F5 operative turned up promptly and started carbon cleaning while checking live diagnostics which uncovered a fault that 3 other mechanics had overlooked, he advised a cause of action which has resolved the problem, extremely grateful for such an excellent service, reasonable too. Highly recommend.

Had a carbon clean done on my car today and I’m really impressed with the service. The whole process was explained clearly from start to finish, so I knew exactly what was being done and why.

The car already feels smoother to drive and more responsive.

Really clean setup, well organised, and great customer service. I’d definitely recommend this to anyone wanting to improve their engine performance and look after their car properly. I’ll 100% be back again in the future
