Recently I have a strange behavior. If I drive constantly, i.e. evenly, e.g. 50km/h, then it is always easy to notice a jerking. As if I have short ignition oscillations. Also I have times that when starting the cold engine, it shakes strongly until it then runs after a few seconds round. Does also somehow indicate ignition oscillations. What have I done so far: All spark plugs renewed -> no improvement read out errors -> nothing saved All Verbr also switched off, like climate; light etc. -> no change. If you let roll, so clutch kicked and stand gas, is immediately calm. So comes definitely from the engine. Hmm should it be an ignition coil? Only which one? , how do I get that out. By the way, when accelerating I don’t have the feeling, because there would be something different. However, it can be deceptive. Now I need a clever tip Greeting Axel
