Injector Tappy noise 1.5dci

Hi, I have just bought a 2010 1.5dci and it drove perfect without issues.
But a few weeks later had a fault code P0204 and went into limp home mode.
The garage replaced the injector in cylinder 4 and coded it into the ECU.
Now it makes a really bad tappity noise especially around 30-35mph when slightly on the gas.
But you can hear it all the time, we swapped back the old failed injector and the noise was gone.
Put a new(different manufacture) injector back in and the noise returned, I've driven it over 200 miles now and the noise is still there.
I've put Shell Ultimate Diesel and injector cleaner but its made now difference.
Has anyone experienced anything similar with new injectors or have any idea what is causing the noise and how to get it to stop?

I have now had all 4 injectors replaced and it's still the same, sounds like an old tractor! Has anyone had anything similar?
