Catalogue identity
The TuningService.uk ECU catalogue records EDC16U1 M&S under Bosch EDC16 (catalogue record 1592, 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 EDC16U1 by its catalogue name for navigation. That placement does not establish hardware or calibration equivalence.
Application evidence
Microtronik’s EDC16U1 MS coverage includes the Volkswagen Phaeton 5.0 V10 TDI and Touareg 5.0 V10 TDI. Its broad tool list also includes other engines; the actual ECU identification and installation must be checked before assuming that every listed model has a two-controller arrangement.
Tuning and identification
Volkswagen SSP 304 describes the V10 TDI as two cooperating engine control units serving the cylinder banks, with unit injectors. Identify both controllers and preserve their separate IDs and original reads. Do not presume both controller files or roles are interchangeable.
The unit-injector system calculates injection quantity and controls injection timing; unlike a common-rail application it has no shared high-pressure fuel-rail target. Microtronik’s bench/boot coverage is specific to its tool and does not establish universal methods or map 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.
Identification photograph
Injectronics illustrates the two Volkswagen Touareg V10 EDC16U1 controllers together and associates them with Bosch 0 281 011 481. Its annotations indicate the original master and slave positions. The repairer cautions that the two units cannot be distinguished by appearance once removed, so their positions should be marked before removal.
