O2 sensors going bad?
Thermostat not fully closing?
Vacuum leak somewhere?
 
At some point, all these can occur and not show up on the OBD2.

Those are reasonable questions. May be worth looking into although I would hope VW would have picked them up. Would a bad O2 sensor cause it to fail an emissions test? It passsed a few months back.

What I understand is that the O2 sensors deteriorate. They slowly fail, versus an "on-off" issue. They could still be within the range of "acceptable" but not giving the most accurate signal. Hey, I'm just guessing!
 
BTW, the web is full of stories where one would have hoped that "VW would have picked them up. Personally, I think they rely too heavily on the "there's MIL, so all must be perfect" approach to troubleshooting.

I guess you have a point. Maybe I'll pursue that. Thanks

It's all guesswork from here. Good luck with it and please, please, please post back when you find the answer to your issue.

1999 Passat - Exhaust Intake snapped by divinity

OK.
 
So, i'm no mechanic, and it seems it's hard to find info online (vehicle manuals/diagrams) that would help me become one.
 
First:
Does anyone out there know where i could get a bootleg FREE copy of the 1999 Volkswagen Passat 1.8 turbo REPAIR MANUAL?
 
Second:
While i was driving my Passat there was a blow-out of my exahust intake manifold (where the exhaust attaches to the engine). So, naturally, of course my car sounds very loud because of the disconnection. Does anyone know what the exhaust (the part under the hood, near the engine - not under the car near the Cat) is made out of - cast iron ??
I have thought of welding it back, but am leaning towards a replacement of the part.
 
Any feedback/knowledge sharing is appreciated!! Thanks for your time!

Wait...what? The "exhaust intake manifold?" Which one - exhaust or intake? They're mutually exclusive. Need more info to help you.
 
If you were to google "Passat Etka" you might find something that woudl help you.

One page maintenance chart? by passatstuck
Oct 11, 2009 (7:14 pm)

I've got a 2003 Passat 4 motion wagon. v6.
There isn't any handy dandy one page chart available. I must have spent two hours w. the manual and on-line also. I called the VW dept. that's responsible for manuals, and they don't have any such thing.
 
Two Questions:
1. Has anyone compiled a chart?
2. Has anyone found maintenance info on severe conditions?
 
Exasperated and stuck w. my Passat.

VWoA's website has a feature where you can plug in your veicle info and it will generate the next maintenance required for your mileage. Once there, you can click on "View Complete Schedule" and it will show the entire schedule. It is not a severe serviceschedule, however.
