EGR removal, frequently asked questions

Is EGR Removal cheaper than EGR replacement?
In almost every case, absolutely yes. Replacing a faulty EGR unit usually involves having to fit not just a new valve, but also connecting pipes, replacement sensors and other items. Even when replacing an EGR unit, it is usually necessary to reprogrammed] the vehicle's engine management computer. Both parts and labour costs are inevitably substantially higher for replacement than for removal.

Are the vehicle's performance and economy affected?
Yes, but usually for the better! In the vast majority of cases, both performance and economy are improved by the removal of EGR systems. This is the case even if the vehicle was performing 'correctly' prior to the work being carried out. In the case of a faulty system, performance and economy are likely to be significantly enhanced.

Can you carry out EGR removal on any vehicle it is fitted to?
Virtually always. The correct procedure involves reprogramming the engine management computer. In fact, this is essential and if it cannot be done, we would not contemplate carrying out the work. There are a very few unusual or highly specialised vehicles for which engine management 'maps' and prgramming details are not available. In these circumstances, replacement may be the only option.

Should I inform my insurers if I have EGR removal carried out?
Yes, you should do so. It is a modification to the vehicle's exhaust system that differs from standard specification. However, there are no commonly available figures for power increases and this work is normally carried out for reasons of economic maintenance. It is unlikely that your insurance premiums will be affected. Nevertheless, all insurance policies contain a clause stating that the insurer should be informed of any modifications to a vehicle.

How quickly can the work be carried out?
Complete EGR removal, together with engine management reprogramming can normally be done within a day and frequently in just a few hours. Only if any serious problems are encountered will there be any delay.

Is EGR removal legal?
Yes, completely. Manufacturers of new vehicles are obliged to meet exhaust gas emissions standards in various countries, and the fitment of an EGR system is a simple way to accomplish this. The fitment of an EGR system in itself is not a legal requirement, nor is it an MOT requirement. Provided the engine management system is correctly setup and programmed after removal, emissions are likely to be close to, or match, new vehicle figures and will easily pass any MOT requirements for used vehicles.

Is the work guaranteed?
Yes. We offer a limited warranty on all such work and an extended warranty on the engine management programming.
