Hot Intake

This bulletin applies to 2014-2018 BMW models built from September 2012 to June 2017. BMW issued a recall for certain 328D, 328 xDrive, 535D, 740LD xDrive, X3 xDrive vehicles equipped with an 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.
