Catalogue identity
The TuningService.uk ECU catalogue records EDC16C31 M&S under Bosch EDC16 (catalogue record 1578, 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 EDC16C31 by its catalogue name for navigation. That placement does not establish hardware or calibration equivalence.
Application evidence
An Alientech K-Suite 4.18 compatibility announcement reproduced by Evolved Tuning lists the BMW 7 Series E65 740d automatic as EDC16C31 M&S. TRW’s diagnostic application list independently identifies master and slave Bosch DDE 5.1 controllers on the E65 740d M67. These references support that example; confirm the exact installed ECU and software.
Tuning and identification
For the documented E65 740d installation, identify the master and slave separately, record their individual hardware/software IDs and keep the corresponding original reads. Do not assume the two controller files, definitions or roles are identical.
The Alientech announcement describes service-mode support for its own K-TAG release. Read/write and recovery options remain dependent on the current tool, ECU and software; this is not proof of a distinct universal torque-map layout.
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
This BMW 740d ECU is labelled Bosch 0 281 010 899 and DDE 7 791 572. A file listing identifies 0281010899 as EDC16C31 for the 740d, and a K-TAG application list describes a 740d EDC16C31 master/slave setup. Bosch Electronic Service and the photograph supplier both identify this part as EDC16C1, while the file listing calls it C31. The K-TAG application list does not tie its C31 master/slave entry to this exact part number. The name is therefore disputed; verify the actual tool and software identification. The photo shows one unit and cannot establish its original role.
