Servus, have a question….or several of my Omi since I cleaned the throttle valve very unround. MKL goes on more often, but again. Oil filter of the 16V in the crankshaft venting is already installed. Plug all pulled, cleaned and plugged more often. Liquids all in order. Tubes all clean and flasheblank. Intake tracked with start pilot sprayed, no fluctuations. Today I found that my Omi from the oil filling opening “qualts” after I opened them. I still have the assumption that it is the oil spills which are led into the throttle valve. Now my first question: when I read the fault memory I have to pre-clamp the battery? how long does the control device notice the error messages? I can also read the error memory when the engine runs (does not have an ODB device) Office cling method… My second question: does a defective, undichter exhaust (end sound silencer) to the engine run noticeably high? 16 error code – no error rate – 24 – no voltage change of the battery.
