Description
OEM number A6111537379. Genuine used and tested Engine ECU Module for the <a href="/brand/mercedes-benz“>Mercedes-Benz W203 C-Class CDI (2000–2007). This original equipment unit was carefully extracted from a salvaged vehicle, tested against factory performance parameters, and dispatched in confirmed working condition. ¶ This engine ECU manages diesel injection event sequencing, multiple injection strategies including post-injection for regeneration, and torque limitation during transmission upshifts on the W203 CDI. It interfaces via the CAN bus with the ESP and transmission control modules to ensure consistent, safe torque delivery across all driving conditions. ¶ Failure of this module may lead to rough idle, visible exhaust smoke particularly on acceleration, refusal to rev beyond a low threshold in limp mode, or complete engine shutdown. Stored fault codes may include injection quantity deviations, communication errors on the CAN bus, or torque model plausibility faults. ¶ Tested and confirmed working, this used OEM unit was taken from a written-off Mercedes-Benz W203. Verify that OEM reference A6111537379 corresponds to your vehicle before ordering. Specialist installation is advised and ECU coding including injector quantity adjustment and software adaptation must be completed after fitting.

No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
