⚠️ Vehicle not running like it should? Not as quiet, smooth, responsive, economical or emissions friendly as it used to be?

Here we have a Toyota Yaris 1.4d (2004 – 157, 046 miles) booked in for diagnostic consultation and Engine Carbon Clean.

ℹ️ The owner had booked us in due to the age and mileage, but especially to diagnose an intermittent power loss issue.

Initial inspection found no obvious issues in the engine bay.

Initial diagnostics found a glow plug heater circuit code and the culprit – Accelerator Position Sensor Circuit.

Live data monitoring showed decent values elsewhere, but coolant temperature would only get to 82°C and dropped rapidly when putting the cabin heating on – new Thermostat required.

‍On with the clean and it soon smoothed out, quietened down and by the end it was quiet, smooth and responsive again. The owner can now get the Accelerator Position Sensor issue resolved and replace the thermostat.

I found this organisation on Google. It had great reviews and the service which I required which was a carbon clean. I found Adrian very helpful and knowledgeable. While he was carrying out the service he explained everything to me and how it works. The car feels better now with it being more responsive and quieter. I would recommend Adrian and his company to friends and family if they required his services. Thanks Adrian hopefully see you again sometime.

This was my first experience with F5 carbon and DPF clean. I was a little desperate as I had been let down twice by a larger franchise company. Mark the technician managed to fit me in at short notice, what a stroke of luck for me I found Mark to be an extremely knowledgeable and professional guy. After running the diagnostic and clearing a few issues he managed to get my DPF working properly and able to do the regeneration process on its own so only charged for the diagnostic even though I had booked for a full DPF cleaning. I cannot recommend F5 enough it's a real pleasure to deal with them. All round excellent service. Thank you guys.

Adrian is a lovely fella, explained the process, carried it out well, clearly done exactly what it needed to do as I blew a load of stuff out the back when I drove it after. Will definitely be coming back in the future.

Steve arrived to give my Jaguar xfs an engine carbon clean. Presently on 107,000 miles. Explained the process and was obviously very knowledgeable about the process and expected outcomes. And he was a thoroughly nice chap.
The V6 in the xfs is a quiet, smooth, powerful unit and I was not sure of what improvements I would get. Well, I’m impressed. The power delivery is smoother, the engine even quieter and 6 mpg better to boot.
If you want to do one thing to maintain and improve your motor, then this is what you should do.

Leon came out to my car about a month ago. He was brilliant, he did some diagnostics, asked some questions and then got to work sorting out my problem. He was extremely thorough and I could tell he genuinely cares about providing a first class service. Fantastic!

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.
