question for tomj2 by krzyss

Have you changed tires?
What about air filter?
Tire pressure?
Wheel bearings?
Stuck caliper?
Stuck hand brake?
 
I think I run out of ideas.

PS One more: different oil?

No to all of the above. VW checked it over. I figure that as a dealer, they were dying to find something wrong...

Sludge question by lisava

So if there is a Passat that did have some sludge issues at 45k miles and the dealer found oil output was low and replaced the oil pump, assuming from here on out all future oil changes will be done in a timely manner with appropriate synthetic oil, any reason to be concerned about the engine's future?

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!
