A2711504279 Mercedes W204 ECU: Exact Part Number, Fitment & Coding

Mercedes W204 ECU A2711504279 is a specific engine-control unit reference. A used ECU should be matched against the complete original label and vehicle specification rather than by model name alone.

Exact-number matching: compare A2711504279 character by character and check connectors, mounting points and other label references. Suffixes and hardware revisions can be important to compatibility.

Do not assume an ECU is faulty simply because a diagnostic code is present. Check power supplies, grounds, wiring, sensors and network communication before replacing a control unit.

BVS identifies this unit for Mercedes-Benz C-Class W204 applications, subject to exact part-number confirmation. The original ECU is the best comparison reference.

Inspect a used ECU for physical damage, corrosion, damaged pins or water ingress. Keep the original module until the replacement has been confirmed as suitable.

Depending on vehicle and module specification, a used ECU may require coding, programming, adaptation or immobiliser configuration after installation. Confirm the required procedure before buying.
