    Hi all,

    I've been experiencing some hesitation and bogging down under load from my s3 since i got it 3 weeks ago. In conjuction with this i have had intermittantly the abs and esp lights coming on the dashboard.

    Yesterday aswell as the lights i got the warning display and 3 beeps flashing on the dash "ABS fault go to dealer"... then today leaving work the car seemed to go into limp mode and i had no power.

    I decided to try unplugging the MAF to see if it would fix the hesitating - and it did! completely different car.

    The question is, a bit of research has shown me that the MAF frequently triggers the ABS/ESP due to them reading it for load data... What is the chances of me replacing the MAF and solving all my problems?


    and also where to buy a new MAF, as i see a lot of people have had issues with ECP recon units.


    Cheers!

    Yep, I think you've answered your own question! New maf should do the trick...

    the gsf one is only £45 ... so unsure if that's a bit cheap to be a good 'un?

    I should think the bosch one will be the premium part, which works out about £80 ish after you get the surcharge back.

    Fitted the nww MAF today... hesitation sorted. ABS Warning and 3 beeps still going... I tried disconnecting the battery but that didn't work..

    And still no fault codes (scanning with torque app and obd2 bluetooth)

    Any ideas?

    Torque App is no good, only reads OBDII related codes, not Manufacture specific which is what you need.
