hi all, so ive recently purchased a insignia 1.8. was really happy with it till i noticed code 3 on the dash. Ive done lot of research and discovered a few common faults. one being the header tank cracked..I've replaced this. One other thing i found was the egr and egr cooler but it didnt specify petrol or diesel. does anyone know if my insignia has an egr, if so where is it?! having never owned a 1.8 im unsure as to weather theres a lack of power but i am only getting 21.something mpg which according to google is really low. my 1.6 focus got 26mpg! any help on this would be appreciated!
