I rang Adrian after using him in the past and he got me booked in really quick, came out with constant updates on arrival time so didn’t have to sit around waiting. Did all the checks on the car then explained everything as it was being done, didn’t mind answering any questions asked. Mentioned a slight vibration and after it was all done the vibration was almost non existent sounded loads better and was driving in my opinion better. Really good job was very pleased and top man Thanks

All round a very impressive service.There is a noticeable improvement in my 100k mile diesel, it runs more smoothly and hopefully will have a better mpg.
Adrian also took time to examine a number of engine fault codes, listing them for me for further investigations.
Thank you!

Cant be happier with the service on my 115k mile 2013 Hyundai i30 1.6CRDi (Diesel). Quick responses on email/whattsapp. Open communication on how their van/machine needs to be setup and how to prepare your car. The clean was quick and Adrian was highly informative in the diagnostics with whats normal and whats irregular (luckily nothing major was found). Also told me about how the cleaning process works which was interesting. After the clean (~50mins) the car has an increase in performance, throttle response, a smoother operating engine with less vibration and improvements in the mpg (~10mpg) which were all previous problems I had encountered. Could not recommend them enough as it now feels like brand new and will certainly be using them again when the time comes around (~25k miles later as suggested) or if I were to change car.

Originally wanted a dpf clean but after speaking with Adrian, he recommended a carbon clean of my 2014 Mercedes sprinter. Turned up on time and with all the kit. Job done within the hour with some issues identified (new thermostat needed being chief). Almost immediately, my van runs smoother and quieter. Very happy with the results and equally with Adrian's no nonsense knowledge of the task and professionalism. Would definitely recommend you speak to him before anyone else.

From 55mpg to 72mpg! Perfect service couldn’t ask for more, the car runs smoother than ever, start to finish was given clear honest advice and help. Booked the carbon clean and diagnostic was kept in the loop with everything and given a detailed report of everything, really clear communication throughout. Would highly recommend.

5-star advice from Adrian at F5ECC. He provided some brilliant free advice and instead of just trying to sell me a service, he gave me some incredible technical insights for my Audi A3 that saved me from a costly and unnecessary repair. He clearly knows these diesel engines inside out and is a total professional who puts the customer first. When I eventually do need a carbon/DPF clean, he’ll be the only person I call. Highly recommended.

Adrian came to a carbon clean on 2 vehicles . Kia Sportage 1.6 crdi and a Mercedes A200 diesell 2.1. Kia was having no issues just was a regular clean as I have used Adrian for several vehicles and understand the benefits of a clean. Again I noticed better performance and start up. Mercedes had starting issues and inconsistent running. After the clean it was more responsive , noise from the exhaust valve seems to go a way and not present anymore . So a better running Mercedes also. To be clear the Mercedes when warm would bit and not restart so definitely improved performance and start up issues. Thank you . See you in the summer for the Renault Clio clean .

I had my 2016 Ford S‑Max 2.0 TDCi carbon cleaned, and the difference has been impressive. My average MPG has gone from around 41 to 45, which I honestly didn’t expect, but the improvement is real. The engine also feels a touch smoother on acceleration, especially when pulling away or overtaking.

Professional service, clear communication, and results that genuinely make a difference. Highly recommended.

This is my 2nd time Iv booked Adrian @ F5 to come and do me a engine carbon clean. He was a total professional from the start and even had all my details from my 1st visit , great communication pre visit , once here he talked me through the process and began his work , Iv been sent all the live data so I can see myself how all the internals of the car are running. Iv since had a run out in the car and it’s driving perfectly, I would recommend F5 to anyone considering having this done , il be using F5 again the future, thank you Adrian.
