  2. 2002 4 motion brake booster vacuum pump not working

    Volkswagen Passat B5 Discussion
    I checked the pump unplugged with 12 v and it runs fine. Relay 373 in the 13 relay box and its' fuse are fine. Is there a module for the pump somewhere that could be bad? if anyone out there could send me a wiring diagram of the pump and its control would be great.

  5. W8 Fuel pump?

    Volkswagen Passat B5 Discussion
    So I picked up a W8 for crazy cheap and it needs a fuel pump but all anyone seems to sell is the entire assembly. Can you not swap out just the pump? ECS tuning has a ton of pump options but I asked them about using them in the stock fuel setup and they said they are for custom fueling...
  6. Power steering pump & fluid

    Volkswagen Passat B5 Discussion
    Starting to hear a whining noise from the PS pump when I turn the wheels end to end. Gonna check the fluid first to see if it is at the proper level. What type of fluid should I buy just in case I need to top it off? Just regular PS fluid or does VW have some special grade that I need t use?
  7. water pump belt installation

    Volkswagen Passat B5 Discussion
    98 1.8. Replaced thermostat and now there is a leak. I will dig into that later. Real question is regarding the water pump belt. Car continued to overheat as I drove it home from work (where I did the thermo change in the parking deck). Shut off car and rolled into a convenient parking lot and...
  8. 2002 GLX 4Mo Wagon Fuel Pump Location

    Volkswagen Passat B5 Discussion
    Car turns over but won't start after running fine the day before, so I figured the 1st thing I'd check is that the fuel pump is getting power. Except I'm not seeing what I see in every YouTube video and other posts on this forum. There should be an access cover for it behind the passenger side...

  11. Don't underestimate how long a water pump change takes

    Volkswagen Passat B5 Discussion
    Our son drove in from the Phoenix area for Thanksgiving, in the old '98 wagon which had a dripping water pump. He had an Air Force buddy with him, so I didn't feel right pushing too much to start on the car. Then another Air Force guy from their basic training days shows up and stayed over...

  13. Secondary air pump not activating

    Volkswagen Passat B5 Discussion
    I recently changed my secondary air pump after the old one whined and eventually stopped working altogether. The new pump does not kick in when I start the car with a cold engine. The pump works when hooked to an external battery. The relay (373) seems to be fine, with no resistance between...
  14. Fuel pump electrical connections - which is which?

    Volkswagen Passat B5 Discussion
    I'm changing the fuel pump on a 2002 Passat GLS 4Motion Wagon 6 Cylinder. There are 2 electrical connections that I foolishly didn't take a picture of before taking the old pump out, and I'm not sure which connection goes where. There's a black and orange (probably used to be white/clear)...

    Hey all, I have 2009 VW Passat 2.0 TSI with 130,000 miles. Couple of weeks ago I went to a dealership to replace a fuel pump control module (nothing bad with it, just to perform the recall). The very same day I noticed that my car started consuming a lot more gas than it used to. My combined...

    Volkswagen Passat B5 Discussion
    Hi everyone, My car, 2005 Passat GLX 4Motion 30V wagon, is garaged when at home, but sits in the sun when I'm parked at work. Recently it's been in the mid-upper 90s, so despite a windshield sun shade, the car is fairly hot when I get in to go home. Last week, it died rather suddenly about 3...

  18. Water Pump Debate: Plastic oe metal impeller?

    Volkswagen Passat B5 Discussion
    04 1.8t AWM Recently I replaced the coolant flange and temp sensor. Afterwards, a problem arose that had only happened once previously. It would overheat while driving, but stable at idle. My first thought was air bubble, because it wasn't overheating at idle. Bled the coolant at the heater...
