Hi all- I've seen a bunch of past posts but haven't found the fix yet. When full my gauge reads "full". When empty (I ran it out on purpose) it reads about 2/3. When I bought the car the sender was corroded so i replaced it with the slk320 equivalent, about 200 ohms empty, 5 ohms full. Checked wiring per the shop manual, continuity good, no shorts or opens. Instrument cluster provides about .7v at the unplugged sender connector. So I replaced the instrument cluster- exactly the same result. With the fuel gauge inop, car won't complete OBD2 monitor tests (cat & evap)- so car won't pass N.Y.S. inspection. All because of a fuel gauge! Anyone with first-hand experience? Love trhe car, but... Any help greatly appreciated! Thanks, the Panman
