I took out the dash recently and found the bulbs were in the wrong place minus one. I had bulbs in the auto box and engine (petrol only) warning lights for some reason and no bulbs in the fog light and low oil indicators. Anyway I decided id rather have oil warning light rather the cruise control indicator light and ever since I fitted a bulb the low oil warning light keeps coming on for some reason. I have checked the oil level and its just below max and it has good oil pressure (according to the manual). When it comes on it usually turns off within 15 min, sometimes sooner. Am i right to dismiss this as a faulty sensor or do I have bigger problems?
