Thanks Focus. Completely understand
This I understand, whether we agree or not, the dealership will still VOID the warranty. Not the complete warranty but your car is now re flagged for modifications. The time spent to try a get them to warranty something will be hell and it is not worth getting stressed out about it, whether it be a pump, sensor or whatever...
