    EGR stands for 'Exhaust Gases Recirculation', or at least I think it does.

    And what the EGR system does is (again by my limited understanding), is whereas a car normally emits all the unburnt fuel etc., straight out of the engine and down the exhaust pipe out into the atmosphere, if an EGR system is in place, the exhaust gases are rediverted back into the inlet system of a vehicle by a valve system that links the exhaust side to the inlet side so the engine then burns them again, leading to less unburnt fuel etc. in the final exhaust gases emitted by the vehicle.

    Obviously it's not diverting all the emissions all of the time, else the gases would end up going round and round and round in circles, with more and more being added all the time by the inlet side until the engine blew itself to bits under all the pressure.

    Don't quote me on the above as as I've already said, my understanding is a bit basic on this one, but I think the above covers the basic concept of the EGR process.

    Steve has just about nailed it there.
    Obviouslyas unburnt and very hot gasses are being fed into the inlet side of the engine the engine management system has to very carefully monitor the input and accurately inject the correct amount of fuel and 'cold air'.
    If the EGR valve goes u/s this obviously fails to work correctly and leads to poor running
