Hopefully you can find the answer to your question there. I'm sure with the bulk of veedub heads on those boards you're bound to find someone that can help

I'm not an expert on automotive computer codes but it sounds like a problem with the Mass Airflow Sensor ( MAS )...the device that detects the amount and density of the air ( partially determined by temperature and humidity ) flowing through the air intake system for the fuel injectors. It sends a signal to the main engine-control-computer to adjust the amount of fuel going into the injectors for the optimum air-fuel mixture for the driving conditions.....warmup, acceleration, transmission gear-shifting, easing off the throttle, etc.....
If the MAS is bad the engine will not start, warmup, or run properly. It will either be too lean or too rich a fuel mixture....or both.
Don't be surprised if you are getting computer-related problems with a Jetta......VW electronics border on being junk, though I know this is not a brand-new car here but a 7-year-old one.

Thats caused by the stock vac lines. I used to work on VW's at Reeve's in Tampa... Simple fix. DEFINITELY DO NOT TAKE TO THE DEALER TO FIX. They will charge you over $100 to fix this, but in actuallity, it takes about 20 min and $3 of vac hose.
What engine do you have? 1.8, 2.0, or VR6? Let me know and Ill let you know where the hoses are.
PM me, Email me, or IM me...

Ok, the fix is fairly simple. I couldn't find a good pic of a Jetta 2.0, but considering they are all the same the Beetle will work just the same.
To get to these, you are going to have to remove the engine cover. Two bolts up front and the cover slides out of the back bolt.
I numbered the ones that I remember were the crap hose. I say crap hose because the hose becomes VERY brittle and dry after a few years, then they crack and eventually break. You will need some pliers to pull off the broken pieces that remain on the nipples. Sometimes, they get so stuck on you might need a razor blade to cut them off. Anyhow, there are only two that I can remember that you will need to replace. The hose you will need to look for under the engine cover looks like this.
They should be pretty easy to spot as there aren't too many of them. If you go the OEM route, the replacements are going to be exactly the same style and look. As you can see, what they give you (and charge you for) is more than you should need. I have about 6 feet of this hose in my tool box from when I used to work at Reeves.
Hopefully, this should cover it. Let me know if you need help finding them. If you still cant find it all of them, take a pic of the engine without the engine cover and Ill point them all out for you... but the pic of the beetle should give you a starting point!

The colored hoses on the Bug have ALL been changed, including non-vac hoses. The #1 and #2 in the pic of the colored hoses should be the only ones you should have to replace. But once you look under the engine cover you will be able to see which hoses they are. And yes, they are all on the top side of the engine with VERY easy access. Matter of fact, the hardest ones to replace were on the 1.8T Beetle...

If you have a OBD2 Scanner/Clearer, that should clear it right up. Plug the reader into the OBD port, then turn the key to ACC. Pull the code on the reader and clear it. Turn the car on and then run a scan again. It should be all cleared up. And yes, I would recommend that you replace all the vac lines. If one is cracked, that usually means the other ones are about to go too.
Clear the code with the car in acc, then unplug the reader. Start the car up fully and let it run for a few minutes. Put the car back into acc and scan again. See what happens.
