Red Stop Engine Light

First thing you need to do is an EGR Tuneup. Rawze has the videos on how you do this above in the video section. That is where I would start and do it yourself. Simple hand tools are all you will need, along with the sensors and possibly a new doser as they do fail. A case of Carb Cleaner too, as your motor is more than likely clogged with soot. Watch the videos.
