Injectors diagnostic values

[gixxera]

Hi all,
My car is Citroen C5 2.0HDI 163hp, 2010
Could you please give me an advice about the values about the injectors on the picture below?

I see that all values for the 4 injectors are higher than usual. Is this can be a serious problem? The engine has not any symptoms as trembling, trimming or so. It works absolutely normally. The only opinion that I have received is that maybe it is caused because of bad fuel. Should I have to put some kind of additive in the fuel? I usually use BDC sometimes.
