New investigation claims all German automakers may have colluded on diesel scandal

By now, everyone is already aware of the diesel scandal that rocked the entire Volkswagen Group. Executives from Volkswagen issued a defeat device to be installed on many diesel-powered cars that would turn off certain emissions controls during normal driving, to give the car better performance and fuel economy. But those same systems would kick back on during emissions testing, to trick the governing bodies monitoring emissions regulations. Since being caught, the entire Volkswagen Group, Audi and Porsche included, have had to issue thousands upon thousands of recalls and it’s hurt VW’s wallet as well. Now, though, a new investigation is being conducted by the EU, as there may be evidence suggesting more than just the Volkswagen Group colluded on this diesel emissions cheat.

According to Autocar, this new investigation is claiming that all¬†five major German car makers were¬†involved. So that means Volkswagen, Audi, BMW, Mercedes-Benz and Porsche. Apparently, former Volkswagen executives that left the company, or “retired”, following the famous diesel scandal have been snitching on the rest of zee Germans. The information coming from these executives states that there were secret meetings held by representatives of each brand to create a single cheat that all brands could use.

This cheat supposedly involved the AdBlue urea exhaust injection for diesel engines, which cleans up the exhaust emissions. These AdBlue tanks add weight and can be annoying to package for automakers, so they want them to be as small as possible. But making them smaller means they have to be refilled more often, annoying customers and requiring more maintenance. So the Germans are said to have designed the AdBlue system to shut off during certain temperature spikes or drops but to stay on during testing. It’s called “thermo-switching”.

Admittedly, there’s no actual proof of this as of yet. The Germans are under investigation but nothing has been proven yet. We’ll see how this plays out but it certainly won’t look well if it turns out to be true.

I've been in love with cars since I was a kid, specifically German cars. Now I get to drive them talk about them on the internet.
