    Ok so after abit of research ive decided to fit one but:

    1. Where do i get it from? Ive got a part number here but is it correct 034 906 283j!
    2. Is there any guides on fitting it, where it goes, what todo when it's fitted etc!

    Thanks

    The ECS N75 Race version is the same thing. You can get that from Awesome or any other ECS dealer. Rich_A3_Turbo might be able to help. Otherwise, any dealer should be able to get you one if you have the part number.

    Fitting is pretty simple as you just replace the current one and the piping and plug fit in the same places. Although you might need a few jubilee clips as the OEM clips are usually shagged once you get them off.

    The only difference ive noticed is the price, the ecs one is about £30 dearer i think.

    Where exactly is the n75 valve located? Anyone have any pics?

    i've literally jus fitted the N75 J valve in the past 10 mins as my car was lagging through the higher gears, well its stopped the lagging and its powering staright through....but, it feels like my car has gone back to standard. It was mapped the other week and the acceleration was excellent but now it feel as if the map has been removed.
    not sure whether the fault codes need clearing on Vagcom or what??

    its found coming off one of the branches on your turbo intake pipe, its a brown cylinder about the size of a cotton reel with a brass coloured casing. then it has another 2 small hoses coming off it aswell as a plug

    It slows the rate at which the turbo opens the wastegate.
    It increase the boost on average upto a extra 3-5psi and that equals more bhp and torque. That is right isnt it?

    make sure you fitted it the correct way around as it fits in reverse to the standard one there is a long pipe coming out one side and a short pipe the otherside make sure the long one goes in the same place the long one off the original was and the short where the short was, basically the plug has to go the other way around, the wiring may be a strech but i extended mine

    yeah they all go in the same place what i mean is you have to fit the valve the opposite way around not fit it in the other side of the engine bay lol, your standard valve's wiring would face to the left in this pic not the right

    This is slightly off topic but popped the engine bay today as the weather was scorching this afternoon (just been on arun so car was warm) and played with the n75 valve not knowing what it was, anyway got back in the car togo out later on and the abs light popped on, sh*t myself wondering what id done haha, had aread and found out its quite common for the abs light to come on due to is it speed senser or something, yet another thing to fix :keule:

    yeah so if its the wrong way around you will get your symptoms if you have it the correct way around then you have caused a fault when fitting check the wiring etc around the valce you could have broke one when doin the change, or its coinserdence that another fault has occured or failed due to the n75j
