Courtesy of BMW OF NORTH AMERICA, INC. INDEX EXPLANATION CHART AIR INTAKE SYSTEMS The intake air ductwork differs between the E70 and E90. Both vehicles will draw air from behind the kidney grill. On the E70, the air filter housing and silencer is located on top of the engine. On the other hand, the E90 has a filter housing on the passenger side inner fender.

INDEX EXPLANATION CHART Swirl Flaps The US version of the M57 engine utilizes the previously known swirl flaps which are located in the intake manifold. The primary difference is that the swirl flaps are now controlled electrically, rather than with vacuum. This method of actuation also provides a means of position feedback with the DDE system to comply with OBD requirements. An additional benefit of this method of control is a more precise positioning of the swirl flaps as needed. The flaps are map controlled using engine speed, engine load and coolant temperature.

There are special provisions for the SCR system as well as for the US specific OBD monitoring of the DOC. Each system is unique to the vehicle with different muffler and tailpipe features.
