How to Activate Benz Temperature Mode with DTS Monaco?

In this guide, we will walk you through the process of activating the temperature display mode on a Mercedes using the DTS Monaco software and the VXDiag VCX SE Benz diagnostic tool

running Xentry 2025.06. This tutorial will also cover how to switch temperature units from Fahrenheit to Celsius and customize other display settings.

 

Tools Required

1. VXDiag VCX SE Benz or VCX Plus Benz

2. DTS Monaco Software – Used for coding and diagnostics.

3. Battery Charger (35A recommended) – Essential for long coding sessions to prevent battery drain.

 

The Issue: Temperature Display

On many Mercedes models, the temperature of the coolant isn’t displayed numerically (e.g., 90°C, 130°C) in the service or progressive menus. Additionally, the default temperature unit may be set to Fahrenheit instead of Celsius. Today, we’ll show you how to enable numerical temperature display and switch Fahrenheit to Celsius using the VCX SE Benz scanner and Monaco software. We’ll also adjust other settings, such as fuel consumption units (liters per 100 km, gallons, etc.) and pressure units (bar).

Step-by-Step Guide to Coding

Here’s how to activate the temperature display and customize units:

1.Connect the Scanner

1. • Use the new VXDiag VCX SE scanner, connecting it to your vehicle via Wi-Fi.
   • Ensure the ignition is set to the second position.
   • Plug in your battery charger to maintain power.

2.Launch DTS Monaco Software

• • Open Monaco and select your project for the Mercedes model (in this case, a 213 model).
  • If you encounter an error, double-check that the scanner is properly connected. The software should indicate that the VCX is “available.”

3. Configure Settings

1. • Navigate to the Variant coding menu for the 213 model- ECU-IC213- 007 Country Coding Write.
     
   • Adjust the following:
     • Temperature Units: Change from Fahrenheit to Celsius.
     • Cold Scale Menu: Enable numerical temperature display for the instrument cluster.
     • Other Units: Set fuel consumption (liters per 100 km), distance (kilometers or miles), and pressure (bar) as desired.
   • Once all settings are adjusted, click “Coding” to apply the changes.

4. Verify the Changes

• • Go to the “Diagnosis” section in DTS Monaco and connect to the IC (Instrument Cluster) for the 213 model.
  • Perform an “ECU Reset” to ensure the new settings take effect.

• • Check the service menu, AMG menu, or sport menu on the vehicle’s display. You should now see numerical temperature readings (e.g., 50°C, 90°C, 130°C) and Celsius instead of Fahrenheit.

Results

After coding, the temperature is now displayed numerically in the service, AMG, and sport menus. The units have successfully switched to Celsius, and other settings like fuel consumption and pressure are updated as configured. The VXDiag VCX SE Benz performed flawlessly during this process, proving to be a reliable tool for advanced diagnostics and coding.

VXDIAG VCX SE and VCX VX800 Benz Comparison

What’s the difference between VXDIAG VCX SE Benz and VXDIAG VCX VX800 Mercedes diagnostic scanner?

VXDIAG VCX SE Benz

VXDIAG VCX VX800 Benz

First of all, they are not a new version and an old version—they are simply products from different distributors.

• VCX VX800 is an e-commerce product sold online.

• VCX SE is the global version. It is available both offline and online dealers.

The hardware and main board are exactly the same—the only differences are the device labels and packaging.

Their functionality is identical, and both support adding authorization software for additional vehicle models.

So it is a rumor if someone says the newer VCX VX800 offers improved functionality.

VXDIAG ODIS 24.3.2 Asks for GRP Login Info?

Problem:

One of our customers has managed to set up ODIS Service 24.3.2 software with VXDIAG VCX SE 6154 interface. Software reads VIN, but when processing the diagnostic, it asks to input user name and password. Where to get the login info?

Here is the clue:

Group Retail Portal (GRP) is a centralized access point and authentication process for ODIS Service. It is replacing the current ODIS logon process since version 23.

We don’t provide the GRP login user name and password.

Better use VXDIAG ODIS software. It is cracked without login info. The latest version goes to 24.1.1.

VXDIAG HDS 3.105 Not Connect to Civic 2008 Solution

 

Problem Description

A user encountered an issue where the VXDIAG VCX SE Honda device and HDS 3.105.012 software could read vehicle information (e.g., VIN) but failed to communicate with modules or perform diagnostics on a 2008 Honda Civic. The problem persisted even after trying a different computer (Windows 10).

 

Solution

After remote diagnostics by VXDIAG engineers, it was determined that the issue was related to software permissions. The HDS software required administrative privileges to function correctly.

Run HDS Software as Administrator. 

Select “VXDIAG” as the diagnostic device in connection settings.

How to Solve BMW E-Sys “Failed to get CAFs for SWE” Error?

 

Problem:

Unable to code the ECU via E-Sys, the error “Failed to get CAFs for SWE” appears when trying to code.

Mini F55 Cooper S 2018, faulty ASD (Active Sound Design) ECU replaced with another used one.
ISTA shows an error that the ASD ECU is not coded.
E-Sys shows that ASD does not have CAFD.

There is no CAFD in the ASD ECU, but there should be.

In E-Sys, select ASD [3f] and click “Detect CAF for SWE”.

Error message:
Failed to get CAFs for SWE “swfl_…”
KIS error: The technical unit … could not be found in the KIS knowledge base.

Error Failed to get CAFs for SWE when clicking Detect CAF for SWE.

 

It is not possible to code the ECU.

Create an SVT Target in E-Sys, if possible with an I-Step (target) as close as possible to the I-Step (current) or higher than the I-Step of the used unit (see I-Step current in VCM).

It is clear that SWFL_000021D4… is suggested to be deleted from the ASD ECU, and SWFL_000029ED… loaded instead, and CAFD_00000F9B… added.

In SVT Target for ASD ECU it is suggested to load SWFL_000029ED… instead of SWFL_000021D4… and add CAFD.

 

In this case, the error “Failed to get CAFs for SWE” appears because E-Sys cannot find CAFD for SWFL_000021D4… and the current FA configuration, because for the current configuration, the ECU must have a different SWFL (there must be SWFL_000029ED… instead of SWFL_000021D4…).

To flash another SWFL into the ECU you need: ENET/ICOM/VXDIAG VCX SE, E-Sys (without launcher), PSdZData full, voltage source for programming.

Create a TAL and program the ASD to replace the SWFL and add CAFD to it (be sure to connect a voltage source to the machine to maintain voltage of at least 12.6 volts, at least for the duration of programming).

After programming, in the ASD module,  SWFL_000021D4… disappeared and SWFL_000029ED… and CAFD_00000F9B…appeared.

ASD was coded after SWFL change, CAFD appeared.

The ASD ECU is programmed, coded, works, no errors.
