Try to clean your ECU connector from the top,take off negative terminal from battery first.

Hi KDD5

Did you manage to sort the problem as I have a similar issue.

When you fitted the new (reconditioned) injector, did you have to reprogram the ECU with the injector code?
My Qashqai has just started to misfire, and produced error code P0203 Injector 3 Circuit Open.

On resetting the code the fault clears for a while and the car drives fine. I cant find what triggers the injector to cause a missfire again (no specific high ref or time driving).

I have swapped the injector with the one next to it, and the fault follows the injector to the new cylinder.

Thank you for any advice
