Is it also possible that some of those codes were already present from the Forge fitting?
Have you cleared them off and then checked again?
i think so, he said "The last code didnt repeat but the top three did after being reset." , still not sure what program there using though
I agree.
I have had a right nightmare with a £20k Snap-On reader (I think it was Solus) - utter shyte, and grossly over-rated. Unfortunately, the collegue who owns it has it on the knock, so can't really get rid of it. It reapeatedly gave the wrong codes on my last S4, failed to interrogate many of the modules, and completely missed a reading from the ESP ECU.
Unfortunately, many of these so called fault code readers, even the professional ones, don't actually read the manufacturer specific codes. They only read the generic EOBD or OBD2 codes, which are just really basic codes.
