yes I have since had adaption reset on a mb star and fuel trims were reset but on test drive afterwards short fuel trim is adding between 12 and 18 % and then starting to add long fuel trim obviously because the short is so high .
I'm sure from memory on the mb star the code p201c related to mixture adaption too rich which is confusing me as surely if it was it would be taking fuel away the only other code was p2058 lambda control but I cant remember the rest of the terminology
thanks lee
