Diagnostic Trouble Codes (DTCs) are fault codes generated by the ECU when a monitored system falls outside its expected parameters. While useful for diagnosing genuine faults, they become a persistent nuisance when triggered by intentional modifications or non-critical sensor issues.

When Is DTC Removal Needed?

  • After hardware modifications — removing DPF, EGR, catalysts, or sensors triggers codes
  • Persistent sensor faults — worn sensors that repeatedly trigger the same code
  • Aftermarket parts — non-OEM components that don't match ECU expected values
  • Limp mode escape — critical for vehicles stuck in reduced performance mode

Key Benefits

Permanent Solution
Unlike clearing codes with a diagnostic tool, we remove the monitoring routine from the ECU. The code cannot return.
Targeted Removal
We only remove the specific codes you request. All other diagnostic monitoring remains fully functional.
Exit Limp Mode
Many fault codes trigger engine limp mode or reduced performance. Removing them restores full power immediately.
P-Code & Manufacturer
We handle both standard OBD-II P-codes and manufacturer-specific codes (VAG, BMW, Mercedes, etc.).

How It Works

Read ECU File
Extract your ECU calibration file and note which DTC codes you need removed.
List Your Codes
Tell us exactly which P-codes or manufacturer codes need removing (e.g., P2002, P0401, P242F).
We Remove
Our engineers disable the specific diagnostic monitoring routines that generate those codes.
Flash & Verify
Write the file, clear adaptations, and verify — the codes are gone permanently.

Frequently Asked Questions

What is the difference between clearing and removing a DTC?

Clearing a DTC with a diagnostic tool erases the stored code but the monitoring is still active — the code will return. Removing a DTC disables the monitoring routine in the ECU calibration, so the code can never trigger again.

Can you remove any fault code?

We can remove virtually any emissions, sensor, or aftertreatment-related DTC. Safety-critical codes (ABS, airbag, steering) are handled case-by-case.

Will this pass an MOT emissions test?

DTC removal is intended for off-road and motorsport use. A vehicle with modified emissions systems may not pass an MOT visual or emissions test.

Can I combine DTC removal with a remap?

Absolutely. DTC removal is often included as part of DPF, EGR, or remap packages when specific codes need suppressing.
