    Hi all,
    EGR in my 2010 Linea MJD seems damaged. Abnormal sound from the engine bay is the symptom.
    EGR is blocked temporarily.

    1. Is EGR a must for the engine's normal function, except it reduces pollution ?
    2. Will blocking crate any long term problems?

    Pls elaborate.

    Thanks for the time...

    If yours is a bs4 mdoel, you cannot physically blank it because it will throw an error but if your car is a bs3 model, you can do it. In a bs4, youll have to remap the ecu to disable the egr. It will improve performance a bit and increase nox emissions. But personally i believe, letting the engine run on cleaner air without egr will have lesser particulate matter emission. Clogged/faulty EGR does more harm than good. It just ruins the intake and I really hate the black cloud from exhausts.

    And was your egr leaking?

    Like gkrish said, if the engine is bs3, there should not be any issues. After intake cleaning I have been running for around 3k Kms with an unplugged egr and had no issues. There is difference in low end torque to the positive side. Even I said the fas that I have been running with unplugged egr and they seemed to have no issues. So I have decided to keep it unplugged for the time being.
