The primary of the ​​​EGR (Exhaust Gas Recirculation) is to help with emissions. It achieves this by recirculating a controlled amount of air from the exhaust, back into the engine, through the air intake, thus reducing the level of carbon toxics being passed out.

It is the job of the EGR to regulate the time/amount of gas being passed through and cooled.  

With these deposits of gas, carbon can often build up and contribute to the EGR system failing, and even lead to engine failure.

Removing the EGR system, by closing the values and reprogramming the ECU, helps improve throttle response, economy, engine life and carbon deposits.


Dragon Tuning can provide this solution for as little as £250. Please contact us if you require more details.



Since 2004, as part of the exhaust emissions standards, new cars have had the need for a DPF as part of the exhaust system. The majority of the cars manufactured after 2005 will have a DPF fitted. If you are unsure if your vehicle is fitted with one, you can contact us or you can be sure to find the answer online.


Diesel Particulate Filter problems are becoming quite common. In most instances, the DPF fails to clear itself; this is known as ‘automatic DPF regeneration’ whereby fuel is injected into the system when at high temperature, resulting in the burning off of soot in the filter. This failure can lead to blockage of the filter, leading onto failed filter and the car engaging limp mode. The build up soot and failure of the DPF will result in lights becoming illuminated on your dash board; this could cost you up to £2500 to get fixed.


​If you are experiencing any problems with your DPF, speak to us to see if we can help.


​Our prices start from £200! The process shouldn't take longer than a few hours.



​For more information on soot build up and on DPF failure, there are many articles available on the web, or feel free to get in touch with us.
