I am a former technician.

Your pictures do not do much justice. However, the weakest link on those 1.8T cars is not the belt itself, usually the tensioner goes bad. It is very unlikely that when tbelt failure happens due to belt giving up.

Parts are relatively inexpensive. It is very DIY friendly. On that Jetta, I can do it in 45 min to an hour, but I have done over 100 1.8T (incl AMU motors on TT 225s) and every imaginable audi/vw with timing belt. You should be able to knock it out in couple of hours if you prepare.

Satisfying job too. Let me know if you have questions.
