Applied by Mercedes-Benz during production, seems to refer to the tachograph by serial number but doesn’t have an expiry date?
Is there a need for an expiry date?
In Transport’s Friend the example shown does not have one.

All details appear to be there, including date of calibration. No problem I can see.

Looks to me to be the initial calibration sticker done at Mercedes. Its got all the right info on it so your next one should be 2 year from the date shown, ie 4.7.2026

Thanks for the feedback, as I was unsure on the mandatory content.
