    does terraclean / hydrogen carbon cleaning work?

    My car has hit 70k and the warranty runs out next month, the car has a misfire/stutter under light load and all the symptoms point towards carbon build up on the intake valves.

    Audi won't fix this properly apparently so the choice is £400+ at a specialist to strip it down and fix it or spend £99 and have a company like enginecarbonclean do it...they pump in hydrogen and it reacts with the carbon and cleans it...allegedly.

    Thoughts?

    Yet to see anything definitive on this. Not a single before and after that involves pictures.

    They way to sort it is walnut blasting at £400+. Or water & meths injection can help keep it at bay but not really fix it by the time it causes misfires.


    On the other hand is a punt at £90 worth the chance it might work....

    You are the only one to answer that.

    If it's a TDI then EGR block&delete and depending on your car an oil catcher, these can help reduce build up.

    I had a carbon clean for £99 when I first bought my wagon, didn’t seem to do anything really. Decided to have a proper walnut shell decoke a few months ago and that did make a big difference. Well worth £350 with the ultrasonic injector cleaning included. Car feels much smoother and more responsive :thumbs up:

    I don’t think terraclean or carbonclean can do anything as good as that!
