BMW of North America is recalling 44,368 model year 2013-2018 BMW 328ds and 328d xDrives, model year 2014-2018 328d Sports Wagons and 328d xDrive Sports Wagons, model year 2014-2016 535ds and 535d xDrives, model year 2015 740Ld xDrives, model year 2015-2017 X3 xDrive28d SAVs and model year 2014-2017 X5 xDrive35d SAVs 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. The high EGR temperatures may result in these particles possibly smoldering and melting the intake manifold, increasing the risk of a fire.
What to do
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.
Owners may contact BMW customer service at 1-800-525-7417.
