I originally posted this in the "What did you do to your Passat today?" thread, but I thought this specific question might get more visibility with its own topic: After I replaced all four O2 sensor last week, there were a couple of DTCs that popped up after the emissions learn cycle: P3296 and...

Is there a designation ID for this car? I see B5, B6, B7 etc listed in all the topics but unable to figure out which one is for my car? Hopefully when someone replies to let me know the correct area to post my question, I'm going to post it here for now. I have 4 problems with this vehicle (for...

Hey guys...Miss me? 2002 B5 V6 GLX 4mo. About a month ago I replaced my ECU because it was fried and everything has been running relatively smooth since then until about 5 days ago. It survived the 5 hour road trip and has been getting me around time with no issues. Then one day I had to hit the...

I am getting the fault codes shown below. Could the Oxygen Sensor problem cause the cylinder misfires? I think I already have an extenders on the O2 sensors. The car seems to drive fine but when I come to a stop with the engine running, it idles very rough. This happens when the car is fully...

Engine: V6 Mileage: 117k Synthetic oil, Removed Intake plastic cover and after market intake K&N 69-9756TFK. Replaced timing belt, serpentine belt and water pump. The car runs and idles great, I cleared the codes with obd2 plug in and traveled around 200 miles on the interstate, as soon as I...

Can anyone tell me what could be the problem as far as what O2 could be bad? I can give live readings if anyone can decipher those. Or if anyone has a tutorial on how to read these things that would be great also. Thanks for your help in advance So here is what I have as far as readings, faults...

Hello, this will be my first official post, but i am having a problem with my AUG 2001 passat 1.8t (B5) Passat, the original motor was replaced with a brand new VW OEM motor, after driving the car only a couple of miles it threw the "emmissions workshop" and the following codes at me: p0327...

I have a MAFS and an o2 sensor for an ATW engine. I bought them and ended up not needing them, so they are still in the box, brand new, never put on the car. The brand is REPLACEMENT. Looking to get ~$50 for MAFS ~$40 for o2 sensor. Don't be afraid to shoot me an offer...

I have a 2001.5 AWM VW Passat GLS 1.8T A day before I was going to do my smog my engine light came on! :banghead: So, I had a friend hook up his code reader and from my research I found that my O2 sensor is failing. My question is how do I know which of the two sensors is failing?? (the code...

I have read many threads on this code and followed the advice, but still have the code. The car is '03 1.8T Passat GLS Wagon, all stock, with 84,000 miles. Recent fuel filter, air filter, had the coil replacements (recall). The idle is good and there are no noticeable performance issues...

Hey guys, I'm just new to this. I've browsed the site before many times. I own a 2002 Passat 1.8L T. recently, Winter, I've noticed if the car doesn't run for a period of time "overnight" when I turn it on again, the RPM run low unliike before. When it was normal, the RPM were just over 1RPM...

When I hook up vagcom and go to engine->readiness I get this screen: I have a second thread going about the secondary air system. Since that's a whole other can of worms, let's not talk about that here. I'm trying to make sense of the following screens about my post catalytic converter...

P0421 while i was online researching this error code this is what i found what does this mean? Basically this means that the oxygen sensor downstream of the catalytic converter on bank 1 is detecting that the converter is not working as efficiently as it should be (according to specs). It is...

Hello, everybody! I'd appreciate if someone can guide me... I recently cleaned throttle body and now car runs great: rough idle problems are gone, but now CEL pops up periodically. Sometimes I get P0134 code only, other times different combination of codes below: P1476 - EVAP Emission Control...
