Black water out of exhaust

I parked my 335 (N54) for a few months during the winter. I do start it occasionally but when I started it yesterday I noticed a lot of black water coming out of the exhaust. I assume it is most likely carbo build up. Is this normal? Should I be worried about engine problems?

The car has no major mods except stage 2 tune and intake.
