BMW is issuing a recall for a limited number of 2018 BMW 540d xDrive Sedans due to a defective exhaust gas recirculation (EGR) module. This component plays a crucial role in reducing emissions by recirculating a portion of the exhaust gases back into the engine.
However, in certain cases, the EGR module can develop a leak and allow coolant to enter the system. When coolant mixes with the soot and high temperatures present in the diesel engine, it can create a hazardous situation.
The resulting smoldering particles can melt the intake manifold, potentially leading to an underhood fire. This poses a significant safety risk to both the driver and passengers.
BMW has identified that some vehicles may have received an incorrect EGR module during a previous recall intended to address this issue. To rectify the situation, the automaker is now inspecting affected vehicles and replacing both the EGR module and intake manifold as necessary. This process will be carried out at no cost to the owner.
Owners of 2018 BMW 540d xDrive Sedans can determine if their vehicle is included in the recall by entering their 17-character VIN on BMW’s recall portal. If their vehicle is affected, they will be notified by mail and can schedule an appointment with a BMW dealership to have the necessary repairs performed.
BMW emphasizes the importance of addressing this issue promptly to mitigate the risk of an underhood fire. By replacing the faulty EGR module and intake manifold, the automaker aims to ensure the safety and reliability of its vehicles. BMW’s B57 diesel engine, once a cornerstone of their North American lineup, has been discontinued in favor of gasoline-powered hybrids.
Despite its impressive power output and fuel efficiency, the diesel engine couldn’t withstand the changing market dynamics. The B57, with its twin-turbo setup and advanced technology, was a standout in its class. However, the shift towards electric vehicles and stricter emissions regulations made it difficult to justify the continued production of diesel-powered models.
The B57’s discontinuation marks the end of an era for BMW. The diesel engine offered a unique driving experience, combining power and efficiency in a way that was unmatched by gasoline-powered engines.
The B57’s twin-turbo setup allowed it to deliver a surge of torque at low speeds, making it ideal for highway cruising and towing. Additionally, the engine’s fuel efficiency helped to reduce operating costs.
However, the B57’s future was always uncertain. The increasing popularity of electric vehicles, coupled with stricter emissions regulations, made it increasingly difficult to justify the continued production of diesel-powered models. In the end, the B57’s discontinuation was a logical decision, but it still represents a loss for those who appreciated the unique qualities of this engine.
