F5ECC Team

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

Simply the best regular maintenance for your petrol, diesel, LPG or hybrid vehicle of any age and mileage – identify and resolve issues, restore fuel economy to save money on fuel, restore performance, pass MOT and avoid future repair bills

Our expert and friendly service has been awarded the covetedย Which? Trusted Trader of the Monthย awardย twice.

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

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

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.ย  Suitable for soot and oil blockages and on a maintenance basis to avoid residual ash accumulation causing regeneration issues.

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.ย  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.ย  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.

After a narrow emissions fail at MOT for our 9 year old Landrover Adrian was able to fit us in on very short notice. Booking was simple, and he arrived bang on time. Great customer service throughout, happy to advise and explain not only what to expect but also how to keep cars in best possible shape between visits.Would thoroughly recommend on every aspect of both service and results. (And yes, the car passed its retest)

Was great to see Adrian again to perform a carbon clean on my Range Rover sport and on my wifeโ€™s Ford kuga. Both are beautifully quiet once again and restored the power again again. Always quality work and everything explained as always. Will see you again in another 20k. 👍👍

Just had my car completed with this company and I found the service to be friendly and professional. I was given clear information on the process beforehand with good instructions on what to do to prepare the car. The service took just under and hour and my vehicle was treated with care and carbon cleaned as requested. I was not expecting a night and day difference but got a more responsive car and a quieter engine. My car also had a known miss fire and even this greatly decreased. It is definitely worth a go especially if you have done many miles and my direct injection engine needed it. I also got diagnostic read outs showing was healthy aside from the slight misfire. 5 ✨✨✨✨✨

Adrian was prompt on time and very knowledgeable, the cleaning process takes around 45 minutes with a free engine check service for codes and possible future problems that could be occurring.Now before this clean my car was running rubbish i must say and now after the clean it's like brand new, no dipping when I accelerate now smooth idle and no more nasty smells when on stationary tick over.So if your car is running rough, smelling and not performing well, then give Adrian a call, he will come to you.😉

Really good service had a dpf service light come on my Mitsubishi outlander, have had this happen 3 times over 3 years, previous dpf company just cleaned it and not looking at what could be causing the problem, F5 engine carbon and dpf clean, looked for underlying problems for why it was happening, found that the oil level reset had not been done after an oil change and was causing it to partially block dpf as could not regen properly, after resetting the code that came up and doing a full dpf clean, car is now running a lot better than it was and feel more confident that the problem will not reoccur, excellent company and great staff who talked me through everything that was happening and what needed to be done, would highly recommend

I called Adrian in to investigate a DPF issue on my 2014 Astra 2 litre CDTi. The car was attempting DPF regenerations every 30 miles which were unsuccessful leading to a blocked DPF warning message which a previous garage had cleared by doing a forced regeneration. Adrian diagnosed a faulty coolant thermostat which caused the engine not to reach the required temperature which would allow a successful DPF regeneration.I eventually found a garage who would change the thermostat. 2 other garages, including a Vauxhall specialist, told me it would not fix the problem and wanted to re-diagnose the issue.After running the car for 3 weeks with a new thermostat, the car now reaches and stays at the correct temperature and successfully performs DPF regenerations at the correct intervals.I have learned a lot from Adrian on how DPF's work and conditions for successful regenerations.I also had an engine carbon clean and the car is running perfectly.Highly recommend Adrian for Carbon cleaning and to diagnose engine running issues.

Great company, i have an old Peugeot Expert which has had DPF problems for ages and been in and out of garages with no solution, Leon diagnosed and identified problems within minutes and during cleaning that had obviously been missed. DPF flushed and what a difference. Great comms and on time. Experts in their field so can recommend them with confidence.

I contacted Adrian after some issues with my car for a few months. Arranging an appointment was easy and coming to me was a great help. He spent the time looking at the diagnostics and explaining what he found, and what he had done to try and rectify it. He left me confident in his assessment and the price he quoted was very reasonable for getting such an expert assessment of the car.

Really happy with the service from Adrian at F5ECC, my car was having issues and running really poorly. I decided to ask for Adrian's help. Adrian moved mountains to squeeze a booking in for me within a couple of days. when he arrived he explained every stage of the process to me in detail showing me all the data on the computer. I now have a car with no check engine light, running so smooth and quiet. More MPG. Just like having a new car. Many thanks Adrian and I will certainly use you again in the future, probably as a pre-service preventative measure. Superb customer service.

Prevention is better than repair!

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.
