  1. Sudden drastic drop of MPG

    Volkswagen Passat B5 Discussion
    I got a sudden drastic drop of MPG in the past 2 days. The car does not give more than 15 MPG in normal city drive while it used to be between 24 and 26. There are no fault codes. The air filter is clean, spark plugs were changed 2 years ago and coils are new. MAF senor was changed last year...

    Volkswagen Passat B5 Discussion

  5. Bad MPG when Climatronic is on (air OR heat)/Coolant Leak

    Volkswagen Passat B5 Discussion
    I noticed my MPG drops quite a bit when my climatronic unit is turned on regardless of if it is heat or air conditioning. Is there a part that may be malfunctioning that is causing this, or is it just how it is supposed to be? Other than the occasional P0421 that comes and then goes for a while...
  6. European car in USA MPG US Gallons or 'Imperial' Gallons?

    Volkswagen Passat B5 Discussion
    So, a European car in the USA, shows MPG etc. Is that in miles per US gallon or per Imperial gallons? If capacity is 62 litres, then it's 13.63 UK (Imperial) Gallons and 16.38 US (Gallons). Fuel Economy site shows combined mpg of 20 (combined) and 25 (highway) so i take it that is US mpg...

  8. Bad MPG issue

    Volkswagen Passat B5 Discussion
    I looked through many forums but couldn't find my specific problem. I never got too good MPG since shortly after I purchased the car (99 Passat 1.8T AEB), however after just changing the oil, valve cover gasket, spark plugs, control arms and springs, the MPG is still just as bad / worse. What...

    Anything Auto
    18 vs 53 MPG. On the left you will see the city MPG of the Passat. On the right you will see the city MPG of the Prius. I am now a confirmed hyper-miler. Know anybody who needs a set of B5 Bentley manuals?

    Volkswagen Passat B6 Discussion
    A few months ago I purchased a 2007 Passat B6 2.0t FSI with about 140k on the odometer. I love driving the car and love all the amenities that come with it. The only problem that I have had, is the gas mileage is terrible. I have been driving it for the past 3 months, probably around 1500 miles...

  13. Why am I getting better MPG driving in my town than the parkway?

    Volkswagen Passat B5 Discussion
    I just had my fuel filter and air filter replaced so now my mpg is actually going up in general, but it is still not making sense that I was getting better mpg driving at speeds from 25-50 in my town than 70-77 on the parkway without stopping. I'm absolutely stumped. I use cruise control when I...

    Volkswagen Passat B5 Discussion
    Lately ive been getting horrible gas mileage. I get somewhere between 200-250 miles per tank. I recently did plugs.

  20. 2004 Passat MPG

    Volkswagen Passat B5 Discussion
    Since the recent purchase of my 2005 STi, there is no reason for me to drive my 1.8t passat hard anymore. That being said, I am trying to drive more fuel efficiently, I still find it hard to get much over 30mpg on average, a lot of highway driving, not much stop and go. All that I have done...
