Moin, I need your help with the diagnosis. I changed the condenser of the climate about four weeks ago and had to remove the fan for this. I was extremely careful with all cables so that I would not break anything. After everything was assembled again, I connected the battery again and started the engine. It then stuttered just in front of it, the fault lamp for the electronic throttle went on and then it is already dead n. I had forgotten to connect the suction tube pressure sensor again, so the plug, the vacuum hose sat on it. Since then it has not been reproducible so that (in my opinion) the motor control again and again quite extremely throttles the power. This is expressed so that, e.g. in the third gear straight ahead at approx. 2500 revolutions can hardly accelerate, the motor tortures itself really high. And a second later the full power is there again. Dependent, even full or partial load does not seem to matter. Otherwise the engine runs very quietly, without any jerker. The throttle valve was overhauled at ecu four years ago, cooling water sensor is completely new, BPR is new. Errors are unfortunately not stored. Does anyone know which sensors are installed in the area of the fan so? Maybe someone knows the error and can help me there on the jumps.
