on a non turbo s4 (probably s5 too) you can change your secondary injectors by just removing the intake pipe for access, it's very easy.

No you don't remove the UIM...they're practically staring at you. The secondary fuel rail is right below the intake pipe/hose...or towards the passenger side of the throttle body. I'm not sure if there is any difference from N/A to Turbo...if there is then disregard.
