    I have in front of me a brand new maf sensor for a vag 1.8, the part number is 06A 906 461L. I don't know which model 1.8 it is from but the housing is a little smaller in diameter.
    So I took the sensor out and found out the bosch number on the sensor is F 00C 2G2 049. That's the same number as the S3 sensor.
    Think this could be a mistake from the factory?

    Its smaller than the S3 maf housing, this one is 70mm dia.
    Had a quick search and it seams to be from a gti, beetle turbo, A4 quattro.

    Would all the 1.8t use the same sensor inside different size housings?
    I also notice that these sensors have 5 pins but my S3 maf sensor plug only has 4 pins in it, one is empty. So I check the wire harness and there is only 4 wires. Hope this is normal.

    Do they still offer the exchange service on MAF`s at the stealers? and if so what does it end up costing if you give your old one back?

    As i think i could do with swapping mine out for a new one at some point as i believe mine is still on the original and could be getting a little tired.

    Cheers for that guys,

    for £40 (after the exchange) i think i will do it cos after i cleaned mine my MPG has improved which makes me think its a bit old and tired so will sort one out i think.

    Will give the stealers a bell later on.

    Sorry mate, may not have been clear, but I spent £103.20 for the MAF- then when I take my old MAF back I'll get £30 credited which is the surcharge cost- so will cost £73.20 at the end of it.....not £40.

    seems someone else has found the F 00C 2G2 049 S2 sensor in the 06a 906 461 L MAF (bosch number 0 280 218 063)

    Please give credit where credit is due

    Might be worth investigating if this could be a cheaper option buy removing the MAF SENSOR and fitting it to the S3 MAF housing.

    Next time I'm at the scrappy, I will see if they have any.


    FYI - S3 AMK / BAM
    MAF sensor+housing part number is 06A 906 461 M or MX ( Bosch part number is 0 280 218 065)
    MAF sensor only part number is F 00C 2G2 049

    Don't we know already that the 06A 906 461 L , have the 00C 2G2 049 sensor? (which is the sensor used for wideband S3)

    I might have mis-understood your post.

    I was going to buy a 06A 906 461 L part and fit its sensor to my AMK S3. This will set me around 125$ instead of 210$

    well it needs to be tested to see if this works.
    in theory it should work since it was the same Bosch number.

    buy one and let us know :icon_thumright:

    Reporting back: It didn't work. The Maf i ordered is bosch part number 0280218063. Supposed to have the same sensor as our S3/TT 225 ones.

    First Picture my original maf sensor

    [​IMG]

    Second sensor is from the new maf

    [​IMG]

    After I switched the sensors i got an error on VCDS about the maf being maxxed out, car runned lean
