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!

Really informative, walked you through the diagnostic and fault finding. Explained his reasoning.

I would definitely recommend and I will be using him again without a doubt.

Thank you Leon.

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.

Brilliant brilliant service, the transparency is was made everything simply lovely, I got to better understand my car for the very first time and we talked through the diagnostic report together, non of this car goes to the back and you get piled on with quotes without a clear view of your own diagnostics! U would happily recommend any day!

Adrian was absolutely brilliant from start to finish. His communication was spot-on — friendly, helpful, and professional throughout. He explained everything clearly and made the whole process really easy. The quality of his work is amazing — my car feels incredibly smooth after the carbon clean, like it’s running better than ever. You can tell he really takes pride in what he does.

Highly recommend Adrian to anyone thinking about getting their car carbon cleaned — top guy and excellent service!

Adrian offered a simple and efficient service, from initial contact to completion of the job.

I was booked in quickly and had clear instructions ahead of Adrian’s arrival. He kept me up to date with his ETA on the day.

Adrian showed and explained everything that he was doing, and how the process works. He explained all of the engine codes and diagnostic figures.

Would recommend and will use again in the future
