Hello people, now that I have been searching through posts here again and again, I have registered myself. Now to a problem that I have on my OM646. In idle the idle is usually easy, this can also be easily heard. If I constantly drive a speed and the engine does not run on load, this problem can still be observed. At my disposal I have an ANCEL AD310 OBD2. AGR (Pierburg) is new. If someone has an idea how to find out ka nn, where the “problem” comes from? There are no bugs in the memory, as well as I have already attached an injector cleaner. However, this has not shown any changes. – This should not be an invitation to discuss additives Please give me any advice! Thank you already in advance
