Mercedes-Benz XENTRY Online Coding & Programming
Mercedes-Benz SCN coding, programming and software updates with XENTRY online: engine, transmission, SAM, cluster, airbag and more. Mobile across Melbourne.
Most replacement control units on a Mercedes-Benz will not work until they are coded online to the vehicle. We use XENTRY online, the manufacturer's own diagnostic and programming system, with a live connection to Mercedes-Benz. New and used control units are SCN coded, updated and initialised to dealer standard, at your workshop or ours, without the dealership wait.
What is SCN coding?
SCN (software calibration number) coding matches a control unit's software and settings to the vehicle's VIN and factory specification, which Mercedes-Benz keeps on record. When a control unit is replaced, the new one has to be programmed and coded online against that record. Until it is, the car can log faults, run in limp mode or refuse to start. Offline tools can read faults and change some settings, but SCN coding and most software downloads need XENTRY online.
Mercedes-Benz control units we program and code
- Engine control units: replacement units programmed and SCN coded, software updated, or the original unit's data cloned onto a replacement
- Transmission control units and conductor plates on 7G-TRONIC and 9G-TRONIC gearboxes, followed by the adaptations the gearbox needs to shift properly
- Instrument clusters: replacement units coded to the vehicle. We do not alter odometer readings.
- Front and rear SAM (signal acquisition) modules and other body control modules after water damage or failure
- Airbag (SRS) control units, including units that have stored crash data
- ESP and ABS control units: replaced and coded, followed by steering angle and sensor calibrations
- Comfort, door, seat, lighting, parking and camera modules
- Variant coding when factory parts are fitted or swapped, where the vehicle supports it
Software updates and initialisations
Mercedes-Benz releases software updates that fix known faults, from rough shifting to battery drain and warning lights that come and go. We check every control unit for updates through XENTRY online and install the ones that apply. After repairs we carry out the initialisations and adaptations the job needs: steering angle sensor, window and sunroof normalisation, seats, transmission adaptations and more. See ECU reflashing and software updates.
Warning lights and fault finding
Check engine light, airbag light, ESP or ABS warning, transmission in limp mode, or a long list of faults after a repair? Every Mercedes job starts with a full scan of every control unit. We find the cause before anything is replaced, so you are not paying for parts the car did not need.
Models we work on
Mercedes-Benz passenger cars, SUVs and vans, including A-Class, B-Class, C-Class, E-Class, S-Class, CLA, CLS, GLA, GLB, GLC, GLE (and the earlier ML), GLS, AMG models, EQ electric models, Sprinter and Vito.
For workshops, panel shops and dealers
Independent workshops, panel shops, wreckers and used car dealers send us the Mercedes-Benz jobs that need online coding. We come to your workshop anywhere in Melbourne, or you bring the vehicle to ours in Reservoir. Every job finishes with a full scan report, so you can hand the car back with confidence. Selected modules can be posted to us from anywhere in Australia for cloning or programming on the bench. Not every module can be done this way, so send us the part number and we will confirm before you post anything.
Other makes
We also program and code Mercedes-Benz, BMW, Audi, Volkswagen, Skoda, Ford, Mazda, Toyota, Land Rover, Kia, Hyundai, Mitsubishi, Nissan, Honda and Renault and many more with genuine manufacturer software. See all our module programming and coding services.
Mercedes-Benz XENTRY Online Coding & Programming: common questions
Do I need to go to a Mercedes-Benz dealer for coding and programming?
No. With XENTRY online we can program, SCN code and update Mercedes-Benz control units to the same standard as a dealer, usually much sooner. We can come to your home or workshop across Melbourne, or you can bring the car to our Reservoir workshop.
What is Mercedes SCN coding?
SCN (software calibration number) coding matches a control unit's software and settings to the vehicle's VIN and factory specification held by Mercedes-Benz. A replacement control unit needs SCN coding online before it works properly in the car.
Can you code a used or second-hand Mercedes-Benz control unit?
Many used control units can be reprogrammed and coded to a different vehicle. Some cannot be reused, or need the original unit's data cloned onto them instead. Send us the part number before you buy and we will tell you which applies.
Do you work on Sprinter and Vito vans?
Yes. We program and code Mercedes-Benz vans as well as passenger cars and SUVs, including fleet vehicles. We can come to your depot or workshop to keep downtime short.
How much does Mercedes-Benz coding cost?
It depends on the control unit and what the job needs, such as software downloads, coding and adaptations. Call us or send the details through the contact form and we will give you a price before any work starts.
Do you come to my workshop?
Yes. We are a mobile service across Melbourne and regularly code Mercedes-Benz vehicles at independent workshops and panel shops. You can also bring the vehicle to our workshop at 39 Radford Road, Reservoir.
