I've been a member for about 3 months now and a observer for over a year, and, thanks to the information on the site, I decided finally, when I found the right 'deal' to buy an '04 2.0L Passat PD(?).
Love the Car, it had about 93k on it when I purchase, I made the purchase of this particular vehicle based on the fact that the previous owner was on a first name basis w/ the dealership from which she traded the vehicle for a newer (gasser). They had maintenance records every 3-5k for one thing or another (She sounded pretty AR about her car; good for me)
The Last night, I ventured out w/ my 3yr old daughter to my cousins house, and getting onto the main road, I hit is, and, it didn't go right away like is should. I was able to brake, and stop for the next opportunity, but decided to make a loop in the neighborhood, it seemed ok. I drove out about 30 miles, and, last night on the way home, getting OFF the highway about 8 miles from home, it stumbled coming down the off ramp.
I turned onto local roads, and really lost power (much like a bad fuel/fuel filter/biodiesel issue I had w/ my '02 GMC a couple of years ago) I have NOT RUN BIODIESEL since, and never in this car, but maybe in the future.
I pulled over; it really began to shudder/shake then died. I was apprehensive due to the now sick and sleeping 3yr old girl in the back, and my wife was unavailable to pick me up last night. But, someone was looking out for me. I started it up, it ran, hard, but, I drove it the rest of the way home.
Pulling into the neighborhood, I just made the turn about 1/2 mile from my house and it would not go, and finally gave me a MIL (Engine Light) and then said "Emissions Workshop"
I decided to leave it, and, (cold for TX), carry my daughter to bed, leaving the car over night.
I got it in the garage this afternoon, and, though I don't have VagCom (yet, it's coming for sure!) I do have a can tool for my computer that will read OBD-II and a connecting cable (which won't work w/ VagCom software, I’ve tried w/ the download).
I pulled out 2 codes
p0404 - O2 Sensor Signal Biased / Stuck RICH Bank 1 Sensor 1
And
p2196 - Powertrain - Exhaust Gas Recirculation Open Position Performance

Here's what I've done up to now.
I bought and replaced the Fuel Filter w/ a $26 unit from AutoZone (I know, questionable quality, but, I wanted to start there first) It really felt like a low fuel availability problem to me.
I drained the filter into a clear bottle, in case there was a lot of water in it, resulting in contaminated fuel. (Last tank was filled up at an unproven station - I'm pretty particular and had been using exclusively Chevron, but, was in a pinch and used Shell this time)
I tried to start again, after powercycling the ignition switch several times to 'fill' the fuel filter.
Same results, immediate start; smooth for 1-2 seconds, then shutters and dies.
I did remove the 'dual' hose fitting on the fuel filter again to see if there was fuel inside, it was not as full as the old one, and upon removing, there was enough pressure to 'pop' it out like a champagne bottle when I removed it. That didn't happen the first time so, I suspect there's AIR inside that's compressing.
This leads me to the lift pump, which, though most sounds in this car are still new to me (3 months) has begun to sound like my old Dodge Ram heater core when it became obstructed and you could hear fluid rushing in like water running.
If I let it sit for 10 minutes and turn the key, I hear that slush and rush of fuel, if I let it sit for 10 seconds, I don't hear that after the first cycle.
OK, so, I'm going outside right after this to fill the filter manually if necessary w/ fuel. Sometimes writing it out helps, but, I've got to believe the 'lift' pump can fill a fuel filter. We'll See, I'll repost if this changes the result.
By the way . . . when trying to start/run the car SMELLS very RICH and smoky out the tail pipe. I've never smelled 'rich' diesel before, but, I believe this is the smell. It almost smells like something's burning up, but, I'm not getting smoke anywhere but out the tail pipe.
I've noticed that there is a 'beeeeeeep' or whine that comes from under the hood after the key is turned off for about 3-5 seconds. It's coming from an assembly connected to the intake manifold, with a black cover. The cover, when removed, exposes 2 electrodes, and inside there is apparently an electric motor which actuates a plunger. I think this is the 'anti shudder' valve? Previously actuated by vacuum on older models. I also believe this particular vehicle had a recall for that as it caused 'surge' and 'stumble', right?
I need to dig out those dealer records and see if the recall was done; likewise, I'll call the dealer tomorrow and give them the VIN and see if it's shows as having been completed.

I'm a little lost as what to do next, if filling the fuel filter w/ diesel doesn't do it, since I'm VAGCOM-less for now.
Dumb Questions -
1. What would you (all) Recommend
2. Is there really an O2 Sensor on the vehicle, where is it and can I trouble shoot based on voltage?
3. I need help w/ EGR, I don't know if that's an issue here, but, I'm wondering if it's possible that this valve is stuck, causing basically a restriction in the exhaust, trying to recirculate too much resulting in too much backpressure and killing engine. Where is the valve on this engine, and what's the 'troubleshooting' procedure?
4. Anyone know if I can use a ProScan Universal OBD-II Scan Tool w/USB Interface cable w/ VAGCOM Software (myscantool.com) I use this w/ other vehicles, and uses a software as well, but basically connects the OBD-II port to a USB port w/ a little box in the middle that shows RX TX for both ends of the cable.
Thanks for all the help you have all been just through research; I appreciate anyone’s advice, even if it's a guess out of the box.
