    Ive heard a little bit about this and personaly dont intend to do it unless i get swayed with facts about it. Ive heard of people buying kits to do this job can you not just remove the top vaccume pipe from the egr (the one that stops the plunger opening to allow exhaust gasses through) and plug up the pipe or does the exhaust gas pressure force it open a little bit? As i dont see the point in fitting blanking plates etc when this could be done in about 5 seconds?

    Ive done it and its recommended..
    The delete mod took me all and all aprox an hour.. Had to get the metal thing out of the 90* bend pipe, to fit the delete part.. Vacuumhoses are blanked of with a bolt or similar..
    Buy You need to delete it in the ecu as Well or a fault will pop up..

    Pros are:
    Cleaner engine
    Better air intake (Carbon build-up in egr)
    Better combustion
    Faster (not much though) turbo spool
    Better milage

    Cons are:
    None

    But its highly recommended..
    At least get it turned off in ecu..
    And clean the egr( or replace it with delete now You have it off)

    Yours could look like this:

    Mines as clean as a whistle i made a thread its in diy sticky about turbo vanes fix and also cleaned my egr and inlet, i heard that only 2002+ cars bring the fault light on as 2001s egr arent connected to the ecu, which is what mine is, i still dont see the point in plates or a kit when 1 vaccume pipe can be removed and bunged to stop the exaust gasses getting into the inlet....

    In theory yes it could just work like that

    I put a plate in mine I made it so didn't cost me a penny and was in there anyway

    Mines a 2002 and isn't connected to the ecu so it was just a case of blank it and pull the hose

    Is there actuy any need in the plate thought if the plunger doesnt open to allow the gasses in with the vaccume pipe pulled and blocked?

    I would rather have some physical blanking plate rather then trust a valve that could be leaking

    Is there a step by step guide on how to do this mod?

    How can you check if your egr is connector to the ecu or not as approx £95 to turn the light off seems steep....

    I did this to mine, then put a new map on with the EGR deleted. On my last car as it was more power modified I had a full EGR delete on there, but after experiencing over run when a turbo failed I was never going to bother with a full delete as I'm not going for power with this.
    If these are the same as the VW's then general rule of thumb is 03 reg and before won't get a light, 53 reg is 50/50, and 04 reg onwards will get the dash light.

    I did this whilst changing the air filter as removing the air box give you more room to operate.

    Deleting the EGR to turbo pipe

    To do this you will need two blanking plates that are available from the likes of eGay, but if you work with steel, or like me your dad does then you can just knock some up out of 2mm stainless.
    If you plan on making them yourself then order a new gasket for the EGR side of the pipe as this one is more likely to get damaged when removing it, and use it as a template like so
    [​IMG]

    Firstly you need to remove the engine cover that is held on by three 10mm nuts. These are located under the three caps that just clip in
    [​IMG]
    [​IMG]

    Once off you can clearly see the little fellow that needs to be removed going into the top of the turbo filling it with coke making those VNT nozzles nice and sticky, which in turn leads to limp mode once clogged enough, which in turn leads to a dead turbo
    [​IMG]

    Ideally you want to remove the air box lid as it will give you far more room to work, so it would be a good idea to either do this in line with a filter change to kill two birds with one stone so to speak.
    So begin by removing the cold air feed pipe. It is actually two pieces that clip together, and they come out pretty easy

    [​IMG]



    Remove the two screws that you can see above the headlight, then it simply pulls up and out as the top piece just clips into the top of the air box

    [​IMG]



    And out the way they go

    [​IMG]



    There are three little clips that hold the MAF sensor wire to the box that just pull out, two on the left, and one on the rear

    [​IMG]

    [​IMG]



    Once the wire is free unclip the MAF sensor, and unscrew the clamp that holds the TIP onto the box

    [​IMG]

    [​IMG]



    Once all these are off undo the two screws on the box itself, then the top is free to pull up and out. Got to like the fact that Audi actually bothered to put a heat shield on there too

    Once all this is out of the way the only thing holding the pipe on are two 12mm nuts on the turbo end, and two 6mm allen head bolts on the EGR end.
    If you don’t have the socket type allen bits don’t worry as they are of no use for this job, all you need is a 6mm allen key as there is no access to the inner bolt for the ratchet bits due to the turbo feed pipe.
    Once all these are off it’s just a case of wiggling it out of there which is a bit of an art, so take your time so as not to damage any threads on the turbo studs.
    [​IMG]

    You can now attach one to the turbo like so making sure you use the gasket so you don’t get any boost leaks
    [​IMG]

    The other one goes under the EGR, but as you can see the plate is thinner than the pipe you have removed
    [​IMG]

    This means that the bolts are too long, but don’t worry there is an easy solution in the form of two nuts. You simply put a nut onto each bolt before the plate, and gasket to take up the extra length like so
    [​IMG]

    Then it bolts on under the EGR like so
    [​IMG]

    Then you just have to fit a new filter and refit the air box etc and your all done.
