So can I insist that they change out the part or do they have to pull the DTC first before they can act? I have a tendency to keep my cars long term and my fear is that when I do travel to a cold area that this could be damaging later.
In my case the technician reported on the work order that he recovered DTC P0302 (although the Check Engine light had never
come on) and referred to the Canadian bulletin regarding the updated intake manifold.
If the code doesn't show up on your car, but it was built prior to the production change for US models, your dealer may be willing to replace the manifold as a preventive measure. Let us know what happens.
