In a scene reminiscent of the Volkswagen dieselgate saga of 2015, BMW Group has denied recent allegations that their Euro 6 diesel vehicles do not provide adequate exhaust gas treatment.
The premium German brand has tried to distance itself from claims that the AdBlue exhaust gas treatment tanks are too small and are not meeting real-world emissions claims.
BMW has claimed that their technology is different from other systems on the market and employs various components to treat exhaust fumes. In an explanation, it was suggested that the combination of a NOx-storage catalytic converter, urea injection with AdBlue and exhaust-gas recirculation leads to a lower consumption of AdBlue when compared to the systems used by other makers. It was also suggested that the refilling of AdBlue was simply done via the tank lid or engine hood (depending on the model) and would, therefore, be easy to maintain the legally required emission figures.
Due to this system, BMW sees no need to recall or upgrade the software of the BMW Group Euro 6 diesel passenger cars. They do remain committed to voluntary software upgrades for suitable Euro 5 diesel passenger cars at no cost to customers.
Whilst none of this will affect Australian BMW owners, given the ramifications of the Volkswagen diesel scandal, it will be interesting to see if there is any backlash from these allegations.
Let’s start a Car Conversation, with all the recent drama surrounding diesel emissions and the difficulty to continually improve engine efficiency, how long until the diesel engine is retired from passenger cars?
