Engine was quite restless, I registered myself and paid for myself, drove bar – mark on it, Kaufvetrag with exact KM stand registered, and mentions that it gives off extreme noises at short back and forth, and no test drive was possible !!!! After exactly 51 km drive after i ch was at home, the engine no longer jumps at !!! According to ADAC meherere defects according to error message device , but cause that it does not run is gasoline pump , estimate 280-, !
