My Jetta (2.0L) has about 80k miles on it now. Anything need checked on or serviced? I just had the oil changed (done every 5k miles). Timing belt? Fuel system? Anything, or just keep driving it? I don't have a manual for the car.

Ricardo, I need juan manuel por favor.

Service at 80,000 miles:
spark plugs
air filter
pollen filter
oil/filter change
we also do a tire rotation, obd/ dtc inspection, checklist stuff.
timing belt due at 100,000 miles/ 5 years.  Be mindful of this one.  If you pop the belt, valves will be bent on a 2.0 liter.

Sorry, Russ....been a bit busy/ haven't been on here in a while.
Pollen Filter is located in the upper plenum area, base of the windshield.  the cover is the one on the passenger side with the four screws in it.  Be advised that most people break one of the tabs off when putting the cover back in when trying to do this one, thoough.  It can be tricky the way that it fits in place.  be careful and take your time, you should be O.K.
