BMW 540D Recalls

The BMW 540D has 2 recalls, both affecting 2018 540d xDrive models, where the exhaust gas recirculation cooler can leak internally, mixing coolant with diesel soot to produce smoldering particles that melt the intake manifold and can start an engine fire. These two recalls describe the same underlying defect. The second recall covers 2018 540d xDrive vehicles where the prior repair performed under the first recall did not fully resolve the issue, meaning some vehicles may have had the EGR cooler replaced and still remain at risk. The failure mechanism is the same in both cases: internal leakage inside the EGR cooler allows coolant and soot to combine, generating heat buildup that degrades the intake manifold and creates fire conditions in the engine bay.
