· Nozzle gets heated 20°C above set temperature
Maybe you have a 35W heater instead of 25W? You can test the heater wattage if you have an ohm meter - just disconnect it at the PCB and measure the resistance. Wattage = 24 * 24 / resistance
UM2+ has 35W heater and has newer firmware with better PID values.
Anyway you can simply reduce the PID values bye the ratio of power increase. So if you have a 35W heater then reduce all 3 values (P,I,D) by multiplying them all by 25/35. Or you can run the autotune feature.
Cut and paste PID tuning info follows:

35W nozzle versus 25W nozzle and gcodes
Adjusting the 3 PID values is pretty easy - in general you want lower values for higher wattage heater so if your heater is 30% stronger you want to decrease the values by 30%.
The easiest way to play with the PID values for the nozzle are to install pronterface (it's free - you don't even really install it, just download it and run it) which is here:
Then connect a USB from your computer with pronterface to the printer and start it up and connect. It will immediately show the current PID values over on the right side and you can change them. The gcode commands (you can just type in gcode commands in pronterface) are discussed here:
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

Or just choose among these gcodes:
M301 - set PID
M303 - autocalibrate PID
M500 - save PID values (CRITICAL OR YOU LOSE VALUES WHEN YOU POWER CYCLE)
M503 - display PID (and other) values (done automatically on connect by pronterface anyway)
above gcodes explained in detail here:
