The DTC (Diagnostics Trouble Code) removal service allows to remove individual error codes from the ECU firmware permanently. This is not the same as erasing DTCs using a diagnostics tester, which is only a temporary solution.
With this service, the DTCs are removed from the ECU software, making them not be part of the system anymore and not show up in scans or the dashboard, even if the issue is still present.
This can be very useful if you want to remove some parts from electronic systems such as EGR, intake flaps, etc.
