helloo, Just picked up my new gti yesterday

Amazeing car! 05 with only 40000 miles and heated leather seats. Looking at the engine its slightly dirty and looking down there is some bits that are covered up and under the actual engine its got a hole. Looks square so doupt a cover has been ripped off. I just sold my cupra tdi and it had a complete underengine cover which you couldn;t see through and kep the engine nice and clean. I know the m4 gtis have the same. Should there be a complete cover under mine? If so I am getting one because I love the engine to be all clean (sad as it may be lol)
Thanks
