2013 328i C1440 Wastegate (replacement) question..

[MTXRooster]

Got this code on my car the other day, says wastegate actuator malfunction - check engine light and of course, car in 'limp mode' (no turbo due to the wastegate malfunction).

Been searching other forums via google on replacing it and 2/3 the posts claim it's an easy fix, as simple as unbolting the old, and hooking up the new (it's electronic wastegate, not vacuum one, if it matters).
Then there's that one website..... Where everyone is saying you MUST calibrate it properly for it to work.

Anyone know the actual answer? Has anyone here done one? I have no problem swapping it out, not at all. But if it needs to be calibrated, that's not something in the scope/depth of my comfort. I've read on how you need ISTA+ and a special cable, it's the actual doing it that worries me, don't want to wreck my turbo/engine/car. Don't have the software nor the tool atm regardless, lol, but I'm just scratchin my head how 2 large threads differ with a third (meaning, why are some saying it's required and many are not mentioning they had to do it at all! lol).

Thanks in advance for ANY input/advice/suggestions you can offer.

It's not so much a calibration, but an adjustment. The wastegate actuator uses a threaded rod with nuts on each side of the arm to lock it in place. It must be adjusted after it is replaced to ensure that the wastegate is fully closed, and fully open in each position of the actuator.
