Had this service done to our Mondeo Mk3 V6 today by a professional and very knowledgeable man. It took him around an hour to complete the clean and the results are amazing. With the age of our car I didn’t know what to expect but I can honestly say that it has given our car a new lease of life. The acceleration has improved immensely and it now feels more responsive and quicker than it did before the Engine clean.. well done and many thanks I now know where to come if I need another car doing. Worth the cost and will definitely recommend to my friends and family.

Adrian talked me through the engine carbon clean service prior to booking, so I booked the service and agreed a date and time, on the morning Adrian kept me updated on his ETA, and arrived promptly and on time. Adrian then got to work in a really friendly manner, keeping me updated on the work, and explained what I could and couldn't expect from the engine clean. Adrian ran a diagnostic test on my vehicle, and let me know what the test showed, then set about the engine cleaning. Adrian was very knowledgeable and had a great ear for the cars quirks. Towards the end of the engine clean it was a real difference in the sound from the engine, a lot calmer and quieter, and for its age seemed dto be purring great again. Adrian was brilliant throughout the service and I would highly recommend his services. All in all a great experience. Thanks Adrian. Will definitely be using them in the future.

Had an engine carbon clean done on my diesel car with 150k miles, and I’m really impressed with the results! The car runs much smoother after the cleaning. The customer service was excellent—kept me updated throughout the process and ensured everything was done to a high standard. Quality work from start to finish. Highly recommend!

Very experienced and reliable service found a problem with my thermostat that was causing the loss of MPG that was the initial reason for contact and having the carbon clean and diagnostic highly recommend there is alot of others but glad I chose this company to do the work well worth the money

Adrian arrived on time & explained exactly what the service consisted of. My vehicle then underwent a full diagnostic check to make sure that the service could go ahead. Once the checks were completed the carbon clean started whilst the whole time Adrian monitored the diagnostic readings on his tablet & when he was 💯 % sure that the system was cleaned throughout he told me to take it out to see how my vehicle was performing. Within a few minutes I immediately noticed the response whilst accelerating was noticeable straight away. My only regret is not of having this type of professional servicing done earlier. I fully recommend F5 carbon to anyone whose vehicle would benefit a clean and tune up.

Prevention is better than repair!

A booking with us is essentially a health check and detox for your vehicle.

Our IMI Certified service is about looking after the overall health of the vehicle, not just turning up to ‘perform a clean’.

Every booking starts with a health check, a diagnostic code scan of the entire vehicle looking for underlying issues (where applicable) and Live data diagnostics throughout to identify issues with injectors, fuel pumps, sensors, etc. which may not be logging errors.

We provide a MOBILE service and come to you anywhere across the East Midlands and West Midlands counties, plus we also cover Bedfordshire, Cambridgeshire, into East Anglia and Lincolnshire up into Yorkshire.

A dirty engine has to work harder against the dirt. To do this it uses more fuel, vibrates more causing more noise, shaking and lumpy running and increases emissions eventually causing MOT failure.

The more it shakes the more it will wear parts such as engine mounts, clutches, etc. so combat this before it becomes a problem.

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.

A mobile service to properly diagnose, clean and reset a DPF.  Suitable for soot and oil blockages and on a maintenance basis to avoid residual ash accumulation causing regeneration issues.

DPF Investigation and Clean Service

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.

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.

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.  Prevention is better than cure.

Most people are coming back for repeats approximately every 15-20k miles based on driving style, journey length and fuel quality.

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.

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, but will not clean up cold areas such as EGR valves or inlet manifolds and won’t unblock a DPF.

The only way to clean up these cold areas safely and effectively is a manual approach, e.g. strip and clean of the EGR or ‘walnut blast’ the inlet.

The Engine Carbon Clean is complementary to these manual approaches as they are targeted at different areas.

Cleaning up the combustion chamber cleans up the source of the dirt – this helps minimise future buildup in the EGR and inlet manifold as well as extends the mileage between DPF regenerations.
