Hello dear friends! Since yesterday evening the engine control light lights up! Also yesterday I was able to stop and switch off the engine, wait 2 minutes, tap area turn on again and off again. Then first ignition of the engine without any problems start again. Engine control light went off. This morning no problems with the ignition of the engine. There was also no unround motor run or detonator. After a short stop at a parcel transmitter, I re-ignited the engine as usual, again no problems of the engine and no lighting of the engine control light. We drove on a quick road and I had to speed up to 90 km/h, when I reached the city of Trnava I had to go down to 50 km/h and hold it at a traffic light. They stood on red. Then the engine control light went on again. Even after holding again, engine stopped, wait and engine restarted the engine control light remained on. I have the assumption that the Lambasonden are defective. Or what could it be? Sunday we want to go far away on holiday!
