While intake was out may aswell paint it, if all else fails spray parts in the boot of your old Audi A3 diesel.

Turbo to be replaced however removal of downpipe required to clear studs on turbo so sports cat replaced with decat downpipe.
5x turbo housing bolts look horrific but actually came off quite easy, however
2x downpipe bolts under car were moulded to the car.....hacksaw
