Okay so, just got my n55 335 back from bmw, told me it needs a pre cat o2 and a wastegate actuator, im hoping someone has a guide for me to use? Not entirely sure where the correct o2 is located or where the actuator goes, now before you tell me to let them do it they were asking for 1400. Parts are only around 600. So if i dont have to id prefer not to, whatever you got helps thanks!

Did they say bank 1 or 2 for the pre-cat o2? Or is it both?
