In a series of investigations that takes us back to the infamous Dieselgate scandal, BMW finds itself under scrutiny by German regulators over allegations of using illegal defeat devices in its diesel vehicles. The German Federal Motor Transport Authority (KBA) has identified unauthorized defeat devices in certain BMW Sports Utility Vehicles (SUVs), specifically in some diesel models, including the X3 2.0d.
These devices are alleged to manipulate exhaust emissions to meet regulatory standards under test conditions, a practice that contravenes European Union emissions laws.
The KBA’s findings suggest that these defeat devices were employed in vehicles produced before 2014, affecting an estimated 33,000 X3 SUV models in Germany and potentially 100,000 to 150,000 vehicles across Europe. BMW, while cooperating with the authorities, has proposed a set of measures for hardware and software updates to address the issue.
The manipulation involves reducing the exhaust gas recirculation when the air conditioning is switched on and under normal operating temperatures, which is deemed inadmissible according to the European Court of Justice rulings.
This investigation was sparked by research from the German environmental watchdog Deutsche Umwelt Hilfe (DUH), which accused BMW of significantly lowering nitrogen oxide emissions during test conditions by deactivating or reducing the effectiveness of exhaust gas filtering.
This manipulation was notably observed when the air conditioning was turned off, a condition not present in official testing environments. The DUH’s findings have led to a broader investigation by the KBA, focusing on the software program within the BMW X3 2.0d’s engine management system.
The allegations against BMW are part of a larger pattern of emissions cheating that has implicated several automakers since the Dieselgate scandal first broke. The scandal, which began with Volkswagen, revealed a widespread practice among car manufacturers of using defeat devices to circumvent emissions regulations, leading to significant financial penalties and a substantial decline in the market share of diesel vehicles in Europe.
BMW’s response to the allegations has been cautious, with the company denying the use of defeat devices but expressing its commitment to cooperating with the KBA to resolve the issue. The company has refrained from commenting further while the investigation is ongoing, although internal documents suggest BMW is attempting to frame the issue as a “production defect,” which could potentially limit the repercussions to a recall of the affected vehicles.
However, if the KBA finds evidence of intentional fraud, BMW could face civil and criminal penalties, further damaging the automaker’s reputation and potentially leading to a broader examination of its diesel vehicles. This situation underscores the ongoing challenges facing the automotive industry as it navigates the transition to cleaner technologies and the scrutiny of regulatory compliance practices.
The investigations into BMW’s alleged emissions tampering highlight the lingering shadows of the Dieselgate scandal and the automotive industry’s complex relationship with environmental regulations.
As regulators tighten emissions standards and the industry moves toward electrification, the legacy of defeat devices and emissions cheating continues to influence public perception and policy discussions around diesel technology and automotive environmental practices. As of 2022, the share of electric cars in total car sales already reached 14%, more than tripling compared to 2020 (4%).
