E212 200cdi misfire

My car has a part throttle misfire, there is no smoke from any unburnt fuel, does anyone have any experience with this?
Also, about fuel system cleaners and de-carbonising treatments, does anyone have an opinion on these and their benefits.

Could do with error codes being read, but possibly injectors, fuel filter, fuel pump

Thanks, I will start with a fuel filter renewal.
