2001 Volkswagen Passat Question: Mass air flow sensor permanently remove or remove for one month?

 

Question

So can I keep the MAF disconnected for two weeks straight without having any problems and expect the car to run comfortably?
i say this since to know if the mass air flow sensor is the problem we disconnect it and see if the car runs okay, since with the sensor disconnected, engine returns to its "Default" values.
Please let me know since i have to drive to boston in two days from new york.(4 hr drive - 250 miles)
thanks you so very much!!

    You can buy the sensor fairly cheap from the VW dealers.
    Which engine does it have? 1.8T or V-6?

    It will run, possibly your gas mileage will be off of the chart.
    Did you check if any vacuum hose are disconnected or leaking? What kind of codes where registered in the ECM? Do you use K&N filter?
    I'd try to clean the sensor first, CRC makes a good cleaner, and reset the adaptations - you can disconnect the battery for a while to do that and see what happens.
    Did you call VW directly? I thought they lowered the MAF sensor prices. For some certain models they where under $100 while the parts stores sold those for about $220. I don't remember the year/model though. Better if you call them, even if you want to repair it later.

    You are very welcome. I hope cleaning will fix it. Call the dealer too for the price.
    Anyway, have a good trip back to Boston.
