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.

I had my Mercedes SLK carbon cleaned by Ciaran last Saturday and was really impressed! He was old school customer service at its best and went through every single part of the process with me and also took time out to give me some general tips on looking after an older engine. The results where impressive and the car definitely runs much more smoothly now.

Had james at the house today for a carbon clean on my rs4 v8 read lots of mixed reviews online about cc cleaning but thought I'd give it a go anyway took about 40 mins all I can really say is wow what a difference in throttle response and general running of the car couldn't tell you if fuel economy any better as never check that being rs4 it drinks what it needs james is very professional and a great lad to chat to good knowledge of what he's doing and even gave great advice on my crafter van thanks again james for awesome jobSean Birrell
Had my passat, and father's passat cc (both 2.0 tdi 140 hp) remapped yesterday morning by James. I was glad to hear that the Egr could be deleted without having to buy the delete kit or having to get my hands dirty fitting it. We were happy with the increased performance and throttle response.. Very handy for overtaking. My father used to own a Mercedes c320 3.0 cdi and after buying the passat cc he felt the car was sluggish compared to his Merc. After James remapped his car first he took it a test drive and was happy that the car had more power.
Would recommend Jptuningborders to anyone who wants that extra power or more throttle response for overtaking. Thanks again.

Just had my Audi remapped. Cannot fault the service provided by James. First enquired about a remap on Tuesday, the car was remapped on Thursday!!!! Very quick service and was able to fit into my busy schedule by working after 5 � My Audi passed the health check beforehand and was remapped in about 15 minutes! It now drives smoother, pulls through every gear much better than before and has insane amounts of power whenever required � Don't hesitate to go with James for a remap, won't find better customer service in Britain. My only regret is I didn't do it months ago �
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.
