Catalogue identity
The TuningService.uk ECU catalogue records EDC16C9 under Bosch EDC16 (catalogue record 59, 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 Opel 1.7 and 1.9 CDTI and Saab 1.9 TiD applications.
Tuning and identification
C9 and C39 both appear in tool coverage for some 1.9 diesel families. Identify the installed ECU and firmware instead of choosing a definition from engine size alone.
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.
Further application examples
Alientech’s 2017 table includes a Fiat Idea 1.9 JTD entry, an Opel Astra 1.7 CDTI Z17DTL entry and a Saab 9-3 1.9 TiD Z19DT entry under EDC16C9. These are dated examples rather than a complete application list. Alientech, PDF pages 45, 81 and 94.
