No. This is an original ECU that has been tested, prepared in VIRGIN state (cleared of previous vehicle data), fully functional, and ready for coding.

2. What does VIRGIN state mean – is coding required after installation?
Yes. VIRGIN state means it is not assigned to any vehicle, so after installation it must be coded/adapted to your car (immobiliser, variant configuration).

3. Which tools can code this ECU in a Mercedes?
Recommended tools: Star Diagnosis / Xentry (DAS). It’s also possible to use compatible J2534 interfaces working with Xentry.

4. Which models and years is A6421500872 / 0281014341 compatible with?
For 3.0 CDI OM642 engines in: E-Class (W211, W212), ML (W164), GL (X164), S-Class (W221), R-Class (W251) from around 2005–2011. Always compare part numbers with your ECU label.

5. What tests are performed before shipping?
CAN communication, power supply, and I/O line tests on a bench, memory verification, and start-up/operation in a reference vehicle – full functionality confirmed.

6. Will a VIRGIN ECU start the engine without immobiliser pairing?
No. VIRGIN requires immobiliser pairing. Immobiliser-off options are not part of the standard setup – ask if you need a different configuration.
