Looking for Launch X 431 Pro 5 users, or launch diag. users, I got few questions to ask.

So I am about to buy Launch X 431 Pro 5 and I got few questions about it. Is ADAS just a addon or I can atleast diagnostic the adas systems like Radar is missaligned or camera needs calibration ect, and how is reprogramming and programming a ECU working, is DPF, EGR and Urea injector removal possible, ofc. I am not looking for a ECU Tuning tool, but if it can do it thats a plus. And what about secret options that are left out by factory can they be turned on with this tool?
