My personal belief is that the fuel filter will probably have to be changed a couple of times.

IIRC, the gasoline will probably dissolve the diesel, so I don't think it will really stay resident in the fuel system for long (especially with ethanol in the fuel).

I would get a written statement from the gas station that they filled it with diesel and they will pay for any repairs. I would then do what the dealer recomends, then wait and see.
