All you need to know about EGR valves

 

EGR Removal / Delete

At some point during your time of owning a modern vehicle, you will most likely experience EGR problems. In this article, we’ll explain everything you need to know.

So, what is an EGR valve?

Firstly, EGR stands for Exhaust Gas recirculation. A valve situated between the exhaust and intake manifold. Its job is to recirculate some of the exhaust gasses back into the engine via the intake system which reduces the amount of toxic gas (NOx) released into the atmosphere.

 

 

Common Problems with EGR valves

Engines create hydrocarbons in the form of soot. Over time soot builds up in the intake system and the EGR valve which often causes them to fail. There are two types of commonly used EGR valves, old-style vacuum operated and the new style electronic. Both are susceptible to carbon build-up which results in a repair bill up to £500.

 

 

When the valve fails you will experience one of the following symptoms, increased fuel consumption, loss of power, rough running and limp mode. Often the engine management light will illuminate and on some vehicles, the glow plug light will flash.

 

EGR Removal / Delete

Luckily for our customers, we can provide a solution for this problem. In some cases, we can remove the EGR valve completely but these removal kits can be costly and poorly made. We prefer to use a blanking plate which is more time-efficient and cost-effective for our customers. The vehicle will then need the EGR software reprogramming to stop any warning light from returning.

By blanking the EGR valve you can expect an increase of 10-15% in fuel economy, improved throttle response, increased power and reduced carbon deposits in the engine.
