DTC OFF

Disable fault codes in the ECU

DTC OFF deactivates specific fault codes in the engine controller. The MIL turns off after removing DPF, EGR, catalytic converter or other parts, and the ECU keeps running cleanly.

Benefits

  • No check engine light after mods
  • Selective deactivation
  • Other diagnostics remain
  • Combine with DPF / EGR / AdBlue OFF

For whom

Workshops and tuners who want a clean ECU after mechanical modifications.

Frequently asked questions

Are ALL fault codes removed?

No — only the ones you want. Safety alerts stay active.

Will it still pass MOT/TÜV?

Depends on the country and which codes are off. Ask your tuner in advance.
