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.

Leon and Steve was very informative and answered any questions or concerns that I had especially DPF related. It has given me the necessary information on how best to pro-long the life of the DPF and hopefully prevent any likely costly repairs in the future. I would highly recommend!

This process makes an amazing difference to the smoothness and power output of your engine. It's well worth the investment and they are punctual and professional. Having it done annually would be a good idea.

Engine 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. It also 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.

What does DPF Cleaning do?

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

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 within the vehicle 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.
