Hello, I never actually changed my TFM coupler, but after checking, there are no apparent damages on it, no burns or anything... Should I change it anyways ?

Can you share a picture of it? Just because it doesn't look burnt doesn't mean it's not worn out. The more subtle wear and tear signs are:
* It's not round anymore
* The opening at the bottom is wider than it used to be
* Scraggly edges/lips that will catch the filament.
How many print hours are on your printer? Maintenance --> Advanced --> Runtime Stats.

I'd go ahead and change the coupler. Better safe than sorry, and it does look like it's got wear on it, even without heat discoloration.

Nylon tends to be a bit rough on your TFM coupler. How many print hours since the last time you changed it out?
