Hi all I have a Damon Astoria 3773 (2007)on a freightline chassis ESN 46587367 model is and I have a check engine warning light come on,I have taken it to my dealer who has put a laptop on it and it has told us the warning light is on because of carbon build up in the turbo to take it off and service it is an absolute nightmare I have been told you can add a addictive to the fuel (archoil ar6400-dmax) that will clean the turbo and then turn the light out,has anyone had this problem a got any advise.
