Check Injectors Warning

[Juddy]

Hi guys and girls, first time on here and wanted to introduce myself as well as my my problem with my renault megane 2.0 petrol 55 plate. Saying to check injectors which is pretty straight forward but cant quite see how the steel casting in front of the engine comes off in order to get to the injectors underneath! Also it's my second ever Renault as in my late teens i owned a gun metal grey Renault 21 turbo in which was a fantastic car but also liked spending a lot of time in the garage too! Lol. Thanks.
