Diesel injectors atomize fuel with precision, and worn or leaking injectors cause rough idle, misfire, smoke, and hard starts. We test injector return and correction values, replace the failed units with genuine parts, and code them to the ECM so your Sprinter runs smooth and clean again.
What this service includes
- Read injector correction and return flow data with Xentry
- Identify the leaking or failed injectors
- Replace with genuine injectors and new seals
- Code injectors to the ECM and road test
Signs your Sprinter needs it

- Black or white smoke and hard starting
- Fuel smell or fuel in the oil
What does injector cleaning and replacement cost?
Ballpark pricing for injector cleaning and replacement on a Sprinter runs $450 to $3,500. The final number depends on your model, mileage, and the exact cause, which we confirm with Xentry before any work is authorized. Diagnostic time is credited toward the repair. See the full pricing page.
Frequently asked questions
Do new injectors need coding?
Yes. Sprinter injectors carry calibration codes that must be entered with Xentry, otherwise the engine runs rough. We always code new injectors before return.
Can injectors be cleaned instead of replaced?
Light deposits can respond to cleaning, but mechanically worn or leaking injectors need replacement. Our testing tells us which path actually fixes your van.
