    If you try to make a search, you'll find that with EGR disconnected, the engine is warming up slower, especially not very ok in the cold season. In some cases, EGR helps to avoid backpressure. Turbo is spinned by exaust gases, and without EGR, there could exist a pressure and cause shocks to turbo, but if you drive normally, i think this thing will be rare.
    On the other side, you'll have a clean engine, because exhaust gases doesnt go again into intake manifold. Personally i didnt feel any difference between EGR and non-EGR..i feel just a bigger fuel consumption and a slower warmingup of the engine.

    The only fact that most people really care about regarding running with no EGR is that:

    The turbo will spool quicker as more exhaust gases will exit through the turbo instead of recirculating.

    That's all that matters

    When I had my car remapped, I asked them to also delete the EGR function. However, he couldn't be sure he'd been able to stop it working so to test it I took the vac pipe off the EGR valve. Can't say I noticed any difference at all in the running of the engine with the valve disabled but the emissions light eventually came on about 100 miles later indicating that it was still in the ECU software so I reconnected the pipe and the light went off again.

    There is no debate about the turbo spooling faster, it is an engineering fact. Whether you feel it or not is subjective though
