It is sad that "real" automobile mechanics are hard to find.
You are right that some have no clue how to actually troubleshoot, isolate, and resolve a problem when no codes are thrown.
Also, it sounds as if that 19-year old could have got some better "guidance" when purchasing a 1st car that is turbocharged.
Turbocharged VW engines *NEED* to have synthetic oil and hi-octane fuel. If that engine ever had "dyno" oil run in it, it may have suffered from sludging. (oil-passagways getting plugged up).
Also, I assume that "machine shop" checked the planarity of the head while replacing gasket?
At least she is hopefully learning a valuable lesson about buying a car.

Hi there, I have a 2001 Jetta and I am having the EXACT same starting problem. I can't get any answers from anyone either. I've replaced the MAF sensor and fuel filter got a tune up. Nothing.
Let me know if you get any where with this.

I was message 98.
I took off the entire air intake and fuel injector system off the car and gave it a good cleaning. Put everything back together, and it started-up again.
I'm not sure why. But it's working again.

the triangle light with a car and key symbol is the immobilizer. this should mean the key is bad or the convenience module is not recognizing it. it would need a new key or an instrument cluster(convenience module is part of it). as far as overheating goes, make sure you use g12 coolant, it's pink. green coolant will rust and clog everything. honestly, take it too the dealership. there's a lot of "VW specialists" out there that dont really know what they are doing. have a certified dealer look at it and get their opinion, they cost more, but worth it when it's fixed right. make sure your using full synthetic oil in that 1.8t or youll have a new pile of problems.

dilbertsdub did you get it figure out.I have the same issue with 05.5 jetta.Also it had some previous damage on passenger side.It will run for severla minutes after sitting and then it just shut down.I have 4 codes comming up only after it happens-theu are not there while it runs.They are fuel pump rleay circuit,both O2 sensor circuits and MAF citcuit.THe car ran fine until yesterday.When it warms up in like 305 minutes it won't start,then again it will start in like 10 minutes,but will run only for few seconds or a minute max.I am confused by it.

I have no damage to any part of my car; Apparently my dealer seems to think its been involved in an accident (this would be their answer to any/and or all my vehicles issues).... After they replaced the battery, fuses, ignition control module and altenator my vehicle finally starts,...however now it seems the problem is electrical as my sunroof opens and sometimes whenever it pleases.

A couple weeks ago my car (w/ 125,000 miles) was indicating that a door was ajar, from the drivers door I couldn't control any of the power windows, mirrors, locks or release the fuel door. Everything else appeared to run just fine about 30- 45 minutes down the road I the car stalled, I lost all power to the ignition. After the car set on the shoulder for 10- 15 minutes it started just fine, ran for another 30- 45 minutes same thing. Sometimes it run longer, sometimes shorter, the time also varies between stall and re-start with the longest being approx. 45 minutes.
The door problem was diagnosed as bad cables to the door control system and is now currently fixed. I was also told that one of my glow plugs was bad so they were all replaced. While running my car through the diagnostics after the aforementioned maintenance the car stalled out again.
Has anyone encountered similar problems and if so, what was the cause?
Thanks in advance for help you may provide.

I think I know what is going on... but lets be clear on some things.
1) There is no "ignition" on a diesel engine - as long as fuel is injected and there is air... it will run.
2) The glowplugs have absolutely nothing to do with running the engine. They are only used during starting the engine below about 40F degrees.
Given the above, we can make the assumption that perhaps the supply of fuel to the engine may be a problem. It sure sounds like you are describing EXACTLY what "gelling" of the fuel would do to the engine. (Start fine - run for awhile and quit)
I would suggest you replace the fuel-filter and make certain you have added anti-gell to the fueltank. The WHITE bottle of "Power Service" available at Walmart is a very good product to use in the winter for EVERY fillup. (about 6oz per tank full)
I would expect that to resolve your stalling problem
