Injector causing erratic idling

[Rebecca_Taylor90]

Does anybody have experience with injector cleaning that was successful, or is it a load of snake oil? It's possible that I could find out for about ten pounds...

When my 320d was battling with two injectors, I tried Wynns diesel fuel system cleanser and Millers Ecomax.

Personally, I believe they were too damaged to discern the difference, so I replaced them.

In retrospect, I should have done all four since one of the originals is on its way now.

Replace your copper washers as well.

Thanks, I think one or two of mine are going, but the other two seem fine for now. Considering how much it costs, I might do two now and two later. Where do the washers come from?

Yes, however it may be modified without disrupting the chain if a sowcisl tool is used in the timing cover.

I am competent enough to attempt to remove the injectors, but I am incapable of replacing the HPFP. Hopefully, only the injectors require maintenance. However, thank you for the advice. I looked for a sowcisl instrument for ten minutes before concluding that you may have misspelt special haha'

Haha, I hate my big fingers, my phone, and predictive text. True, it is a unique instrument
