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.

Had my Range Rover sport and Mercedes e class re mapped this morning. What a sound guy, explained in detail what it exactly entailed and the difference too both vehicles is superb. The response and pull is unbelievable. Would highly recommend too anyone, great service, very professional. Cheers, will be back soon for the carbon clean.Martin Retter
So today I had my 2.5 petrol t4 carbon cleaned I was lucky enough to win this service for free. Must say I have honestly was not sure if it worked but as it was free decided to go
For it. Must say I am impressed has not given me an extra 100bhp but has definitely made a difference to how the old girl drives. Seems to be a lot smoother and pulls nice. And also seems to have stopped the little bit off smoke I get on start up. So far so good let’s see if I get better mpg out of the full tank I just filled up with. Really impressed with Matt the agent I met nice guy talked me through the whole process. Definitely considering getting my other vw t4 2.5 diesel van done

I was told by a local garage that they thought my EGR valve and DPF were dirty on my car. In 5th and 6th it would judder and lose power when accelerating. A local garage told me it would take 3 hours work to clean these before they start looking at changing the EGR!
When I got home i looked into carbon cleaning and found this website. After a quick query I was soon in touch with Cristian who was confident I needed a stage 3 clean on my car. From speaking to him to having him on my drive working on my car took no time at all.
On time, polite and very informative he got to work straight away and carried out his magic on my underperforming Astra. Once he had completed the clean I took the car out down the dual carriageway and it was back to performing like it was new again. The juddering in 5th and 6th had completely gone and the car seems a smoother ride.
I'd recommend anybody to get their car carbon cleaned before they went to the garage.
Had my wee car carbon cleaned today must admit I was a bit sceptical at first but glad I opted to get it done James was very polite and professional talks you through everything he is doing , went for a run in the car tonight and it is a lot quieter ,runs smother and would in my opinion have more power thanks James �

Husband has just had James remap our Renault Trafic van. He reckons the trip from Hawick to Clovenfords was a revelation, the van pulling cleanly and smoothly, with acceleration uphill even in 6th gear. What a difference you have made to this van James, well done man! You have made a mundane workhorse into a pleasure to drive!
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.
