PSA EDC16 DTC Remover — Peugeot and Citroen ECU File Editor 1.0.0.0

PSA EDC16 DTC Remover is an offline binary editor for supported Peugeot and Citroen Bosch EDC16 engine-control files. It locates recognized diagnostic-trouble-code table entries, shows their addresses and mapped codes, lets the operator select individual records and saves a separately named modified file.

Supported vehicles, ECUs and files​#

The target family is PSA Bosch EDC16, but internal layouts differ across EDC16C0, EDC16C34, EDC16CP39 and software revisions commonly encountered in Peugeot/Citroen work. The packaged program does not include a definitive ECU list, so support must be established when the exact binary is recognized and the displayed DTC table is structurally plausible.

• Peugeot and Citroen EDC16 binaries whose DTC table layout is implemented by the application.
• Individual DTC entries displayed with address, stored value and interpreted fault code.
• DPF and EGR status information where those flags are recognized by the file parser.
• Offline file editing only; no ECU read/write communication is included.

Functions​#

• Open a full ECU binary and scan for the supported table structure.
• Review multiple DTC slots and select only the intended records.
• Mark selected entries for removal and save an output with a distinct filename suffix.
• Display the application’s DPF/EGR status without claiming a full diagnostic scan.

System and hardware requirements​#

• A Windows PC with a compatible .NET Framework environment.
• A complete BDM/bench/boot/OBD read appropriate to the exact EDC16 and programming tool.
• Verified ECU hardware/software identification and a diagnostic report tying the code to a repaired or intentionally altered function.
• External checksum correction/verification and stable programming power where required.

Recommended workflow​#

1. Diagnose and repair the underlying fault first; save DTC and freeze-frame evidence.
2. Hash the untouched full read and open only a copy.
3. Confirm each displayed code/address is credible, remove the minimum intended entry and compare every changed byte.
4. Correct checksums if needed, program with recovery available and verify that unrelated diagnostics still operate.

Package contents​#

The archive contains one unsigned x86 .NET application. No PSA interface, driver, ECU database, checksum plug-in or flashing tool is included. It was inspected statically and never executed during preparation.

Important limits​#

The name EDC16 is not sufficient evidence of support, and indiscriminate DTC suppression can mask unsafe faults. Emissions-related changes can be prohibited for road vehicles; use only for lawful authorized work and never as a substitute for diagnosis.
