Re: fuel pump (GMoney805)

mine just went at 33,500 - not quite 2.5 years old
is this a common problem w/ the 2.8v6? its the only other post i've found in the Passat B5 forum
i've only used 93oct, sometimes 91oct when i could find it (the car requires 91 or higher) never once have i put anything below 91 in it. not sure if that matters, just not happy w/ the situation.

i sincerely hope not. i'm only at around 27500, but i've never had any problems with my fuel pump in this car. (just tranny not wanting to go in 2nd gear) but if i do, i'll be mad b/c on my old truck i was replacing fuel pumps every 8 - 12 months

and that gets old fast!
 
Re: fuel pump (GMoney805)

You should run mid grade or premium, mid grade in the winter,
premium in the summer.
You dont HAVE to, the knock sensors will just retard the timing, which gives you less power and lower MPG.
Fuel pumps go by run time.
If you do hiway miles, a fuel pump can go 300,000 miles.
if you do lots of local driving, you might only get 90,000 miles
out of one.
They work just as hard at idle as at full throttle.
Running low or out of gas wears them fast, as the gas cools and
lubricates the motor and pump.
But even with abuse, the typical fuel pump lasts 100,000
miles easy.

I agree with you, Brett, but a few folks rejected my advice to try to keep one's gas tank above 1/4-full at all times. I always tell my wife I never want to see the little red gas pump warning light come on.

Brett, when would be an appropriate time/mileage to replace the fuel pump? I'm at 40k, and my dealer's recommended maintenance includes the fuel pump, which I think is a bit premature. Any thoughts when I should replace it?

Re: fuel pump (passaturge)

so far the dealer i went to is having problems finding a pump. he promised me he has one coming from another dealer 70 miles away today...
i am reading posts that there is a few others who have had this problem in the 30,000-35,000 range??? fuel pump should never go under 100k!!!!
does anyone have contact info for VW of North America? I'm definately writing them a letter as well as like NHTSB.
 
Re: fuel pump (GMoney805)

[re: premature fuel pump failures]
I've read that certain plated electrical components become intermittent from corrosion that is caused by our (US) high sulfur content fuel. The fix is supposedly changing the plating to gold in newer pumps. The problem has hit quite a few European automakers including BMW and MB. In Europe, their fuel (both gas and diesel) is low sulfur so the problem doesn't show up there.
 
Re: fuel pump (E36BMW)

My car started then stalled last night (at home), now it wont
start at all.
it cranks over fine, but that is it.
You guys jinxed me big time, as it sure seems like a fuel pump
problem.
Thats just crazy to have pump problems under 30,000 miles.
I got to dump this pig, first the evap system alarm, then the trans
in limp mode, now the car wont even run!

Well, at-least it happened at home. And your right, the pump should go over 100k. I had 185K (and 13 years) on my old Saab and it still had the original fuel pump. This problem smells of a cost cutting measure that went too far.
[edit]
Brett, what was the deal with the trans and the limp-home-mode? I missed the details on that one.

Re: fuel pump (E36BMW)

Well, it happened a few times a year ago, and I thought it might have been a weak battery from sitting all the time.
About a month ago, it started again, then did it no matter what, every
start had the alarm.
I think the problem was a relay or connection, the connectors in the right footwell were badly corroded, along with the trans ecu connections.
I now sometimes get the alarm, but very rarely.
But the car wont run.
I will check for fuel pump voltage and current tonight, if I have voltage and no current, I will pull the pump and see what is up.
Since I fooled with all the relays and connections, I am not 100%
positive its the actual pump, but it ran fine for a few days after
I did the connectors and so on.

...that's not right. A 2003 with corrosion on electrical connections *inside* the car in a protected environment.
 
Re: fuel pump (E36BMW)

Yes, and my drains are clear.
I found water in the trans ecu box.
The connectors were badly corroded, I had to scrape it off the pins.
Same with the connectors in the right kick panel.

i have a 2003 Passat. 21600 miles on it and had a fuel pump problem two weeks ago.
i was driving toward wisconsin dells and my car just lost power on the highway. no warning, no nothing. it just stalled. the problem --> corroded fuel pump wirings. i have the car for just less than 2 years and i have problems like this.
vw paid for everything since it's under warranty. nonetheless, it ruined my whole vacation. i live in chicago btw and i have to take another day off, drive 300 miles roundtrip, and pay $70 on gas (for the rental car and my car) to pick it up from the wisconsin dealership.

this will be my first and last time to own a vw. it's not reliable. http://****************.com/smile/emthdown.gif
 
Re: fuel pump (chicago03vw)

I looked at the car today, removed the trunk liner, the bung over the gas tank, and first thing i did was plug a 12 volt light into the fuel pump connector.
I got a nice bright light when turning the key on.
I measured the fuel pump resistance, open.
I took the cover off the gas tank and checked the wires inside, still open.
I pulled the connectors off the pump and had conductivity
on both wires.
The wires have crimp on connectors, they crimp on the wires, and the
wire and connectors looked fine.
I measured the pump connectors, and had conductivity.
I did not read the manual and broke the hose connection
off the pump, I then read the haynes and removed the pump.
The connections looked ok, so I also suspect the pump, no way
I am having things apart and not replacing the pump.
Now, to find a pump on the web....
Crap cars really, coil packs, fuel pumps, oil seals blowing out,
fuel gauge problems, oil sludge, evap alarms, air pump failures,
all the common faults these cars have.....
I have 11 days off and it starts with a dead car....

Good to hear you've got to the bottom line on this thing.
