Help!!! My cadet gets no more AU!!! Hello, I was friendly, because I need an AU. Well, until now it was not a problem, but just went from a certain speed of the CO values to beyond good and bad. The engine has not been running so nice since about 4000km, unfortunately I did not find the Threat any more. But does not want to repeat everything. They have read out the Multec, and all systems worked according to the mechanic perfectly…. n “Kat broken”, another babbling something of “outlet valve broken”. I assume now that the cat is whole, and it is related to that the engine does not run so perfectly anymore. Someone’s idea what I could change / look at nocxh?
