    Right i don't know how to put it and the correct way of explaining so will try my best


    ive been getting some strange surges, hesitations, and dv sounds

    i had a bailey recirc valve on

    when driving the car steady away there were what felt like surges and flat spots you would drive along build throught he revs all of a sudden flat spot and whoosh off
    also you can hear the dv going sssshhhhhhh and then chhhhhhh
    when driving aswell the dv would dump unexpectedly

    so was at our reginal meet on sat lads had alook under the bonnet
    said that the dv could be sticking and that the pipe that went from the dv to intercooler was kinked so do those

    so today i have banged a new standard dv on and new pipe, also done n249 bypass

    so took car out for a drive and still hesitant and flat spots, also the dv still going shhhhhhhhh and then chhhhh as building the revs

    also the traction light has come on today and staying on what could this be and could it be in relation

    ive ahd the car on vcds and no codes (this was before traction light cam on) so not sure if any codes have come on now as not near my mate fo vcds

    can anyone please help maybe shed some light on where the hell to look and go next really starting to get annoyed just want the thing right and drivine properly please

    Where abouts do you actually live drew? Is the pipe to the dv still kinked? Have you checked all the Pcv pipes under the inlet manifold and also all boost pipes as these would make your turbo spool sound louder and also give you flat spots? Matt

    Everything.

    Unplug the MAF, go for a drive, everything will be perfect then go straight to TPS and buy a genuine MAF.

    Would not do any harm. However I am sure if you unplug the may the car defaults to factory settings. Iirc I had to clear faults first before it ran better with the maf unplugged. If it is the maf go to tps, I got one from epc but still got wee issue when putting the foot down in 6th gear. Defo NO cheep ones from eBay!!!!Mark

    so best thing to do until I can get a maf is unplug the maf anf then clear the faults
    go get a new maf plug in and see what the score is then bud

    So I have done what was suggested and unplugged the MAF
    the car is certainly a lot lot smoother
    BUT the car still has a flat spot around the 3000 revs especially in 3rd and 4th, and still get the odd dv let off when im building through the revs
    is like im driving alon changing up through the gears and all of a sudden chhhhhhh the dv releases when I have foot on accelerator
    really puzzled
    I did how ever think of something I read and I pulled over and unplugged the N75 with this unplugged there was no flat spots atal
    so does this mean I need a New N75 if so what one do I go for
    Also I have noticed past day or so what sound like I can only describe as someone blwing on the tip of a bottle if you get me in the rear of the car only every so often when going up revs maybe lasts for 2 secs and then disappears then comes back anyone any idea on this aswell
    thanks much appreciated for any help and replies

    Yep, new N75 and MAF.

    Unlucky Kentucky.

    Replace the N75 first. Then if it requires further attention look to the Maf.

    N75: go with oem unless you are planning some sort of monster build
    TIP: can't help you there, never looked in to what tip is best for a ko3s
