MAS Air Flow Sensor

Filed under: Uncategorized — admin @ 12:44 pm

A week ago I put up a post about my "check engine light" coming on  in my
2000 Golf.
Turned out to be the MAS air flow sensor.  Is this a reasonable problem?
About what should it have cost to replace?  Does VW have a list that the
dealer go by for repairs?

I feel so helpless about these things.  I don’t know what a MAS sensor it,
let alone if it actually need to be replaced, was replaced, or charged
fairly.

    I just replaced the MAF Sensor on my 1999 Golf IV about a month ago.
    It was replaced once before by the original owner (I bought the car in
    August of 2002), and now once by me.  I had to pay for it out of
    pocket since the car is out of warranty and the previous repair was
    done over a year ago.  However from what I have read the part is known
    to be faulty – so the 1st replacement may have been faulty, hopefully
    the new one I just got is not.

    In total, it cost me $170 USD (before tax) for the part and labor.  I
    think all dealers can do this repair.

    Basically, it controls the mixture of gas and air being sent into the
    engine.  When it starts to go the engine is usually getting too much
    gas – aka running richly.  It is something that needs to be fixed, but
    not a super urgent thing.

    I heard that it is easy enough to change yourself (just a plug you
    remove and then pop the new one in(?)) – the part itself is between
    60-80$.  But I don’t really know much about cars either, and due to
    not having a Bentley manual handy, I just let the dealer do it.  Or
    for all I know they just disconnected the sensor and screwed me over.
    Bastards.  :o)

  2. What engine do you have in your Golf?  TDI, 1.8T, VR6, 2.0L?

    The 2.0L MAF’s are $40 or so…the other MAF’s are rather expensive — in
    the $300-$400 range if you buy from dealer.

    There are online sources which can sell them cheaper, ie: http://www.vwparts.com
    and others.  If you have a TDI, i think that someone is selling, on
    http://www.tdiclub.com, OEM replacement MAF’s for around $180 which is a
    substantial discount.

    And yes…the MAFs in VW’s tend to be problematic and prone to failure.
    There are a few workarounds available — look for posts entitled, ‘Pierberg
    MAF’s’ on tdiclub.com’s forums if you want some examples of workarounds that
    are available.

    It is the 1.8T, so I guess the price wasn’t so bad after all, thanks.

  4. MAF sensor failure is pretty common in VWs, though many people never
    have the problem. You may be covered under emission components
    warranty, depending on the state you live in.

    Any idea about NY and a 2000 Golf?

  6. Your owner’s manual should have an emissions warranty section
    explaining what’s covered and for how long.

    Thanks, it does.  Two years; oh well.

  8. I’d read that section again.  Emissions equipment usually has a 60 to 80
    thousand mile warranty by federal law.  Most people dont know this, and I’m
    sure the de(ste)alers arent going to go around broadcasting it since these
    parts are not cheap.  IF it IS covered under an emissions law (I honestly
    dont see why it would be, but it could be), then give ti a shot at getting a
    new one.  the worst they could say is no.

  9. I think the emissions equipment is also covered for about seven years,
    so it’s worth looking into it further.

    Comment by admin — July 29, 2010 @ 12:44 pm

  10. I think that’s only in California! A lot of items that one would think is an
    emission warranty isn’t anymore. But if the car is under 3 years old and
    36,000 miles VW may pickup the repair or maybe just the parts.

  11. But many states, like Mass. where I live, follow California’s lead and
    enforce the same regs. Call you state envt’l agency.

  12. Since you 1.8T is probably AWD engine (150hp)
    You should be able to use 2.0 MAF which is a lot cheaper (~$40).
    2.0 has a different plastic housing, but the internals are the same.
    Just move the internals from the 2.0 housing into yours.

    It will cost you $40 and 20 min of work instead of $180 for parts or
    $350 at a dealer.

    VW knows about this and asks for a 2.0 VIN when people are ordering
    2.0 MAFs.
    A VIN from any 2.0 at a parking lot comes handy here…

    Good luck.

  13. It may very well work but consider this. All 2.0L engines use all 5 wires on
    the MAF but most 1.8T’s only use 4 wires. Will it work, and work
    correctly… maybe! But I would not take the gamble of using a part which is
    not designed for the car. After all that’s why they have different part
    numbers.

    I just replaced mine last week. (99.5 2.0 Jetta) Dealer said $180 P&L.
    $60 for just the part. Needless to say I just bought the part. Took
    like 20 minutes to install, including the time spent trying to find
    my bigass Channel-Locks to squeeze that compression ring loose. I had
    to drive it a few times before the computer was satisfied enough with
    the readings to extinguish the Check Engine light.

  15. Did you know that the connector that goes to the MAF also should be replaced
    to prevent reoccurring problems!

  16. Glad it worked.

    I own a ’94 GTi, and I suspect the MAF going faulty, the car is very
    slow and it has allways had good maintenance.

    I’ve read a few threads about the MAF for the A4 2.0 beeing cheaper
    now.
    The MAF for a A4 2.0 is 80 bucks, for my ’94 ABA 2,0 is 280 bucks.
    Shouldn’t they work in either car?
    Has anyone tried this out?
    Maybe the housing is different, but it is possible to adapt the new
    sensor to the old housing.

    You mean the electrical connector? Looked okay to me. I even sprayed it
    with some contact cleaner to make sure it was clean.

    Guess I’ll just have to take my chances.
