Mk2 secondary air pump change

Evening 😊

I have a 2010 Octavia VRS 2ltr petrol and she currently sounds like a VW camper!! Plus the engine warning light is on now. My bf has popped her up on axle stands as he's furloughed atm so got a bit of time and says it's the secondary air pump causing the issues but it's bloody awkward to get to. 

Does anyone know how to go about getting this off or what to remove to get to it? 

Any help is greatly received as obv all garages are shut at the mo and he has the time to look at it. 

Thank you!
