Got an EGR (Engine Gas Recirculation) issue? Is the EGR clogged up? Want to avoid replacing the EGR valve?

Our diagnosis and 3-step engine carbon cleaning is your best option!

 

Why does it get clogged up? The EGR system recirculates expelled exhaust gases, because these gases contain oil residues, carbon from the burnt diesel and other such nasties the valve that controls the amount of gases recirculated, the related pipework, and if fitted a cooler (designed to cool the gases on recirculation) will over 1,000’s of miles become clogged.

This leads to symptoms such as poor engine performance, lowered fuel efficiency, engine management warning lights and the limp-home-mode being activated (restricted performance), lowered fuel economy, rough idling and/or a strong fuel odor.  We have a great wealth of knowledge and specialise in the diagnostics and cleaning of the EGR system. This includes live data analysis using dealer level diagnostics equipment that we include in all our EGR cleaning services. 

How do we clean the EGR? Firstly we’ll use our dealer level diagnostics equipment to assess the engine management error codes and complete live data analysis. Then assuming the vehicle is fit for cleaning we use a 3-stage carbon cleaning system that includes our world-leading Hydrogen carbon cleaning and our unique chemicals. This means in the majority of instances there is no requirement to remove the EGR for cleaning and assuming it’s just clogged up / dirty this will resolve the issue. On completion of the job, which takes approximately 45-60 minutes, we’ll reassess the engine management system and reset any fault codes.

    Had James do a 4 stage Carbon Clean on my Vw T5 Camper.
    Drove all the way to Kinlochleven in the Highlands about an hour after he finished . Noticed an increase in power straight away and an overall increase in MPG .
    Would highly recommend especially for older vehicles with higher mileage.

    Great service from James. Recently had my transit van remapped and can honestly say it is like driving a different van. There is so much more torque which means I’m not constantly having to change gears. James explained what he was doing and why at every stage. Will definitely be back in future

    Fantastic. Red is a gentleman. Fantastic service even though I messed him about with my appointment. Nothing was too much trouble for Red. Car is in amazing shape now. Engine running like a dream. Thanks so much Red, appreciate all your help. Best of luck for the future. �

    2 of my cars carbon cleaned 🙂 Ciaran came out and cleaned my Merc and Peugeot, I've had the peugeot 9 years and it has never started or run as smoothly as it does now, the Merc I've had about a year and it now starts first flick of the starter, amazing, especially considering my OCD/Servicing /Tinkering that I subject all my vehicles to! 🙂 Ciaran was helpful, knowledgable and professional. He also cleaned my friends VW Caddy van, which also now runs better than at any time in his 3 year ownership. I'd recommend this service to anyone.

    Had my Sprinter van remaped today, great service very friendly and explained everything he was doing in a fairly simple way that even I could understand. Van is now going great, it's 11years old, and pulling like a cheap hooker. Came home and pulled a mini digger and trailer up a very big hill no worries.

    Had my Jaguar XK8 carbon cleaned today, it's made a noticeable difference in the way the car runs, whether it will improve the mpg time will tell.
    All in all well worth doing.
    Thanks Redha!

    James did a re-map on my transit 2.2 140ps and even though the van wasn’t exactly gutless before, it definitely has more torque & power after the map.
    James was spot-on and he offers a service that I’d highly recommend. �

Citroen C3 EGR carbon cleaning with client review

UNDERSTANDING THE EGR VALVE SYSTEM

The purpose of the EGR (Engine Gas Recirculation) system is to reduce nitrogen oxide (NOx) emissions that primarily forms when nitrogen and oxygen is subject to high heat and pressure. Nearly all modern diesel and some petrol engines require an EGR system to meet emissions regulations. The system is designed to recirculate exhaust gases back into the intake system which reduces either O2 in diesel engines intake stream or combustible matter in a petrol engines intake stream. These gases have little or no ability to react to the second combustion cycle they are subjected too thus helping to reduce combustion heat and in-cylinder temperatures.

Unfortunately, these recirculated exhaust gases carry a lot of carbon, unspent fuel (including varnishes) and oil vapour which gradually accumulates and bonds as carbon particles inside the inlet and re-circulatory system and especially on and around the valve itself. This leads to numerous engine problems and worst case even engine failure.

The specific purpose of the EGR valve determines if, when, and how much exhaust gases are recirculated. As carbon deposits build up in and around the valve it prevents the opening and closing of the valve operation, and worst case the valve can become stuck losing all functionality.

Usually, the initial driver symptoms of the clogging of an EGR valve is loss of power, excessive black smoke under load, engine management lights, limp mode, and engine stalling, especially when coming offload. Eventually, the valve will stick in either the open or shut position. If stuck open the carbon build up saturation will be accelerated whilst if stuck shut it will cause excessively high emissions and ultimately MOT and/or roadside emission test failures.

How to clean the EGR Valve

There are numerous ways to clean or replace the EGR valve with varying prices.

The costliest option is a complete replacement part and a clean. Most mechanics will recommend this – Why? Because they’ll earn a profit from the part and it’s a quicker job for them. The price of a EGR valve varies on average between £300 and £1,500 plus labour for fitting. At the time of replacement, or just before, it’s important that the rest of the EGR system is also cleaned otherwise carbon deposits within the rest of the system will likely clog the new component. 

The moderately expensive alternative is to remove the valve and manually clean it which requires mechanical skill and time. The problem is not all valves are so easy to remove and refit and the outcome may not always be successful. Of course, it’s not just the valve though, there are all the associated pipes and if fitted the cooler that must also be cleaned. Expect prices to be anywhere from £200 – £500 for such a job if done correctly rather than just the valve.

Then there’s our service, the most cost-efficient option. Even if the valve has failed and therefore the clean doesn’t resolve a valve issue completely at least the rest of the EGR system will be cleaned ready for a new component which on its own will save you money!

Preventative cleaning starts from as little as £89.99 (for a car)
