[QUOTE="leforte, post: 293114, member: 1943"] sorry my bad. bmw engine dont use any EGR at all. what i meant to convey above is the secondary injection that is used by bmw engines to meet the emission regulation for LEV and ULEV for the m54b30 engine. there is valve that is part of the air injection system but it does not recirculate like the EGR into the intake manifold. the secondary air injection system is only found on US spec cars. all other euro spec cars including the jap spec models may not have it. to be sure if your car has one, just look for a black colour looking pump next to the radiator expansion tank. attached is the image of the system. item number 1 is the secondary air pump and item number 7 is the control valve.
