F5 operative turned up promptly and started carbon cleaning while checking live diagnostics which uncovered a fault that 3 other mechanics had overlooked, he advised a cause of action which has resolved the problem, extremely grateful for such an excellent service, reasonable too. Highly recommend.

Had a carbon clean done on my car today and I’m really impressed with the service. The whole process was explained clearly from start to finish, so I knew exactly what was being done and why.

The car already feels smoother to drive and more responsive.

Really clean setup, well organised, and great customer service. I’d definitely recommend this to anyone wanting to improve their engine performance and look after their car properly. I’ll 100% be back again in the future

A fantastic service from an excellent company.
After 150,000 miles my BMW was running a bit rough. The engine clean has the straight six running as smooth as butter.
I could not be happier.

Just bought (or about to buy) a used vehicle?

Have a warranty? Use it!

You never know what you are going to find. Whether a private purchase or from a dealer we can help you identify underlying issues.  Although there may be no warning lights present, that doesn’t mean there aren’t any issues present.

We will help you identify underlying issues with our live data diagnostic investigation service.  We provide you with reports and screenshots you can use with any claim you need to make.

A typical practice from sellers is for codes to be deleted prior to sale so we would recommend putting a few hundred miles on it before our visit.
Assuming there are no significant issues then the Engine Carbon Clean is ideal to get it running smooth, quiet, responsive and economical again.

Vehicle Inspection 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.
