DPF & EGR Delete

If your DPF warning light or Anti-Pollution warning is on, please do not ignore it. Get professional advice, consider your options carefully and attend to the problem. Leaving it will ultimately cost you much more in additional repair bills and it can be dangerous.

DPF Recalibration – If you have had your DPF core removed, we are able to recalibrate your vehicle's ECU to stop your engine going into limp-home mode and clear the DPF warning light. You must be aware of the legal implications (as below) of this being carried out and act responsibly. 


The EGR valves can become clogged with carbon deposits, causing them to fail or stick. The result of this causes error codes and the vehicle not to run correctly. Our software solution to disable the EGR valve is a simple and effective method of improving the efficiency of your engine.

Removal of the EGR system by Blanking off the exhaust input and reprogramming of the engine management ECU results in lowered engine temperatures, improved throttle response, economy and also can lengthen engine life by reducing oil contamination and carbon deposits.


In February 2014 the UK government brought out a visual inspection as part of the annual test for road vehicles. The tester must now look for the presence of a DPF filter section in the exhaust. 

A missing DPF, where one was fitted when the vehicle was built, will result in an MoT failure. A vehicle might still pass the MoT visible smoke emissions test, which is primarily intended to identify vehicles that are in a very poor state of repair, whilst emitting illegal and harmful levels of fine exhaust particulate. It is an offence under the Road Vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.


Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use. The potential penalties for failing to comply are fines of up to £1,000 for a car or £2,500 for a light goods vehicle.
