After Dieselgate, numerous 1.6 TDI and 2.0 TDI engines are struggling with persistent EGR problems. But why? And how does Auto Elect offer a lasting solution thanks to reverse engineering?<\/b><\/p>\n

Since the Dieselgate scandal, the EGR valve<\/a> - the part that directs exhaust gases back into the engine to reduce NOx emissions - a source of frustration for many car owners and workshops. What was once intended to make engines cleaner has, in practice, turned out to primarily result in expensive repairs, downtime and dissatisfied customers. At Auto Elect, therefore, we have taken a structural approach: reverse engineering<\/a>. Thus, we do not just supply a replacement part, but a technically improved solution.<\/span><\/p>\n

What went wrong after Dieselgate?<\/b><\/h2>\n

To understand why so many EGR systems fail, we need to go back to Dieselgate for a moment. VAG group engines, such as the EA189, were equipped with software that recognized when the car was on the test bench. During such a test, the EGR system worked at its maximum to reduce NOx emissions. But during normal driving, the system was largely turned off. This resulted in smoother performance and less pollution in the EGR system itself.<\/span><\/p>\n

Upon discovery of this practice, governments required the manufacturer to perform a software update. As a result, the EGR valve now had to remain active at all times. Good for emissions figures according to the standard, but the original system was not designed for this. The result: excessive pollution, stuck valves, faulty engines and frequently recurring malfunctions.<\/span><\/p>\n

The problem with the original design<\/b><\/h2>\n

The original EGR system was already prone to fouling, especially in combination with aging particulate filter. The software update required the system to run permanently, increasing the load tremendously. As a result, EGR valves clogged or failed more quickly. And because the exact same original parts were often fitted, the problem kept recurring.<\/span><\/p>\n

Workshops and customers were powerless: replacements sometimes helped briefly, but did not provide a structural solution. To everyone's frustration.<\/span><\/p>\n

What does Auto Elect do differently? Reverse engineering.<\/b><\/h2>\n

At Auto Elect<\/a> we analyze not only what breaks down, but more importantly <\/span>why<\/span><\/i>. Based on reverse engineering, we identified and addressed the weaknesses of the original design of the VAG EA189 engines. This resulted in a modified EGR module within our Gaured program, specifically suited for the higher load after the software update.<\/span><\/p>\n
