Booked in my Audi A3 for a carbon clean on the exhaust system due to symbols appearing on my cars dashboard. Craig explained in detail what the process involved and what I should expect in terms of improved performance and fuel economy once completed. After connecting to the cars systems to diagnose any faults the car was hooked up to the carbon cleaning machine. The whole process took about an hour from start to finish. Once behind the wheel the car immediately felt more responsive in both low and high gears with significantly less rattles coming from the engine especially upon start up from cold. The warning lights eventually disappeared once the system adapted to the clean. Total cost was £79 which is very competative compared to similar businesses offering this service. I will have no hesitation what so ever in having another clean with Mr Carbon Clean in 6-12 months time and would recommend to anyone to have it done from a preventative maintenance or performance perspective as it is significantly cheaper than the labour needed to replace damaged engine parts further down the line. read more
