Printing fine, then next day feeder starts skipping/going backwards rapidly for half a second now and then
What you are referring to as the culprit is the white PTFE coupler, which indeed can start showing signs of wear. Looks like you found it!
It is hard to pinpoint an exact number of print hours on it, since it continuously receives pressure from the spring above it and what filaments you print (how hot your hot end gets) is also influential.
The fact that it is a consumable and can show signs of wear is a fact though.
With the Ultimaker 2+ we have replaced the spring by a spacer, and replaced the PTFE by a glassfilled PTFE, which is stronger than the 'old' one. If you still had the old one, a new one may last longer.
About error 2, why would you want to move the printhead so fast?
What probably happens, although with filament is seems unlikely unless you move it really really fast, is that you make the steppermotors turn, which generate some power which make it to your electronics. That may probably cause it to freeze.
Best remedy is.. don't move it too fast manually
