I have had it on the formidable version 2 and it brings up a few codes

P0404
P0405
P0406
P0409

Now they all state something to do with the EGR I ve had it off cleaned it blanked it and still no difference

I ve cleared the codes and they haven't come back so I don't really know if the egr is working or not so might jus cough up and get a new one to see if that sorts it
