Hello Omi friends, have had a problem with the Motronic lamp, engine 2.0/116hp_ X20 SE since the cold days. Since then, this is going on and off after hot running phase. I had the fault memory read out in an Opel workshop. As a mistake these indicate: crankshaft sensor. Can it be that this sensor was damaged by the cold weather, temper. partly 17 degrees minus? Vehicle was standing in the open carport, unused for a week. Now the workshop offered me an original, or one This is of course much cheaper in terms of price. At Autoteile24.de, this costs around 70 €, from Hella. My question is: 1.) it may be that the sensor has damaged due to the cold, possibly sweat water at this temp., or are there other reasons? Have already treated the plug with contact cleaner, without success. 2.) Buy brand goods or cheap offer? Thanks already for your help and trouble. E. Helmut
