Hello together, for about 1 week my wife and I are proud owners of a Volvo 850 2.5 20V from 1994. Have received this from my father-in-law. Of course, he has some flaws, which I have partly already fixed with my father-in-law already, or will fix (gear wheel km counters), dampers behind (nivomates) etc. However, we have at least at first bited our teeth on one problem. The tank indicator does not work. When the ignition is activated moves si c the needle around about 2mm (that seems to be normal too), but the level is not displayed, the needle remains below. What we tested: Test AI (Buckle A-7, Mode 3) – Tank clock goes to half full, so nothing seems to be defective in the AI. Tank clock-specific errors could not be turned off in A-7 either. Afterwards we changed the tanker (my father-in-law has a second 850 standing with him, where the tank indicator worked). Unfortunately the not ts changed. Now we’re a bit perplexed, even the search function here in the forum didn’t get me any further, because there was usually a mistake in the AI or the tanker in the similar topics. My question would now be: I have read in the meantime that there are two tankers, once the separate one (which we exchanged), and a second one that is combined with the petrol pump. Is that true? Or is that only the case with the V70/XC70? What else could it be? If the wiring were defective, I would have gotten a mistake, too, wouldn’t I?
