Hi,

My issue is that my car starts to judder as it accelerates through 2000rpm. The garage has said there is a diagnostic code P0202-12 (injector 2). He has suggested that rather than replace the injector, I try a fuel additive to see if it flushes out any blockage. He also said he is normally 'very-anti- using fuel additives, but in this case it might work. He has recommended I ask on a forum if anyone has tried this before with success and if so what fuel additive was used.

Regards,

Darren

I literally have just used a fuel additive to clear dpf and egr valve and after a day and a few runs the fault codes have cleared. I would say try it what's the worse that can happen!
