Passat (B5) :: CEL For N80 Valve Could Cause Bad Mileage?
My V6 4Motion Passat has a CEL for an N80 valve... tried cleaning, didn't do anything. But its only getting 400-430 kms to the tank, even for winter that's pretty bad for 95% highway driving.
Could that cause bad fuel mileage?
Passat (B6) :: Will A Bad DV Valve Always Throw A Code?
Just wondering if I will know via a check engine light if when my Diverter valve may act up. I don't really want to add a boost gauge if I can let the onboard diagnostics do the work for me. So if I loose boost will I know?

View 3 RepliesPassat (B5) :: Secondary Air System Valve Replaced / CEL Came On
I've had my 2000 V6 Passat in for service three times with Secondary Air System issues - the dealer said that the whole thing needed replacement. The indy shop identified a couple of things to repair but said total replacement was unnecessary. A secondary airs system valve has been replaced twice (same one both times). Check engine always comes on within a day - we took it to another dealer for their opinion and again. Said that I need to replace the valve (third time!).
View 2 RepliesPassat (B6) :: 07 - Pressure Regulating Valve Failure
Our 2007 Passat 2.0T had the 30K service and the fuel pressure sensor and pressure regulating valve (PCV valve) recalls done several months ago. Several weeks ago the check engine light came on so we took it in to the dealer yesterday. By the way, the car also felt subtly sluggish, had a slightly unstable idle and sometimes seemed to "stick" in gear on deceleration (ie, not shift down normally).
Here are all the DTC codes that were stored:
P0300, P0301, P0302, P0303, P0304, P0507, P2187, P2279, P3138, 02635
The service adviser said the problem was that the recall valves that VW sent them were no good (I think he said it was the -F valve) and that they now have an updated valve.
The new part number is 06F-129-101-K
By the way, our Passat is driven "conservatively," ie, no high boost levels or anything else that would stress the PCV valve.

Passat (B5) :: 1999 - Ticking In Valve Train
99 Passat 1.8 Turbo 4 cyl. Noticing a ticking in the valve train. Louder @ cold start. Can't hear it on acceleration, just when sitting. Sometimes it won't do it at all. But most recently it's constant. The other morning I cranked on and the CEL came on.
Took it to mechanic, he let it set for while to cool down, restarted and the CEL was off (hasn't come back on), he could hear the ticking, thought maybe the timing belt needs to be replaced or adjusted, the 02 sensor or possibly week lifters?????
July 06' VW did a "desludge" (for free!) and replace all parts having to do w/ oil and filled w/ synthetic. So that's not the problem. My mechanic isn't familiar with VW valve trains, belts, lifters, heads etc. He's done a great job on everything else, but acts like he's really scared to open this can of worms.

I took it to the stealership to get the alternator and some vac. lines replaced all under an extended warranty. They informed me that both valve cover gaskets and right side cam adjuster gaskets are leaking. By no means am I a mechanic or close to but I am trying to get this stuff done as cheap as possible so I am going to try to tackle this myself.

It only happens sometimes, but definitely everyday. I have an 06 Passat 1.8T and when i'm accelerating and it shifts gears from 1 to 2 it sounds like i have a really bad blow off valve, yet i don't. I can't see anything noticeable under the hood. I am thinking its the turbo inlet pipe.

So, weird smell that I thought was burning plastic or rubber is actually hot oil leaking from the valve cover and tensioner gaskets.
My car is nearly 8 years old (2003), and has about 70K. Should I go ahead and buy a timing belt kit and replace all that stuff at the same time?
Passat (B5) :: Check Engine Light On - Combination Valve?
I brought my 2004 Passat 1.8 in for check engine light-- After checking several things and test driving the car they said the finally found the problem-- the "combinations valve" I searched the forum and below was all I found this under that word combo-- is that the only "combination valve"? This is not something I've heard about before-- are they just saying perhaps 2 different valves?

Passat (B6) :: CEL On / Code P0299 - How To Replace The Diverter Valve
The CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:
000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached
The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.

Passat (B5) :: Low Oil Pressure - Valve Rattle / Rough Idle
I Have a 2000 Passat 30 valve v6. I got a low oil pressure message figured I could make it to the store for some oil. Well I turn a corner and heard a valve rattle and the car started to idle rough. I was two quarts low but the noise and the rough idle still exist. In neutral the noise is not noticeable. Driving the noise is only noticeable at high RPM. The car doesn't smoke and otherwise runs fine.
View 1 RepliesPassat (B6) :: Breather Block Off - Check Valve Is Broken?
I have the bsh pcv fix and since the valve in the breather was making that noise, I busted the valve out.
Now I think I have a small boost leak somewhere and would like to pressurize the system but what do I use to block off the breather tube now that the check valve is gone?
I hear a little horn like toot sound around 5psi. Almost like letting a balloon full of air fly around letting the air out. How to describe it. Pretty sure it's a leak.
