Been scrolling through the various codes etc by using the TEST facility on my car and came across r 0209 and Er 0209. I notied on the list of fault codes in the sticky thread that P0209 is an injector circuit fault, and was wondering if they were the same thing or what mine meant? Are they fault codes or just a general part of the readout? If they are fault codes then what do they mean? I also came across one that flashes alternatley between dtc and NONE. What does that mean? Is there something missing? Car drives fine by the way so not aware of any probs.
