    Simple really, with it being a common problem with A3/S3 engines, have you had to changed the MAF(Airflow) sensor on your car?

    not yet, not even after 5 years.

    Saying that, its on the list to do, together with DV, and coolant temperature sensor. None are displaying any problems so far though.

    Poor running, like uneven power delivery, **** fuel consumption and it feels like the power is being held back under full throttle!
    It's very noticeable on petrol engines, diesel cars seem to just run lower power when the MAF goes.

    i replaced mine but found out later i was toooo quick jumping to conclusions...poor running wasnt due to maf...but rather a leaking head gasket and a cracked cylinder head ;( but they are common on vw/audi's

    Around £80 exchange with your old one at your local stealer, or £55 for a new sensor part from a local motor factors like GSF or ECP. Most people think that the factory £80 one is the best option for quality and longivity(sp?)

    Having worked for VW in the past Ive seen loads of the replacement sensors fail

    Cant remember the number but last time I spoke to my mates at the dealers they said that its in line next for being bought down inline with the other ones in the range that are £60 for the unit and actually no longer and exchange

    Oh and I found about 4 reciepts for them with my cars when I got it lol

    pull the plug off the MAF, that'll cause the ECU to use a set of pre-programmed values instead of the MAF signal, if it runs better it's the MAF at fault

    Would be interesting to find out also how many people who have had one fail, Whether or not they have uprated filter/cone etc????? (not hi-jacking I just think we would see a interesting set of results!!)

    "Induction" kit type filters that bolt onto the MAF seem to have caused alot of trouble when I worked for the dealers, had people replacing them all the time, guess its to do with flow ratios etc

    My maf is working fine however i would recommend giving it a clean. I found a guide on here somewhere, failrly straight forward anyway you just need a anti tamper torx bit to remove the sensor from the housing. Bought a can of contact cleaner from maplins for £3.99 gave it a good blast was suprised how much muck comes off despite a new air filter in place. I'm hoping this will if anything extend the life of mine.

    You have to becareful with cleaning the MAF as the element in then is so delicate, blasting them with a cleaner is not the best method, spraying towards the element and letting the chemicals do it's job is ok, but don aim the spray directly at full force towards it, as that can damage it.

    No, it's 61.29%(at the time of posting) of people who are still running the original MAF sensor without changing yet.

    I get poor fuel consumption. Around 28-30mpg. And its only a 1.6. I've had the thermostat replaced, temp sender replaced, throttle body cleaned, but the fuel consumption is still poor. Could this be the issue?
