Posted what is below on a VW forum about 3 weeks ago now... still no responses. The forum kinda sucks.

Just bought a 2000 Jetta GLS 2.0 5spd with 155k on the clock as a commuter car. Knew it had a few issues when I bought it but nothing seemed major and the mechanic that looked it over seemed to think the same.

For starters, the airbag light is on. My first thought was the clockspring but the horn still works so I'm guessing it'll need to be scanned?

Second, the cruise control will cut out seemingly randomly and won't work again until the car is restarted. Really not sure whats going on with that one. I heard these are notorious for bad brake light switches though (also get interference through the radio with an FM adapter when stepping on the brakes).

Third, there is some sort of noise coming from the engine bay. Sounds like a metallic grinding/whistling noise of sorts, like one of the pulleys on the serp. belt had a bad bearing. Took the belt off and everything spun free and smooth (does need a new belt though). The noise is correlated with hard acceleration and/or heavy load. Doesn't seem to be an exhaust leak so I'm down to thinking maybe a vacuum leak? After sucking in some seafoam smoke came out the end of the exhaust and nowhere else.

Finally, It's got a few suspension clunks. Seems like mostly from the rear. Maybe a little from the front passenger side too. Not sure what the most likely culprit is there, control arm bushings? Rear had a broken spring. Both were replaced with a new set. Didn't see anything else glaring.

Airbag light is more than likely a programming issue and can be scanned out. Loss of cruise usually means a bad second brake light switch (VW used two, one for the lights, one to cut off the cruise, for a while) and easily fixed. Any noise from the engine means take a hard look at the whole system of pulleys and idlers in the timing belt system and the water pump. Good dealers carry every pulley and idler and water pump for that reason. Suspension noise is almost always rubber insulators gone bad. Lots of bushings and pucks under the VW. 2000 was the first year I worked for VW and 2011 was the last.

does your cruise have steering wheel mounted controls ? if so I would suspect the clock spring for that reason and the airbag light even if the horn still works

Knew I could count on this forum! Some great info here, thank you. Trying to get it to the shop soonish (stripped out one of the security lugs....) and I'll have them check out the airbag light while it's there. Weirdly it seems like changing the dipstick tube helped solve the under hood noise though it isn't completely gone. Guess it was causing a vacuum leak since it now starts easier and idles smoother. I figured the suspension noise is rubber parts gone bad, just hoping it's not axle bushings. Also noticed that the front tires are wearing unevenly. All in all it seems like a good car though.

tinytrax78, cruise is mounted on a stalk off the column.
