Hello to all! I have a seat leon 2.0 tdi bkd 140 hp 2006. A year ago you broke off the egr, and I replaced it. On the net I read that has more? a function. In addition to the reasons ecologists, to recirculate the exhaust gas, is also serving in the phase of the shutdown of the engine, for "smother" with air rich in CO2, avoiding in this way that the machine turns off "knee-jerk" (which happened to me when the same valve is cracked), going to damage the flywheel (in the long term).
That said, my question ?: going to delete the egr via the ecu, this functionality? is preserved? Why? this ? there? that inhibits me from closing it.
Sorry if my ? a trivial question... Maybe someone else has the same doubt.
