Volkswagen has released a new video on YouTube today. They claim the video shows the proposed fix for their small diesel engines. 1.6L and 2L TDI engines currently break emissions limits in both the EU and North America by a substantial number. VW claims the hardware, a plastic mesh device, works in tandem with a software fix applied to the car’s computer system. Their fix is designed to change the way the air flows over the mass flow sensor. Using this new data, the mass flow sensor will control the volume of fuel required in the mix, causing a cleaner burn and less noxious exhaust. It should be noted that because North American and European emissions standards differ widely, this fix won’t be for anybody on this side of the pond. There is still no indication from VW when a fix can be expected in North America.
In the meantime, all Audi, Porsche and Volkswagen cars with diesel engines, all sizes, have been pulled from the market. VW has been battling legal and public relations issues since it was revealed in early October that their cars violate international pollution laws, despite testing showing they did. VW employs a software fix to fool testing into passing, but real driving tests show VW engines produce as much as 40 times the limit of nitrogen oxide. There is already a proposed fix for the larger 3.0L diesel engines, again only for European versions. Some questions remain on the validity of the fixes, considering the larger engines were only fixed with a software patch, but smaller engines have required this hardware and software combination. Volkswagen says the fix is permanent, and should only take about 20 minutes.
Take a look at the official video demonstrating the fix and let me know your thoughts in the comments below.
