I love my “diva”, but she makes me crazy :-(……need your help!!!!

Hello you guys, I really need your help from someone who knows about this kind of car guuuut 😉 I drive my Spider 939 now for 8 years and this car costs me the last nerve. There was not a single year with this car without problems! Currently I have the following problem: My engine light went on and off, on and off, on and off…. However, the car drove perfectly. Then he went after a few days into the “emergency mode” and I brought it to the workshop. This time to the workshop of my trust and not to Alfa, because I have only made bad experiences so far. After reading the error, the error should probably be back at the control chain again. I had already had this again at almost 30,000 km koplett. Today I had to go to… the car went out of the tacho. To make it short, the sensor has been exchanged for the 3rd time now. After that I was able to drive again about 1 week and now the engine light is again to drive again. Today I already had the Gau…. the car went out! I did not find this problem again, but I did not know this problem again in the last time. I remember.
