After being away from this game for god knows how how long I noticed that there is a new difficulty and after some Googleing I found that it adds more loot, harder enemies and so on but one thing I couldn't find was how the leveling works. Does starting it add more levels or do you have to DL the more levels DLC? I have no urge to level up anymore as I spent way to long grinding for my current stockpile of legendaries but I kinda want to try out UVHM.

Everything auto scales to your level. You have to either have the season pass or purchase the DLC to get the extra levels and loot. There are 2 UVHP's now, having both makes your total level cap 72(plus 8 "OP" levels, which was Gearbox's way of giving us 8 more levels beyond 72 without skill points).
