DTCO 4.1b Update - What It Means For You

DTCO 4.1b Mandatory Software Update – What it means for you

The latest mandatory DTCO tachograph update is being rolled out by the manufacturer. For drivers and operators, what you should expect:

• Slightly longer calibration times at the workshop.

• Increased calibration costs when your tachograph needs a software upgrade.

Why the software update is worth it:

• Keeps your tachograph running smoothly with bug fixes and performance improvements.

• Reduces the risk of roadside delays during enforcement checks.

• Protects you from issues specifically and most importantly when the warranty period has ended.

The real win for drivers – the free VDO Fleet App

This update isn’t just about keeping your tachograph up to date, it unlocks daily benefits for drivers:

• Send manual entries directly to your DTCO remotely – no more fiddling with menus.

• Instantly see your driving and rest overview with VDO Counter data.

• Send working activities straight from your phone to the tachograph.

• Get live support to avoid working time infringements and stay compliant.

This app takes the guesswork out of managing driving and rest times, it is available to download for both Android & Apple devices.

Yes, the update may mean a little extra time and cost at the workshop, but the daily support from the VDO Fleet App makes a huge difference on the road — keeping you compliant, efficient, and in control.
