Reconfigure and eliminate the Exhaust Gas Recirculation (EGR) system


Recommended Posts

Apologies if my question has been previously addressed, but despite my efforts to search, I have been unable to locate the solution.

I have scheduled an appointment on Thursday to have my 2011 C250 CDI undergo a remap, during which I have chosen to have the EGR function deactivated in the vehicle's software.

I would want to know whether this modification alone would sufficiently disable the EGR system, or if, similar to my past non-Mercedes vehicles, I will also need to install a blanking plate or totally disconnect the valve.

The engine of my vehicle is the OM651.

Thank you in advance

That would render it unlawful for road usage and it is also necessary for the regeneration of the diesel particulate filter (DPF). To ensure certainty, you would need to block it off.

I had the exhaust gas recirculation (EGR) system 'delete' performed on my 2007 OM642 engine. The business that conducted my mining operation said that the use of a plate was unnecessary (I suggest consulting your own company on its need). Additionally, they clarified that they do not entirely eliminate the plate, but rather adjust the valve opening to a minuscule percentage. I hypothesised that by doing so, the automobile maintains the belief that it still has the valve, yet the quantity of gases being recirculated is negligible.

The majority of exhaust gas recirculation (EGR), diesel particulate filter (DPF) and decat police officers may be found in vehicle forums rather than engaging with real-life situations.

I first believed that the exhaust gas recirculation (EGR) system was necessary for the proper regeneration of the diesel particulate filter (DPF), but I was promptly corrected by the firsthand experiences of a highly skilled tuner.

A blank is only necessary for a defective partly open EGR valve.

I deactivated it in the Engine Control Unit (ECU), but he informed me that a little quantity of petrol may still get through. Therefore, I installed a blanking plate.

I strongly discourage anybody from tampering with the vehicle's emissions control systems, since it is a self-centered and thoughtless act towards others.

However, based on my understanding, the act of removing the EGR (Exhaust Gas Recirculation) system is not explicitly prohibited by law. Refer to the information provided below:

What are the reasons for people's desire to eliminate it? If the automobile becomes too unclean, it should be cleaned. Alternatively, if you drive a little distance, consider purchasing a gasoline-powered vehicle.
Merely to exacerbate the level of pollution.... For clarification, I am not Greta.

I get why individuals are dissatisfied with the prospect of black, sooty emissions being reintroduced into the intake manifold and consumed by the injectors.

However, I strongly advise against tampering with the EGR system since it plays a crucial role in reducing NOx emissions. Which are detrimental.

Many individuals choose to remove or erase it due to the many problems it causes. (Whether justified or not) I somewhat see why individuals would feel that way, but I myself have not and will not.
The emissions would not be significantly altered, and the removal of the EGR system would not result in any fatalities.

The reason for my action was just that. As someone employed in the automotive industry, I have seen several instances of contaminated intake manifolds and swirl valves due to the combination of the exhaust gas recirculation (EGR) system and the presence of oily vapours from the positive crankcase ventilation (PCV) system.

I removed the exhaust gas recirculation (EGR) system from my previous Audi 1.9tdi only for the purpose of assessing its condition. I was astounded by the complete obstruction, a single massive formation of carbon that was completely immobilised. It may have been completely blocked off.
The car performed really well and consistently passed the emissions test with flying colours. The tester even acknowledged the impressively low results. Therefore, I doubt the extent to which they really have an impact. Although I thoroughly cleaned it, I did not see any noticeable change afterwards.

I am certain that Volkswagen has compensated for any harmful emissions resulting from individual blocked EGR valves via their extensive scandal involving diesel emissions from their cheating device. I would engage in any activity that brings you a sense of joy and satisfaction.

There is nothing that can be done to improve a design that is both hopeless and outdated.

It decreases the amount of NOx, but does not completely eradicate it, while also causing various harmful effects.

The combustion cycle of diesel fuel results in the production of incomplete combustion byproducts, such as soot, which consists of partially burned fuel molecules.

The soot and recirculating crankcase oil vapour mix to form a very viscous substance known as super gunk.

Additionally, there are these remarkable electronic control unit (ECU) emissions upgrades that will result in a greater opening of the exhaust gas recirculation (EGR) valve, leading to an increased accumulation of pollutants.

Automobiles that often travel on the motorway have a reduced likelihood of experiencing carbon buildup in their intakes. Those who drive to get a little quantity of milk are the ones who express dissatisfaction about the impact of diesel pollution devices on their vehicles.

If your excursions are brief, it is advisable to go for a gasoline-powered automobile.
