming from doing this as an owner, not a shop. I'm in no rush to be a hero on it.

Thanks — that narrowed it. I'm going to try the simpler check on the 2020 Mercedes-Benz E-Class first. I'm keeping receipts and dates in one folder.

I'd rather look cautious in this thread than stuck later.
