Coolant Leak Within EGR May Cause Fire in Nearly 45,000 BMW Vehicles
dealers will Replace the EGR and the intake manifold, if damaged
BMW is recalling certain 2013-2018 BMW 328d and 328d xDrive, 2014-2018 328d Sports Wagon and 328d xDrive Sports Wagon, 2014-2016 535d and 535d xDrive, 2015 740Ld xDrive, 2015-2017 X3 xDrive28d SAV and 2014-2017 X5 xDrive35d SAV vehicles equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler. If the EGR cooler leaks internally, the coolant can mix with diesel engine soot, possibly causing a fire.
What's the problem?
This safety recall involves the Exhaust Gas Recirculation (EGR) module with an integrated cooling component ("cooler"). Over time, it is possible for an internal leak to start within the EGR cooler. About 44,368 vehicles are affected.
During vehicle operation, if an internal coolant leak were to start within the EGR cooler, the fluid could mix with normal diesel engine soot/sediment. In combination with high temperatures normally present in the EGR module, this might result in smoldering particles. In very rare cases, this could lead to the melting of the intake manifold, and in extremely rare cases result in a possible fire.
During vehicle operation, the driver may be alerted to this condition by one or more of the following: A warning symbol in the instrument cluster displaying a loss of engine coolant, a reduction in engine power, an unpleasant odor (exhaust gas), an unusual noise from the engine compartment, and/or smoke from the engine compartment.
What happens next?
BMW will notify owners, and dealers will inspect and replace the EGR cooler as necessary. If a leak has already occurred, the engine intake manifold will also be replaced. These repairs will be made free of charge. The recall is expected to begin December 17, 2018.
