Hello together, I had reported here that my 190 diesel had said goodbye to the oldtimer meeting on the return trip. It just went off on the country road. After a short break a restart was possible. Again driving attempt fails after 2 km…… So the whole went until I was at home …..about 5 km. The tank sieve filter was closed. Black plague. No pollution in the prefilter…… nothing in the main filter. The engine probably still got minimal diesel. Could on this road however a The engine starts perfectly. Not too warm. Not too hot. Not too hot. Oil pressure perfect….. BUT: The engine runs very rough. Shakes. With a little more speed, the shakes after but the feeling that the engine is rougher. Engine definitely runs on all 4 cylinders. What can that be? Something scraped back with the rudder… ..? But what? The engine was never too warm. Oil pressure was always there. It was missing the spritt…. I would be grateful for ideas. Greetings Tegro….
