A6469003900 0281016862 – ECU ENGINE CONTROLLER Mercedes 2.2 CDI CR4.20 VIRGIN Ready for Adaptation
ECU ENGINE CONTROLLER A6469003900 / Bosch 0281016862 designed for Mercedes-Benz vehicles equipped with the 2.2 CDI diesel engine and Common Rail CR4.20 injection system. The module is supplied in VIRGIN condition, meaning all data from the previous vehicle has been completely removed and the ECU is ready for programming and adaptation in another vehicle.
Each engine controller is fully tested (bench test + diagnostic communication verification) and covered by warranty. This solution is ideal when the original ECU is damaged, cloning is not possible or the original module no longer communicates with the vehicle.

Vehicle compatibility
The ECU ENGINE CONTROLLER A6469003900 / 0281016862 was installed in selected Mercedes-Benz vehicles equipped with the OM646 2.2 CDI engine:
- Mercedes-Benz Sprinter W906 – 2.2 CDI
- Mercedes-Benz Vito W639 – 2.2 CDI
- Mercedes-Benz Viano W639 – 2.2 CDI
- Selected commercial and fleet versions using CR4.20
Production years: approximately 2006–2012 depending on market and equipment version.
Engine codes: OM646 (different power variants)
IMPORTANT: compatibility must always be verified using the exact ECU part number. Matching by vehicle model alone is not sufficient.
What does VIRGIN mean?
A VIRGIN ECU ENGINE CONTROLLER has been completely cleared from immobilizer data and information stored from the previous vehicle. After installation, the module behaves like a brand-new factory ECU.
- no VIN stored,
- no immobilizer synchronization,
- ready for adaptation in another vehicle.
Adaptation and programming
After installing the A6469003900 ECU, adaptation in the vehicle is required:
- diagnostic tool: Mercedes Star Diagnosis / Xentry
- procedure: immobilizer synchronization (Drive Authorization)
- SCN coding if required
The process is identical to installing a new ECU from Mercedes-Benz and does not require additional memory modification.
Common ECU faults
- no communication with ECU via CAN or OBD,
- vehicle does not start,
- injector control problems,
- damage after short circuit or water ingress,
- unstable engine operation.
FAQ – Frequently Asked Questions
Does ECU A6469003900 0281016862 fit Mercedes Sprinter 2.2 CDI?
Yes, if the ECU numbers A6469003900 or 0281016862 match and the vehicle uses the CR4.20 system. Compatibility should always be confirmed using the original part number.
Does ECU 0281016862 for Mercedes Vito W639 require programming?
Yes. This is a VIRGIN ECU ENGINE CONTROLLER, therefore adaptation using Star Diagnosis or Xentry is required after installation.
Is ECU A6469003900 Plug & Play?
No. Immobilizer synchronization and coding are required. Plug & Play operation is only possible when cloning data from the original ECU.
How do I adapt ECU 0281016862 in Mercedes Viano 2.2 CDI?
Install the ECU and perform Drive Authorization adaptation using Mercedes Star Diagnosis or Xentry. The procedure is identical to installing a new ECU.
Does A6469003900 support the OM646 engine?
Yes, this engine controller is designed for Mercedes-Benz 2.2 CDI OM646 engines using the CR4.20 injection system.
Can ECU 0281016862 be installed without coding in Sprinter 2.2 CDI?
No. Immobilizer synchronization and coding are required after installation.
What should I check if Mercedes 2.2 CDI ECU does not communicate?
First verify power supply, grounds and CAN communication in the vehicle. If the ECU also fails to communicate on the bench, replacement is usually necessary.
Can A6469003900 replace a damaged Mercedes ECU?
Yes. It is a fully tested engine controller prepared for adaptation as a replacement ECU.
Which diagnostic tool is recommended for adapting ECU 0281016862?
Mercedes Star Diagnosis / Xentry is the recommended solution because it provides full compatibility and proper SCN coding support.
