I don't know how to say this without sounding like a jerk, but I don't know if those are useful.

Yesterday was a very quiet day. We're down to 9.7 QPD. Time to break out some questions from the sandbox, methinks
On a more positive note, Area 51 indicates 30k+ visitors every day. We're growing

Q: What is that sound?

KlaymenDKI have a 2004 VW Golf Variant. There's no problem, I'm just curious. Just after I have opened the driver's side door, a small motor runs for about one second, then stops. This also happens if I stay seated after stopping the car, and then open the door after some time has passed. I am certain t...

so whenever you get something out of the car your Fuel pump works?
non sense.
 
@Anarach Yes it does
 
what made vw come up with that design i wonder
 
It might seem strange, but then VW appears to have a different design philosophy
Their fuel rail pressure is much higher than other manufacturers, for example
 
hmmm
 
@Zaid ... what is VW fuel rail pressure normally?
 
9:57 AM
@Paulster2 : Trying to find where I read it
 
@Zaid - I'm not readily finding it.
 
I have a couple of books at my desk here.. trying to rifle through them but I'm struggling to recollect
 
@Zaid - And are you talking about the common rail or the high pressure fuel rail?
Or am I just talking out my butt?
 
Umm, is there a difference?
 
Probably not.
And assuming you just filed that under "who cares"?
lol
 
10:07 AM
Lol, because the fuel rail is high pressure, right?
I presume the 'common' is because it's shared by all cylinders
 
You are right. I'm not awake, so I'll claim ignorance on that bit alone.
Do most VAG fuel systems have two fuel pumps?
low/high pressure?
 
Don't think so
Grunt. Can't find it
@Paulster2 Although I'm seeing a lot of HPFP acronyms, so you may be onto something
@Paulster2 : There's a YT video which shows 58 psi
 
10:30 AM
@Zaid - I think most of the GM vehicles have been running around 60psi for a while now.
 
@Paulster2 : Why come to think of it, yes, you're right
 
I'm not sure if the new direct injected GM engines have a fuel pump which does the HP needs, or if it's done through the injector itself ...
 
Ze Germans operate a little lower
Around 36 - 45 psi
@Paulster2 : Questions like those are easy to answer with the Bosch Automotive Handbook in front of you :)
 
lol
I would imagine so ... cheater
 
Shall I quote it here?
"Compared with injecting fuel into the intake manifold, there is only a limitied time window available for injecting fuel directly into the combustion chamber. Mixture formation is therefore more important and in the case of direct injection, fuel must be injected at a pressure up to 50 times greater than is the case with manifold injection."
That's just a teaser for you :)
