Catalogue identity
The TuningService.uk ECU catalogue records EDC16C3 under Bosch EDC16 (catalogue record 38, observed 10 November 2026). The catalogue name is an identification lead; it does not by itself prove vehicle fitment or software compatibility.
Application evidence
AutoTuner lists selected Peugeot 1.4 HDi examples; Citroën service information also groups EDC16C3 and C34 diagnostics for 1.4/1.6 HDi vehicles.
Tuning and identification
C3 and C34 are both encountered around PSA small diesels, but a shared vehicle name does not make their maps or definitions interchangeable.
Read EDC16 torque fuel and tuning basics and EDC16 variant application and tuning differences for the shared context. Examples are not an exhaustive fitment list; check the installed ECU and current tool documentation.
Additional source evidence
Alientech’s 2017 list also identifies EDC16C3 in selected Ford Focus 1.6 TDCi G8DA/HHDA and Mazda 3 1.6 MZR-CD Y6 entries. These are the tool list’s examples and do not establish the ECU fitted to every vehicle with those engines. Alientech, PDF pages 49 and 70.
Citroën’s 2008 bulletin includes configuration and diagnostic notes for specified C3/C34 1.4/1.6 HDi installations. See EDC16 diagnostic data and configuration examples for the scoped details.
Additional identification and diagnostics
AutoTuner’s Peugeot compatibility list includes 206 1.4 HDi entries under both EDC16C3 MPC556 and EDC16C34 MPC562. The model and engine description alone therefore cannot determine the installed controller. AutoTuner Peugeot compatibility.
Identification photograph
The pictured label reads EDC16C3 and Bosch 0 281 010 390; the listing associates this example with a Peugeot 307 1.4 HDi. The label is more useful than the housing shape alone when identifying the unit.
