EEC Managing Director comments on DPF removal
Published on: 19/04/2016

EEC is committed to educating the aftermarket with industry best practice, and is a passionate advocate for the correct treatment of DPF’s and their associated technologies. Paul Clark, Managing Director, offers this timely advice.

DPF removal is a risky business. Not only will it invalidate your car insurance and potentially fall under the veil of tax evasion, due to low emissions based road fund licensing, but it can damage the performance of your vehicle as well.  Removing the DPF will mean the ECU will need re-mapping and where in the short term people may feel they have ‘solved a problem’ they will eventually find mores issues arising with the vehicle as a result.

At EEC we have heard many horror stories about vehicles in limp mode, engine management lights on and poor running performance and actively warn people of these dangers through our technical seminars. With EEC’s sister company Revcoat Technologies, we have the capability to provide a cost-effective  aftermarket alternative to the high costs of DPFs expected by the VMs, without compromising performance or functionality. We also offer the industry unique DPF diagnostic tool which can allow you to perform all the service and maintenance functions required for a DPF equipped vehicle, potentially solving the problem before removal is even thought about.

Many things can negatively impact the operation of the catalyst and DPF; Problems with injectors, throttle bodies, EGR valves, MAP sensors, MAF sensor and IAT sensors. Additionally, incorrect oil grades, poor servicing, dirty air filters and inappropriate drive cycles can all create problems. Look at all the options available to you in the aftermarket before considering a removal, as just removing the DPF will not necessarily be the answer.
