Those are not the passenger car market. There aren't alot of diesel cars in the US yet.
the big truck people are running as much fuel as possible, and need to drop the EGTs.
The veggie market is wants the cheapest possible, even washer fluid pump would be fine.
The passenger diesel will have to come from your side of the pond.
Watch this one I guess from your side
