The 1.7 engine in later common rail type injection system are notorious for injector noise,
I am a Vauxhall tech, we get lots of high mileage fleet cars with very noisy injectors and they just keep on running.
You could possibly make sure they are coded correctly at a main dealer, they have numbers on the top of injectors, which should match the code programmed in the engine ECM.
Another idea would be to get the small quantity adjustment checked/ programmed.
If its not horrifically noisey you could ignore it!
Hope I helped a little....
