Iv had the pleasure of having 2 Carbon cleans from both Adrian and Mark. Both lovely gentlemen and you can tell they love what they do. My car failed on emissions and this helped me get the car through the test, and at the time, I REALLY needed a pass because I couldn’t get anywhere. These guys saved me. Not only that, it’s a lot cheaper here compared to other places also. Thank you so much and look forward to seeing you in future endeavours.

Amazing service, didnt expect too much but totally blew mind, performance was increased, not much but I'd recently had a new turbo, so didnt expect much, as for mpg, I was expecting afew mpg here or there, but in truth it blew my mind, I have a 2005 mondeo st estate with 162k on the clock, and it went from 45.4 mpg on motorways to 68.8, posted video as proof, should highly recommend

Couldn’t ask for better service. Had a carbon clean done this week on my partner’s Astra. Adrian responded very quickly to my initial query and got us booked in for the next day. He was very thorough and explained everything that I wasn’t sure of (my knowledge on cars is awful). He provided the fault codes and the live engine data and gave great advice about how to fix the current issue we were having with our car. The car runs very smoothly and is finally lovely to drive again, wish we’d done this sooner. He was very friendly & polite which put any worries I had at rest. I wouldn’t go anywhere else. Thank you so much!

"I recently had F5 Engine Carbon Clean work on my three vehicles—a 2012 BMW X1, 2007 Jaguar XJ, and 2005 Audi TT—and the results are superb.
What really sets them apart is the comprehensive diagnostic work they carry out as part of the service. On two of my cars, the diagnostics highlighted a couple of underlying issues that I was completely unaware of. Because these were caught early, I was able to get them resolved alongside the carbon clean, which has made a massive difference to the overall performance.
All three cars now idle more quietly, feel sharper, and pull much more smoothly. It’s rare to find a service that combines deep technical knowledge with such tangible results. Professional, thorough, and highly recommended!"

Highly recommend!!
Excellent service, Adrian turned up on time, had the carbon clean and my car was diagnosed with a DPF issue so had a follow up appointment by Leon to sort out the issue and as I said before the car is much improved MPG seems back to normal and the car is running great.
Many thanks ????????

Steve came out to give our DPF a full clean on our bmw 2 series the before and after results are incredible. More power better MPG and overall the car feels way better to drive. He showed us the before and after statistics. We are definitely getting him back to do a carbon clean

Sticking Turbo Symptoms

If your vehicle is suffering with code for turbo overboost (P0234), turbo underboost (P0299) or other sticky turbo symptoms then our service is an ideal starting point.

Sticking Turbo symptoms can manifest themselves with lack of power, or jerky power delivery, coil lights, engine management lights and limp mode issues.  The cause will usually be down to:

Sticking Turbo Causes

Bottom line is an Engine Carbon Clean might help depending on what the issue is – we won’t know until we try.
 
We have done plenty where the issue has purely been down to carbon build-up causing sticking vanes or just restricted airways, but have come across quite a few where the metal surface has pitted when its been in contact with the carbon too long and although the carbon is removed then the surface is no longer smooth so it can still stick.
 
On occasion there can be an issue with the turbo itself (mechanically/electrically, e.g. the N75 valve, actuator) or perhaps the boost sensor, etc. which is why until we plug in the diagnostics to see if anything obvious or do the clean then we won’t actually know if it cures the symptoms until we try.

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. 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 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.
