Had a carbon clean which I am happy with, although it was expensive, also the terms and condition that are handed to you on the invoice after work is completed is unbelievable, if you were having a DPF clean especially I would urge you to ask for these before any work is done on you car.

Originally wanted a dpf clean but after speaking with Adrian, he recommended a carbon clean of my 2014 Mercedes sprinter. Turned up on time and with all the kit. Job done within the hour with some issues identified (new thermostat needed being chief). Almost immediately, my van runs smoother and quieter. Very happy with the results and equally with Adrian's no nonsense knowledge of the task and professionalism. Would definitely recommend you speak to him before anyone else.

5-star advice from Adrian at F5ECC. He provided some brilliant free advice and instead of just trying to sell me a service, he gave me some incredible technical insights for my Audi A3 that saved me from a costly and unnecessary repair. He clearly knows these diesel engines inside out and is a total professional who puts the customer first. When I eventually do need a carbon/DPF clean, he’ll be the only person I call. Highly recommended.

Adrian came to a carbon clean on 2 vehicles . Kia Sportage 1.6 crdi and a Mercedes A200 diesell 2.1. Kia was having no issues just was a regular clean as I have used Adrian for several vehicles and understand the benefits of a clean. Again I noticed better performance and start up. Mercedes had starting issues and inconsistent running. After the clean it was more responsive , noise from the exhaust valve seems to go a way and not present anymore . So a better running Mercedes also. To be clear the Mercedes when warm would bit and not restart so definitely improved performance and start up issues. Thank you . See you in the summer for the Renault Clio clean .

I had my 2016 Ford S‑Max 2.0 TDCi carbon cleaned, and the difference has been impressive. My average MPG has gone from around 41 to 45, which I honestly didn’t expect, but the improvement is real. The engine also feels a touch smoother on acceleration, especially when pulling away or overtaking.

Professional service, clear communication, and results that genuinely make a difference. Highly recommended.

What Causes Carbon Build-Up and Why Your Engine Needs a Carbon Clean

All petrol, diesel, LPG and hybrid engines create carbon as they burn fuel. When the engine is new the levels are low so everything runs smoothly, quietly and efficiently. As the miles add up incomplete combustion becomes more common and carbon deposits start to stick to internal parts. This can happen from around 10,000 miles.

Why modern engines suffer more with carbon

Newer engines are built for performance and low emissions which means they rely on more complex systems. Features such as direct injection, swirl flaps and tighter tolerances make them far more sensitive to dirt. Even with cleaner fuels carbon still builds up over time, especially on cars that do short trips or stop–start driving.

Carbon Clean for engine

How carbon build-up affects your engine

As carbon gathers inside the engine it becomes harder for it to run cleanly. To keep going it starts using more fuel which increases emissions and creates even more carbon. Over time you may notice:

Why a carbon clean helps

A professional engine carbon clean removes these deposits and helps the engine breathe and burn fuel properly again. Most drivers notice smoother running, improved throttle response, better fuel economy and lower emissions.

Regular cleaning is a simple way to keep the engine healthy and avoid unnecessary wear and tear.

Carbon Cleaning FAQs

What does an Engine Carbon Clean do?

Keeping your engine cleaned on a regular basis helps prevent issues such as DPF issues, MOT emissions failures or sticking turbos. An Engine Carbon Clean is great at cleaning up the back of a turbo, combustion chamber, injector tips, pistons, cylinders and cats to get a vehicle running smooth, quiet, responsive, economical and emissions friendly again.

Can you carbon clean a petrol engine?

Yes. All hydrocarbon engines create carbon build up depending on the mileage, driving style, journey length and fuel quality used. You can clean petrol, diesel, LPG, hybrid or anything else such as methane.  Not just cars and vans, but we also work on boats, tractors, tanks, generators, landfill engines, anything really.

What are signs of carbon build up?

Typical symptoms include a decline in fuel economy, noisier engine, increased vibration, sluggish response and smoke/emissions levels. As fuel economy and emission targets have got stricter over the years the engine components have been developed and added in order to keep the soot within the vehicle rather than passing it out through the exhaust. This then clogs up EGR valves, inlet manifolds and DPFs.

When should you Engine Carbon Clean?

If you have just bought a vehicle or warranty is due to expire then it is a perfect time to get it checked out and cleaned up. As part of your regular maintenance plan an ideal time is just prior to a service or MOT to help keep your vehicle running smoothly, quietly, economically and with low emissions. Most people are coming back for repeats approximately every 15-20k miles based on driving style, journey length and fuel quality.

Does Carbon Engine Cleaning actually work?

Yes it does and it is very good at what it does as long as the relevant pre-checks are performed to ensure an effective clean and critically it is done by someone who is properly trained, certified, with the right approach and equipment.
