Most modern diesel injectors will need an ECU Correction Code (IMA, C2i-C3i, QR).

When replacing a Diesel Common Rail injector, it is necessary to register the Correction Code, located on the upper part of the injector, into the vehicles ECU.

The Correction Code is used to compensate injector production tolerances, this ensures the ECU balances the injector output to optimise performance and efficiency.
