CXXB Injectors - extreme nail biting and restless legs

With the Golf 7 (2016, 1.6TDI 110hp), the diesel pump had failed.

A reconditioned diesel pump and injectors from the same supplier were installed. The fuel rail was replaced, and the tank and lines were cleaned.

However, the problem now is that the car is running very rough (and getting worse) and also runs unevenly at idle.

The injectors from the supplier don't seem to be the best choice.

I now want to use VCDS to find out which injector(s) are causing the problem.

However, there are no injection quantity deviations in the extended measurement values, only injection time deviations, which I can't really work with.

The Delphi tester also doesn't help me here. Does the CXXB have injection quantity deviations?

Hi,
with my 1.6l TDI DDYA, this is the case. You can directly deduce the injection quantity deviation from the given injection time deviation.

Question: Can I use a scan tool?

It is possible that the system was not 100% free of debris.
