Salute young, I have the following problem with my audi 80 b3 1,8l bj. 87. Before: Oil pressure is ok. Oil is enough in it. Display on the measuring rod center. Oil pressure switch (black and white) change. Problem: If I switch cl. 50 (motor start) lights my oil warning lamp permanently. As if the pump was defective or too little oil in it. But unfortunately both is not the case. When acceleration sounds then also the warning tone for too little oil. If I plug off both oil pressure switches is logically the lamp off but when the acceleration is done the lamp and the warnon goes on anyway. Sometimes for half a second… sometimes up to 10 seconds. But the pressures are all ok. I really don’t know any more…. about help or a tip I would be so grateful. Thank you, Gruss Matthias
