Aye checked on the tech2 already...nothing at all showed up? Av changed every sensor possible...strange one eh. Any chance anyone would have the part number of the ecu thats ment to go with that engine as I am not sure if the original GSI ecu is still in the car, as I never did the engine change.

Start car up at any time, and automatically it reeks of fuel, hydrocarbons in emissions test were 1200!!! should be under 200. When I am infront of anyone, all they smell is fuel. After fitting brand new plugs, after 10 mins running plugs are pure black with carbon soot
