Catalogue identity
The TuningService.uk ECU catalogue records EDC16U34 under Bosch EDC16 (catalogue record 112, observed 10 November 2026). The catalogue name is an identification lead; it does not by itself prove vehicle fitment or software compatibility.
This entry is grouped with EDC16U by its catalogue name for navigation. That placement does not establish hardware or calibration equivalence.
Application evidence
AutoTuner lists selected VAG 1.9 and 2.0 TDI unit-injector examples.
Tuning and identification
For the documented unit-injector applications, work from the matched torque request, fuel quantity, injection timing and air/smoke strategy. Confirm software and hardware rather than reusing U1 or U31 addresses.
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 list includes Audi A3 8P 1.9 TDI BLS and Volkswagen Caddy 2K 1.9 TDI BLS entries under EDC16U34. These are individual historical tool-list entries; identify the ECU actually installed. Alientech, PDF pages 13 and 107.
Identification photographThis Audi unit is labelled EDC16U34, Bosch 0 281 013 297 and 03G 906 021 LS. Compare its full label with the EDC16U31 example rather than assuming similar housings imply interchangeable calibrations.Image source and credit: Cartech Electronics.
