Title: wow, I'm another newbie, there's a lot here!
Post by: jamathe on February 09, 2006, 12:25:32 PM
I just got myself a 2004 VW Jetta GLI and I was told about this group from my coworker Dave Kirstein.  He's got a 2002 VW GTI 337.  We basically have the same cars, so I'm glad I know someone that can help me with any problems with the car.  I'll probably join him when you all have a get-together or garage day.

Nice you finally posted, I guess my pestering finally paid off.  Jim's car is very nice.  It is a Black Magic beauty, do not let the pics fool you this thing is gorgeous in the sun.  The interior as  black on black and is sweet looking.  The only thing that he needs off the bat is to get the BOV that the last owner left on (when will the madness end!).  The car is solid and quiet, no squeaks and creaks.  I have ridden in it with Jim and I can tell he really enjoys the "VROOM" factor.  I have already asked him a few times what he is going to mod first...it is only a matter of time Jim, only a matter of time!!!  :lol:

I think Megan would tell you that she is well aware that I need special help...and have so for a long time.

And Mike, it's a BOV...Blow Off Valve.

Ah, "B" OV.  Got it.  I feel so inadequate now with my NA motor.....

I believe that was called a turbo bypass valve on my Saab 900t....  Doesn't the motor still need a bypass valve?  You can't simply adjust them?  That's how it worked with the snaab....

Yes, the turbocharged VW engines come with a bypass valve, but some folks replace it with a Blow Off Valve

The difference is the Bypass Valve will recirculate the unused pressure through the system, in fact the ECU counts on it. So when you throw a BOV in the works in blows off that excess pressure to the atmosphere and makes a neato sound.

However, on the 1.8T it can cause CELs and other issues because the ECU gets mad.

What Jay said.  Diverter Valve (DV) is the common term used to reference the bypass valve, or recirculation valve.
Title: Re: wow, I'm another newbie, there's a lot here!
Post by: Lila on February 10, 2006, 09:47:26 AM
Ok, so a BOV is there to make a cool noise?  Does it do anything useful?  Why "dump" pressure instead of recirculating it?
Title: Re: wow, I'm another newbie, there's a lot here!
Post by: ianacole on February 10, 2006, 09:50:23 AM
Because it makes a cool noise... :roll: Honestly, that is the only reason to do a BOV.  Some units are now providing both functions, recirculation and atmosphere release, because of the issues that VW (and I suspect other manufacturers) have with BOVs and CELs.

ian - please don't do a BOV to be cool and get the cool kid noise.. Don't forget about your kids.. Do you want them to grow up knowing that daddy bought a BOV so he could sound cool? :D

wooooo.. woooooooo..

you could get the bub rub approved WOOO, WOOO tips.

It's my last opportunity lest they think I'm a dork for the rest of my life...which, regardless of what I do, will be the result.  But at least the kid in the Honda next to me will think I might be cool, at least until I roll down the window and he sees an old man and hears Dvorak.  Oh, well, I might as well accept my fate and just blow him off the line in my quiet, old man dork, way.

Well the idea behind dumping the excess pressure is less turbo wear. Really though, there are just show.

I got ina  discussion over on the tex in the B6 forum I believe about a BOV for the 2.0T. Basically the usual everyone jumping on it. It is switchable so you can go from full recirc like a bypass valve to partial blow off or full blow off.

No performance gain, just a show off, and a $180 part.

On a side note, the new bypass valve system on the 2.0T FSI is really neat.

I think the BOV would be cool if you got some pulsing neon lights to go underneath your car...

In either case, welcome to the club!

P.S.: POV's are bannable offenses here too.

A CEL stands for what?
Title: Re: wow, I'm another newbie, there's a lot here!
Post by: ianacole on February 10, 2006, 01:32:42 PM
Check Engine Light, also referred to as a MIL (Malfunction Indicator Lamp).
Title: Re: wow, I'm another newbie, there's a lot here!
Post by: Nickle on February 10, 2006, 01:40:44 PM
LOL.  I did know that.  Pardon the blond moment.

So, here is my understanding of why our friendly little CEL shows his beautiful yellow color.  The nearly instantaneous pressure drop caused by a BOV induces a fuel spike.  The engine picks that up from the O2 sensors, and tells the engine something isn't right.  This supposedly has something to do with the MAF located before the turbo, correct?  I don't know any of that for a fact.  It's stuff I’ve pieced together after reading numerous VAG forums.  I guess I'm looking for an explanation of why our engines respond so poorly to BOV's.  Not that I'm thinking about getting one, I have a 710N that works fine for me.  I'm just a Mechanical Engineering student with way too much curiosity.  ;)
Title: Re: wow, I'm another newbie, there's a lot here!
Post by: ianacole on February 10, 2006, 01:46:18 PM
I actually think it's because the engine is morally opposed to the BOV.  In this instance, CEL stands for Contraband Equipment - Loser. :lol:

Actually, I don't know the technicals of it.  It could have something to do with the fact that once recirculation is engaged, the system is expecting a certain amount of pressure modulation based on that.  When purging to atmosphere, the amount of recirculation is reduced, thereby confusing the system.  On the GTI, the DV is between the MAF and the turbo.

Audi's study manual on the design for the 2.7T has the following to say about the diverter valve:

"The pressure limiting valve and the non-return
valve control the return of these vapours and
gases to the engine, depending on the intake
The pressure limiting valve limits the vacuum
in the crankcase. If the vacuum in the
crankcase exceeds a defined value, the
diaphragm is drawn over the connection
against the force of the spring and closes the
connection. The valve is designed in such a
way that it allows a small quantity to pass
through when closed. This prevents the engine
oil being drawn into the intake tract and has no
adverse effects on engine breathing."

Sweet.  That helps.  So really without a slight intake pressure, oil will enter the intake system.  Is that a correct statement?

that is how I read it, and that could cause fouling of the o2 sensors which would set off the CEL.
