Have you done anything different to this car recently? Has anyone else
serviced it recently? If so, perhaps something was not connected right.
Sometimes when you have a key ring with a zillion keys weighing it down it could affect your ignition switch! Try a different key.
Maybe you need a tuneup if you haven't had one in years!
If you have an automatic it won't start until you put your foot on the brake - there is a switch on that brake that could be defective.
Bad fuel or fuel starvation could cause some stalling too!
I had a car once that developed a small hole in a rubber fuel line causing the car to **** air and stall. Check you fuel lines especially if they are rubber.

SOURCE: 02 Jetta 2.0 Check Engine Light
Hi, only way to really know what the check engine light is for is to run a diagnostic check on the pcm using a OBD II diagnostics tool, you can buy one at most auto parts store's or if you don't want to spend the money on one some auto parts store's will do a diagnostics check on your vehicle for free, good luck.

Before you do anything else you are just going to have to read the codes. So buy the maintance book at autozone,locate the little juction box on the fire wall and jump the terminals with a little wire. Then of course sit in the drivers seat turn on the key(do not start) and read the blinks. Then you will know what the problem is.

There is no p01001, it's either p0100, or p0101.
Anyway, it's the mass air flow sensor that's bad. The p0171 and p0174 is a lean condition on bank 1 and bank 2, which are the oxygen sensors. Change the mass air flow sensor and that should take care of the p0171 and 74 codes.
The mass air flow sensor can cause the 02 sensors to read lean.
The u1301, is a class 2 circuit short to battery. That, you have to test wires to find with a voltmeter/continuity tester.
I would try and find that short before changing the flow sensor, you don't need the new one shorting out, they are not that cheap.
