Even practical adjustments like recalibrating the distance coefficient after changing tire sizes are possible. For diesel vehicles, the pre-glow pictogram can be activated, and conversely, less critical pictograms like the “Please refill” warning at half-tank reserve can be deactivated if desired. Furthermore, warning pictograms for engine faults or battery control units can be selectively activated or deactivated based on user preference or specific vehicle configurations. Advanced features like “Curvmatic,” which provides visual and audible warnings for approaching curves too fast (when integrated with navigation), can also be enabled via xentry diagnosis das. For audio enthusiasts, the ability to change radio stations or frequencies directly from the steering wheel buttons can be activated, and even features like the “Fold-in Mirror” menu on older models (MY2005) can be brought to life. Finally, users can fine-tune the fuel consumption display for greater accuracy and deactivate various visual or audible warnings like “Remove Key,” “Switch Lights Off,” or “SOS Warning Message” for a less cluttered driving experience.
COMAND NTG1 System Tweaks with Xentry Diagnosis DAS
For Mercedes-Benz vehicles equipped with the COMAND NTG1 infotainment system, Xentry Diagnosis DAS provides a gateway to unlocking further functionalities. Similar to the instrument cluster, “Curvmatic” can be activated within the COMAND system. A popular modification is enabling DVD/TV video playback while in motion (for ECE COMAND APS NTG1 units), although local regulations should always be considered. The “Follow up time” for the automatic COMAND shut-off can be adjusted, and cosmetic enhancements like changing the boot-up logo to an AMG variant are also achievable. Retrofitting navigation or telephone modules? Xentry diagnosis das is essential for activating these features within the COMAND system. Software updates for the COMAND system can also be initiated through Xentry, ensuring your system is running the latest firmware.
Anti-Theft Alarm System Adjustments via Xentry Diagnosis DAS
The anti-theft alarm system is another area where Xentry Diagnosis DAS offers customization. If an alarm system is retrofitted, it needs to be activated via Xentry. Country-specific settings for the alarm can be configured, and the volume of both the alarm buzzer and the lock/unlock confirmation buzzer can be adjusted to personal preferences. The number of beeps for locking and unlocking, as well as specific beep patterns for situations like a door being incorrectly closed, are all customizable. For added convenience, the interior motion sensor can be deactivated when the sunroof closes automatically due to rain, preventing false alarms.
AIRmatic Suspension Calibration and Lowering with Xentry Diagnosis DAS
Vehicles equipped with AIRmatic suspension benefit significantly from Xentry Diagnosis DAS. The system allows for precise calibration of the suspension, particularly important if the car is sitting unevenly (“cricket stance”). Furthermore, for those seeking a sportier stance, Xentry diagnosis das can be used to lower the vehicle’s ride height, improving aesthetics and potentially handling.
Lighting System Enhancements Through Xentry Diagnosis DAS
Lighting customization is also accessible via Xentry Diagnosis DAS. Activating both rear fog lights for increased visibility in adverse conditions is a common modification. Cornering lights (on MY2004 and newer vehicles) can be enabled to improve nighttime visibility during turns. The timing for automatic low beam activation at dawn can be adjusted, and the brightness of footwell lights during driving (on Elegance and Avantgarde models) can be personalized.
Sunroof and Window Functionality Customization with Xentry Diagnosis DAS
Xentry Diagnosis DAS extends its reach to sunroof and window functionalities. The memory feature for the sunroof can be activated, allowing for favorite sunroof positions to be saved. The convenient “Sunroof closes automatically when it rains” feature can be enabled, and the “Close windows and sunroof” function via the infrared key adds another layer of convenience. Recalibrating the jam protection for the sunroof is also possible, ensuring smooth and safe operation.
Engine Management System Adjustments with Xentry Diagnosis DAS
While engine modifications should be approached with caution and expertise, Xentry Diagnosis DAS does offer certain engine-related adjustments. For vehicles with aftermarket sports catalytic converters, the deactivation of the standard catalytic converter and secondary lambda sensor monitoring can be performed (where applicable and legally permissible). On OM642 engines, the “Mass Average Adaptation Data” can be reset after air filter replacement. Throttle valve initialization after replacement is also a function within Xentry. For AMG models, the maximum speed limiter can be increased to 160 mph (where legally permissible and track use is intended).
