Advanced fault diagnosis, control-unit programming, software updates, ADAS calibration and retrofitting for Mercedes-Benz, Mercedes-AMG and Mercedes-Maybach models in Dubai.
WHAT IS YOUR MERCEDES TRYING TO TELL YOU?
WARNING LIGHTS
Dashboard warnings may be caused by a sensor, control unit, wiring fault, low voltage or communication problem. Reading The cause must still be tested properly.
BATTERY DRAIN
If the battery keeps going flat, there may be a weak battery, charging problem or an electrical component that continues using power after the vehicle is switched off.
STARTING PROBLEMS
Slow starting, intermittent starting or a vehicle that does not start may be related to the battery, starter system, wiring, control units or vehicle communication.
INFOTAINMENT AND DISPLAY FAULTS
Frozen screens, restarting displays, sound-system problems and connectivity faults may require software diagnosis, coding or control-unit inspection.
SENSOR AND CAMERA WARNINGS
Parking sensors, cameras, radar systems and driver-assistance features may develop faults after an accident, windscreen replacement, suspension repair or wheel alignment.
ELECTRICAL FEATURES
NOT WORKING
Windows, seats, mirrors, lights, soft-close doors, climate controls and other electrical functions can fail because of switches, motors, wiring, programming or control-unit faults.
SOFTWARE AND COMMUNICATION FAULTS
Modern Mercedes-Benz vehicles contain many control units that communicate with each other. One unit, wiring problem or voltage issue can create several warning messages at the same time.

HOW OFJ DIAGNOSES YOUR MERCEDES-BENZ
CUSTOMER CONCERN 
We begin by understanding the warning message, symptom or electrical feature that is not working.
XENTRY DIAGNOSTIC
The vehicle is connected to Mercedes-Benz XENTRY Diagnosis to read fault codes, control-unit information and live vehicle data.
TECHNICAL TESTING
Our technicians test the affected system using model-specific information, electrical measurements and component checks.
ROOT-CAUSE REPORT
The customer is informed about the actual cause of the problem, the recommended repair and the estimated cost before additional work begins.
REPAIR, PROGRAMMING
After approval, the required repair, coding, programming or software update is completed. The system is then tested again to confirm correct operation.
MERCEDES-BENZ DIAGNOSTIC TECHNOLOGY AT OFJ
Some Mercedes-Benz faults cannot be repaired by replacing a part alone. A new or existing control unit may also require coding, programming or software configuration so that it can communicate correctly with the vehicle.
XENTRY DIAGNOSIS
Used to read and clear fault codes, analyse live vehicle data, activate components, carry out service functions and communicate with Mercedes-Benz control units.
XENTRY WIS
Provides model-specific repair procedures, wiring information, component locations, tightening specifications and removal or installation instructions.
XENTRY TIPS
Helps technicians research known Mercedes-Benz complaints, fault patterns and technical repair information.
XENTRY PARTS INFORMATION
Used to identify the correct Mercedes-Benz components and part numbers using vehicle-specific information.
Some Mercedes-Benz faults cannot be repaired by replacing a part alone. A new or existing control unit may also require coding, programming or software configuration so that it can communicate correctly with the vehicle.
CONTROL-UNIT CODING AND PROGRAMMING
Configuration of supported Mercedes-Benz control units after diagnosis, repair or component replacement.
SCN CODING
Mercedes-Benz software configuration used to match supported control units with the correct vehicle specifications.
SOFTWARE UPDATES
Updating supported vehicle systems when newer software is required to correct operation, improve compatibility or complete an approved repair procedure.
CONTROL-UNIT ADAPTATION
Teaching or adapting supported components and control units after replacement or repair.
CAMERA & RADAR CALIBRATION
MERCEDES-BENZ ADAS CALIBRATION
Mercedes-Benz driver-assistance systems rely on correctly aligned cameras and radar sensors. After windscreen replacement, accident repair, suspension work or wheel alignment, OFJ recalibrates supported ADAS systems so the vehicle can read the road accurately again.

Mercedes FAQs
QUESTIONS.
ANSWERED.
XENTRY is Mercedes-Benz diagnostic software used to communicate with the vehicle’s control units. It helps technicians read fault codes, view live data, activate components and carry out supported diagnostic functions.
Yes. OFJ can diagnose dashboard warning messages and electrical faults using XENTRY and supporting testing equipment. The fault code is only the starting point; the system is tested to find the actual cause.
No. Clearing a code without repairing the cause may allow the warning to return. OFJ checks the affected system and recommends the correct repair before completing a final test.
Yes. OFJ can carry out supported control-unit coding, programming, SCN coding and software updates. Availability depends on the vehicle model, control unit and software compatibility.
Yes. OFJ has in-house ADAS calibration equipment for supported Mercedes-Benz camera and radar systems.
Calibration may be required after windscreen replacement, accident repair, camera or radar replacement, suspension work, wheel alignment, ride-height changes, bumper or grille removal, or when a driver-assistance warning appears.
Yes. OFJ can carry out selected regional configuration changes for supported imported Mercedes-Benz vehicles, depending on model, hardware, software compatibility and legal requirements.
No. Some features need extra hardware, wiring, sensors or compatible control units. OFJ checks compatibility before confirming any retrofit or feature activation.
