"I recently had F5 Engine Carbon Clean work on my three vehicles—a 2012 BMW X1, 2007 Jaguar XJ, and 2005 Audi TT—and the results are superb.
What really sets them apart is the comprehensive diagnostic work they carry out as part of the service. On two of my cars, the diagnostics highlighted a couple of underlying issues that I was completely unaware of. Because these were caught early, I was able to get them resolved alongside the carbon clean, which has made a massive difference to the overall performance.
All three cars now idle more quietly, feel sharper, and pull much more smoothly. It’s rare to find a service that combines deep technical knowledge with such tangible results. Professional, thorough, and highly recommended!"

Highly recommend!!
Excellent service, Adrian turned up on time, had the carbon clean and my car was diagnosed with a DPF issue so had a follow up appointment by Leon to sort out the issue and as I said before the car is much improved MPG seems back to normal and the car is running great.
Many thanks ????????

Steve came out to give our DPF a full clean on our bmw 2 series the before and after results are incredible. More power better MPG and overall the car feels way better to drive. He showed us the before and after statistics. We are definitely getting him back to do a carbon clean

Highly recommend this company.

Van was very sluggish and noisy so thought I would try a carbon clean and diagnostics.

Adrian was very quick to respond to my enquiry and managed to fit me in the same week. Adrian was incredibly knowledgeable and ran through the diagnostics with me and answered any questions I had. Carbon clean was quick and effective.
After the carbon clean the van drove a lot better and pulled through all gears very smoothly.
Well worth doing.

I rang Adrian after using him in the past and he got me booked in really quick, came out with constant updates on arrival time so didn’t have to sit around waiting. Did all the checks on the car then explained everything as it was being done, didn’t mind answering any questions asked. Mentioned a slight vibration and after it was all done the vibration was almost non existent sounded loads better and was driving in my opinion better. Really good job was very pleased and top man Thanks

All round a very impressive service.There is a noticeable improvement in my 100k mile diesel, it runs more smoothly and hopefully will have a better mpg.
Adrian also took time to examine a number of engine fault codes, listing them for me for further investigations.
Thank you!

Cant be happier with the service on my 115k mile 2013 Hyundai i30 1.6CRDi (Diesel). Quick responses on email/whattsapp. Open communication on how their van/machine needs to be setup and how to prepare your car. The clean was quick and Adrian was highly informative in the diagnostics with whats normal and whats irregular (luckily nothing major was found). Also told me about how the cleaning process works which was interesting. After the clean (~50mins) the car has an increase in performance, throttle response, a smoother operating engine with less vibration and improvements in the mpg (~10mpg) which were all previous problems I had encountered. Could not recommend them enough as it now feels like brand new and will certainly be using them again when the time comes around (~25k miles later as suggested) or if I were to change 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.

From 55mpg to 72mpg! Perfect service couldn’t ask for more, the car runs smoother than ever, start to finish was given clear honest advice and help. Booked the carbon clean and diagnostic was kept in the loop with everything and given a detailed report of everything, really clear communication throughout. Would highly recommend.

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 u003cstrongu003ewithin the vehicleu003c/strongu003e 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.
