Some real case studies in the book

Inside this guide, you won’t just find theory—you’ll discover real-world case studies that show exactly how to unlock hidden features and perform specialized coding on Mercedes-Benz vehicles. Each case includes the problem or request, the ECU involved, and the step-by-step coding path, with screenshots captured directly from DTS Monaco.

These practical examples ensure that you can immediately apply the knowledge in your workshop, whether you’re customizing customer vehicles or solving tricky issues during diagnostics. Let’s explore some instructions from the book:

1. Start/Stop Function – Remember Last Choice Keep Turned Off (MED40)

One of the most common requests from Mercedes owners is disabling the automatic Start/Stop function. In this case, we show how to configure the MED40 ECU so that the system remembers the driver’s last choice and stays off after restarting the vehicle.

2. AdBlue Workshop Menu (W212)

For technicians working with the W212 series, the AdBlue workshop menu is a critical tool. This case study demonstrates how to activate it, allowing you to monitor AdBlue levels and carry out adjustments during servicing or when troubleshooting SCR-related faults.

3. ESP Off Menu (W166)

Electronic Stability Program (ESP) is a vital safety system, but in some situations—such as testing or special driving conditions—you may need to enable the ESP Off option. Here we provide detailed steps to unlock this hidden menu on W166 models.

4. Limited Speed Menu (W166)

The Limited Speed menu exists in many W166 vehicles but is often disabled by default. This case study explains how to activate or deactivate the function, giving the driver more direct control over speed management.

5. Change Language on HU6

For imported vehicles or customers requiring different languages, it’s often necessary to reconfigure the infotainment system. Here we show you how to change the display language on HU6 units, complete with screenshots of the actual coding process.
