Mini Cooper S Misfire on Cylinder 4

⭐⭐⭐⭐⭐ ‘What a difference this has made to my car’s performance!

It’s positively a joy to drive again. Very responsive and more fuel efficient.

I found Adrian approachable, helpful and informative.’

Misfire on Cylinder 4 Mini Cooper S (2007 – 91,765 miles)

Reason for booking in…‘The car is very slow to respond/lacks power when trying to accelerate, when going up/down gears when over taking slow moving vehicles.’

Initial inspection of the Mini Cooper found no obvious issues in the engine bay with no excessive rattles and shakes, but a tell tale bass purr from the engine from the carbon present.

Initial code read found… cylinder 4 combustion misfires

Live data for the Mini Cooper S showed all values on the day looking acceptable with no misfires at idle, temperatures as expected, etc.

‍On with the Engine Carbon Clean for the Mini Cooper S and It soon smoothed out, quietened down and by the end it was quiet, smooth and responsive again.

❗ The owner can now start to run better fuel and see if the misfires return. If so then start looking at the spark plug, coilpack and injector as next steps.

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.
