Catalogue identity
The TuningService.uk ECU catalogue records EDC16UC40 under Bosch EDC16 (catalogue record 1595, observed 10 November 2026). The catalogue name is an identification lead; it does not by itself prove vehicle fitment or software compatibility.
Application evidence
Bosch Electronic Service identifies EDC16UC40 part 0281020134 with a Yuchai Machinery application.
Tuning and identification
This documented machinery example needs its own engine, duty-cycle and ECU identification; do not infer the same calibration or compatibility from the similarly named U40.
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 identification and diagnostics
For the specific Yuchai Machinery entry, Bosch’s service listing identifies part 0281020134 with a 116 kW application and a listing beginning in October 2007. Bosch gives possible fault patterns for that part including P062F EEPROM error, communication failure and connector water damage. These are possible symptoms, not proof that the ECU itself is defective. Bosch Electronic Service, part 0281020134.
