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 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.

Went to see matt today at horley site, bought an 07 plate honda crv cdti yesterday so thought i would see how good a 3 stage carbon clean was! I can honestly say it has made a massive difference, the engine ticks over a lot smoother, and the acceleration difference is just incredible! Would highly recommend matt and his team, very polite, informative and professional service. Well worth the money in my opinion!!

Called Winston today to see if he could fit me in today very short notice I know but he was here within 2 hours. Talked me through the process and was very professional and a top bloke. I have a vw scirocco and it was a bit laggy on acceleration and the speed was down slightly but not anymore feels like a new car. Thoroughly recommend having this done.

Recently had my Passat tuned and it's absolutely transformed the car! Such a big difference through all the gears and has made driving a lot more fun!
I was originally gonna be travelling all the way up to Perth and paying over £300 so I saved a lot of time and money getting it done with JP as it took about 50 minutes and was a really professional job! With his diagnostic tests he also helped me find out what was wrong with my aircon so I can now order the parts and get that fixed! So all in all a big thumbs up �
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.
