is there dirt in my carb?

No, because your car has fuel injection, there is no carb!
There is a small chance the fuel pump has been damaged by running it dry, but I wouldn't expect this in your case.
As long as the car is starting OK now, and there are no running problems orwarning lights on the dash, you should be fine.
Depending on the age/mileage/service history of the car it might be worth changing the fuel filter.
