Want to avoid or reduce excessive exhaust smoke? Failed your MOT emissions test? Embarrassed by the smoke trail you leave behind you?
Our diagnosis and engine carbon cleaning is your best option!
Why does it smoke? There are many reasons why a vehicle will smoke excessively. The main ones are inefficient combustion, leaking injectors, clogged EGR valve, failing turbo, blocked DPF or catalytic converter.
We have a great wealth of knowledge and specialise in the diagnostics of excessive smoking issues or resolving MOT emissions failures. This includes live data analysis using dealer level diagnostics equipment that we include in all our carbon cleaning services.
How do we resolve excessive exhaust smoke or high emissions causing MOT failures? 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 2-stage (for petrol naturally aspirated engines) or 3/4-stage carbon cleaning (for petrol turbo or diesel engines) that includes our world-leading Hydrogen carbon cleaning and our unique chemicals. On completion of the job, which takes approximately 45-60 minutes, we’ll reassess the engine management system and reset any fault codes.

Just had James out to do two of my work vehicles - Mercedes sprinter & Toyota hilux.
Can see a massive difference already. James was kind enough to explain the whole process and answer any question. Turned up on time, polite and great communication leading up to our meet. Top class, will definitely use again. �

Highly recommend, I’ve got a 07 plate transit that has been decreasing in power and more and more smoke coming from it the past few weeks. So decided to give these guys a call he came out Friday evening, took about 45mins the difference in my van now is night and day the power it now has and the smoke from the exhaust is gone thanks a lot GPaul Scicluna
Had Ciaran carbon clean my Vauxhall vivaro this evening.
Very nice guy to chat to. Didn’t mind me watching and asking questions. Very knowledgeable due to his background.
I’ve taken my van out for a little test run to see what difference the job has made and I am totally surprised at how well the van drives now.
It’s a lot quieter, drives with a little more gusto than before and even the exhaust smells cleaner.
I highly recommend Ciarans service. I’ll be telling a lot of people about how great it is.

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 James

I've done the 3 stage cleaning on my Ford Galaxy tdci. The result was great, as promised. The car is now smoother, quieter, has more power throughout the rev range and my average fuel consumption dropped from 38-39mpg to 40-42mpg. I'd strongly recommend it to everyone, even for low mileage cars.Di Riddell
Very speedy service, phoned on Saturday, arrived Monday morning and car back up and running Monday lunchtime! James is a lovely guy, very easy to chat to and happily explained the process and readings. Car was in limp mode before the process and now working again so very pleased. Wouldn't hesitate to recommend this professional & friendly company.
Exhaust Emissions and MOT testing
In an effort to reduce pollution and Greenhouse gases most UK road going vehicles must meet set emissions standards. You can read more about these standards and MOT emissions testing here.
Exhaust smoke colour relates to different engine issues
Too much white exhaust smoke?
White smoke is condensation caused by hot liquid vapors coming into contact with cold air as it exits the exhaust.
It’s perfectly normal for a vehicle to exhale some white smoke from a cold start, especially in cooler weather. The longer the vehicle has sat unused the more chance there is that some water vapor has accumulated in the system but this is of no concern and will quickly clear as the engine starts to warm up.
If however, the vehicle is always exhausting white smoke, even when the engine is warmed up, this will be caused by coolant entering the combustion chambers i.e. a leaking head gasket. If there are signs that the head gasket has failed switch the engine off, do not drive the car as further use will cause more damage. Have a head gasket leak test completed immediately with your local professional garage.
Too much black exhaust smoke?
If a vehicle is expelling to much black smoke it’s a sure indication that either there’s too much fuel or there is not enough air in the fuel/air mixture.
For fuel-injection vehicles, the sensors and injectors should be checked to ensure they are operating correctly and hoses related to the turbo checked for splits or leaks as either of these issues will likely cause too much fuel to be delivered and lead to a rich air/fuel mixture and black smoke.
Air filters and all other air intake components should also be checked, if clogged they will be a restriction on the air intake again leading to air in the fuel/air mixture
Too much blue exhaust smoke?
If a vehicle is exhausting blue smoke this is a bad indication that the engine is burning oil and should be inspected by a professional at the earliest convenience to determine the fault.
Most common reasons for such an issue are…
- The engine has become worn through old age or excessive heavy driving habits leading to internal oil leaks.
- Defective or worn piston rings are allowing oil to enter the combustion chamber. If this has occurred the vehicle will also be experiencing loss of power, especially under load.
- An incorrect oil used during the last oil change or poor quality oil which is too thin is causing the oil to escape into the combustion chambers through the seals.
