    The blue haze is likely an exhaust leak. Broke flex pipe? The smoke will intensify when dosing is occuring. Unrelated to the engine lights.

    I will have a look at the flex pipe, is replacing doser or 7th DYI or still a dealer thing or someone with a davie? Derate is not active at the moment.

    Its no walk in the park. I have had experienced techs struggle with this one. Take a look where it is under the crook in the Cobra pipe. You make the call.

    I normally drop the exhaust pipe to clean and flow test the doser. Way faster than removing the doser.

    lol ya have to walk away and take a break several times when replacing those 7th injectors. They are definitely not a diy project for most people.
