DTC Off
Error Code Removal
What Is It
Diagnostic Trouble Codes can trigger limp mode, check engine lights, and prevent your car from performing at its best. We permanently remove specific DTCs from the ECU calibration — not just clear them with a scanner. The codes won't come back after restart.
Benefits
When You Need It
After removing DPF, EGR, catalytic converter, or any emissions hardware. Also useful for persistent sensor faults on older vehicles.

Frequently asked
What is DTC Off?
Diagnostic Trouble Codes can trigger limp mode, check engine lights, and prevent your car from performing at its best. We permanently remove specific DTCs from the ECU calibration — not just clear them with a scanner. The codes won't come back after restart.
How much does DTC Off cost?
From €200. Combined solutions are cheaper bundled — send your make/model/year for an exact quote.
Will it damage my engine?
Done properly — custom on your own ECU, calibrated, with your original file saved — no. A cheap generic file can. We never flash a random database file.
Which cars do you cover?
Most modern diesels (VW, Audi, BMW, Mercedes, Ford, Opel and more) and many petrol cars. Send us your make, model and year and we’ll confirm.
Do you use generic files from the internet?
Never. Every solution is developed on your own ECU file with master tools, and your original is always saved so it can be put back.
