Cannot praise Adrian enough for his services and support. I had an engine fault light come on the car suggesting a dpf error. I contacted Adrian for a dpf clean and he was very honest to say he didn't think I needed one. I booked in to have an engine clean and diagnostic and replaced the dpf sensor myself. The communication from Adrian prior to the visit was excellent, checking all was OK and advising on arrival time. On the day Adrian turned up on time and carried out the engine clean sending me the diagnostic reports. Afterwards the car def runs smoother, over the last 1200 miles I have had another 3mpg which doesn't sound like a lot but bear in mind it's an old merc that's done 106k so going from 44 to 47mpg and 33k miles a year saves me 48 gallons or 217 litres of fuel which means the engine clean has paid for itself in fuel usage alone after 4 months driving and I expect the engine components to last longer. Def something I will have done every year and would strongly recommend to have done. Apart from the clean the support and advice from Adrian was excellent and would def recommend him and his company to others. Thanks again Adrian 👍

Excellent service from Adrian at F5EEC. My Mazda CX-5 had ‘fluttering’ symptoms and some power loss over the last couple of months. Adrian arrived promptly and discussed the process in detail.very polite and knowledgeable.
Took the car out after the clean and feels smoother with no ‘fluttering’ felt, a noticeable change. Recommend 👍

I've used F5 Engine Carbon & DPF Clean on two occasions with excellent results. One car was struggling to meet emissions standards for an MOT which sailed through after. The second car was a routine clean but I was extremely pleased with the performance and MPG gains.
Adrian's is technical knowledge is outstanding offering advice on the services he provides and whether they will meet your expectations and requirements.
The detailed analysis of your cars ECU fault codes is a great addition and highlights area of concern before they become a problem. He also offers advice on how these can be resolved.
Adrian is professional, arrives on time and puts you at ease through the entire process. I would thoroughly recommend the services he provides. Give him a try it may save you a fortune in the long run!!

A fully insured and IMI certified mobile service direct to your door across the East and West Midlands and beyond...

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.
