Catalogue identity
The TuningService.uk ECU catalogue records EDC16CP34 under Bosch EDC16 (catalogue record 66, 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 Volkswagen/Audi 2.5, 2.7 and 3.0 TDI applications. Alientech lists an Audi A4 2.7 TDI BPP example; Audi describes BPP with EDC16CP+ common rail.
Tuning and identification
For that common-rail example, rail-pressure control is part of the fuel-system context alongside torque, air, injection timing and duration. Do not transfer a VAG PD calibration to it.
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 historical list also includes Hyundai Seasall S-series 3.0 V6 CRDi marine entries under EDC16CP34. These are separate applications from the Audi and Volkswagen examples and do not imply interchangeable calibrations. Alientech, 2017, PDF page 7. The documented Audi BPP and Volkswagen common-rail examples are compared in EDC16 injection systems and vehicle examples.
For specific Crafter 2.5 TDI examples and a comparison with listed EDC17 applications, see EDC16CP34 Crafter.
Identification photograph
This Audi-labelled example shows Bosch 0 281 014 376 and Audi 4F9 910 401 B. The source identifies it as an EDC16CP34-4.5 from an A6 3.0 TDI; the suffix is not independently legible in the image.
