Mercedes Sprinter and Metris Diagnostic Scanners and Adapters

Written by the YOUCANIC technicians in Towson, Maryland, from the UCAN-II Pro coverage database and our own shop work. Updated October 24, 2026.

A Sprinter earns its keep on the road, and the parts store code reader that only sees the engine cannot clear a DPF warning, tell you why the van went into limp mode, or reset the service counter when the oil is done. A current Sprinter 910 carries sixty control units. The tools below are what we use in our own shop in Maryland to reach every module on a Sprinter, Vito or Metris, run the adaptations the dealer charges an hour of labor for, and get the van back to work. The coverage database behind the UCAN-II Pro lists the Sprinter 901 to 905 family, the 906, 907, 909 and 910, the Vito and Viano 639, the Vito, Metris and V Class 447 and 448, the Citan and the X Class. Pick by what you need to do, then read the connector note.

Which Scanner Do I Need For A Sprinter?

CHECK ENGINE LIGHT ONLY

UCAN-GO

Reads and clears engine codes from your phone and gives you a live gauge dashboard. It does not see the ESP, SRS, transmission, level control or body modules, and it cannot regenerate a DPF or adjust an injector. Right if the only light you care about is the engine one.

EVERY MODULE, EVERY SERVICE FUNCTION

UCAN-II Pro, new or open box

Full system, bidirectional, lifetime free updates. Reads and clears every control unit and runs the Sprinter adaptations: DPF regeneration, injector quantity adjustment and classification, zero quantity calibration, yaw rate sensor calibration, rear axle level calibration, maintenance interval reset, variant coding, rain and light sensor and actuator motor teach in. The tool to own if you keep a Sprinter working.

ONE JOB THIS MONTH

Rent the UCAN-II Pro for a week

Same scanner, shipped both ways free, with a refundable deposit that comes back when the scanner does. For the one DPF regeneration, injector adjustment or limp mode diagnosis you need done once.

What The UCAN-II Pro Does On A Sprinter

• ✓ Reads and clears codes in every control unit: 60 modules on a Sprinter 910, from the OM651 and OM642 engine electronics and the VGS transmission control to the ESP, SRS, cluster, Collision Prevention Assist, Parktronic and steering column module; 47 on a Vito or Viano 639
• ✓ Regeneration of the Diesel Particulate Filter, Regeneration of the DPF when driving, Teach-in the used DPF and Initialization of system Diesel Particulate Filter after a new filter
• ✓ Adjustment of the injector injection quantities, Injector classification and Zero quantity calibration after injector work on the CDI engines
• ✓ Initialization of the Air filter, Throttle valve positioner, Air intake and turbocharging and Common Rail systems after component replacement
• ✓ Calibration of the B24/15 yaw rate, lateral and longitudinal acceleration sensor, Trailer stabilization, Hill descent and Start-off assist settings on the ESP, with active tests on the ESP, ESP9 and the RDK tire pressure monitor
• ✓ Level calibration on the ENR rear axle level control, Calibrate the control module LWR on the headlamp range adjustment, Learn gears and Learn clutch on the Sprintshift transmission
• ✓ Reset of maintenance interval display in the instrument cluster (the oil reset category on the 447 Metris and the Sprinter), Tire size and Maximum vehicle speed limit
• ✓ Body: Teach-in the Rain/Light Sensor and the Battery-operated horn, Teach-in the actuator motors on the climate control, Normalize the sunroof, Reset alarm sources, Central Locking customer-specific settings and Variant coding
• ✓ Live data with graphing and recording, plus TPMS: Write the wheel electronics ID number on the RDK and the U360 replacement sensor programmed from the tablet

Service Functions By Job On A Sprinter

On the tablet you pick the control unit, then the function category, then the routine. The Sprinter database uses the Mercedes categories: Control Unit Adaptations, Special Functions, Active Test, Oil Reset and Initial Startup. These are the routines it lists, grouped by the job you are doing, named as they appear on the tablet. Coverage varies by van and year, so check yours before you order.

What The Scanner Sees On A Sprinter

Two vans pulled from the coverage database, with the control units the UCAN-II Pro lists on each. Every unit gets fault codes, live data and, where the database shows it, active tests and adaptations.

The 639 is the European Vito and Viano, the same family as the Metris 447 sold here, which the database lists under its own class with the IC447 cluster and its oil reset.

Symptom, Then The Routine That Fixes It

• DPF warning or limp mode on a van that idles a lot or does short runs: Regeneration of the Diesel Particulate Filter once the codes behind it are cleared; Teach-in the used DPF or Initialization of system Diesel Particulate Filter after a new filter.
• Rough idle, smoke or a misfire count after new injectors: Adjustment of the injector injection quantities with the new injector codes, then Injector classification and Zero quantity calibration.
• ESP light and a yaw rate or acceleration sensor code after a sensor or alignment job: Calibration of the component B24/15 (Yaw rate, lateral and longitudinal acceleration sensor) in the ESP.
• Rear of the van sits low or uneven on a model with rear axle level control: Level calibration in the ENR after the ride height is set.
• Service reminder still on after the oil change: Reset of maintenance interval display in the instrument cluster, the Oil Reset category on the tablet.
• Tire pressure light after new sensors or wheels: Write the wheel electronics ID number on the RDK; or program the U360 sensor to the old ID first.

Frequently Asked Questions

Does my 2016 Sprinter 2500 (906) need an adapter?

No. The 906 plugs straight into the 16 pin port under the dash, and the UCAN-II Pro reaches the engine electronics, transmission, ESP, SRS, cluster and body modules without the 38 pin adapter that the 1990s Mercedes cars use.

I have a 2020 Sprinter 907. Will it work?

The 907 is in the coverage database. Check your van on the coverage checker for the module and function you need, or email support@youcanic.com with the VIN and we will tell you what the scanner reaches on it and whether any adapter is needed before you buy.

Will it regenerate the DPF on my OM651 or OM642 Sprinter?

Yes. The database lists Regeneration of the Diesel Particulate Filter and Regeneration of the DPF when driving on the CDI engine electronics, plus the Teach-in and Initialization routines for a new filter. Clear the codes that blocked the regeneration first, and run it with the engine at temperature and a full tank of fuel. The DPF guide walks through it.

Does it do SCN coding or program keys on a Sprinter?

No. Those need Mercedes server access through Xentry. The UCAN-II Pro does diagnosis, live data, active tests, local variant coding and the adaptations listed above.

Can I rent it for one job?

Yes. The rental is a one week rental plus a refundable deposit that comes back when the scanner does, shipped free both ways. Most Sprinter renters want a DPF regeneration, an injector adjustment or a limp mode diagnosed.

How do I know my exact van and function are covered?

Use the coverage checker by van and module, or call 1-888-959-4265, Monday to Friday 9 AM to 4 PM Eastern, and a technician will tell you plainly. If it does not do what you need, we will say so. Every scanner also comes with 31 day returns, no questions asked.
