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 heard a lot of good things about this young mans work. Seemed too good to be true but decided to give it a try I am so glad I did. James arrived right on time he said. Explained everything he was going to do to car and told me he expected I would get at least 46 mpg .At the time my Ford galaxy was getting 43.5mpg. Also car would have more power to it. Well when he had finished I took car out for a run .It seemed as though I was driving a new car. Very smooth and lots more power as I realised when I overtook traffic. His next promise was mpg .He came up trumps on that too. From 43.5mpg.I am now getting 47.3 mpg. I would highly recommend this young man and his services. Great job and reasonably priced. Thank you JamesPrince Robinson

Sent them a request late on Saturday evening, didn't think they would get back to me until the following Monday... but Paul replied really quick, booked it in for this morning! That's what you call efficiency! Had a stage 3 clean today and the car feels much smoother.
Jay who came to sort the job was polite professional and friendly.
Top marks all round, great service!Darren 'del' Knaepel
Professional friendly and reliable service! I would highly recommend Sean to anybody!
i had my civic type r done sean turned up on time talked me through the whole process and answered any questions i had, carried out the clean and was very professional, after the clean was done he waited while i took it for a spin and i was very happy with the results, it now idles better and flat spot has gone with the engine running alot smoother! definitely recommend a clean by sean at UKCC Auto Techs - Cambridgeshire

Hi guys got Red to carbon clean my vauxhall insignia last week ( stage 3) what a big difference it has made definitely more responsive on the pedal and no smoke talked me through everything he was doing well happy cheers Red next year pal and please let me know on that stage 2 remap when ur up and running / definitely recommend it guysKenny Ross
Just had a stage 3 clean done by James on my 407 coupe 2.7 L hdi , I thought it was running fine before the clean and any minor things were just age related, how wrong was I !!! It’s not running like it’s came out the showroom floor yesterday
Notice difference in how smooth it running
How quiet it’s running idling and at speed
Can’t recommend UKCC Auto Techs enough
And James who does south Scotland and Newcastle and Carlisle areas TOP BLOKE

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.
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)
