Hi, I just bought a 1.4 Lupo today and was driving it home quite the thing and the oil warning light flashed on, so I stopped the car, switched everything off, got out and checked the oil and there was plenty in it. So I continued driving, and it flashed on again, so I repeated and it was fine, so I continued driving again, but not going above 2k revs this time, and it was perfectly fine, the car doesn't make any strange sounds while driving, has anyone head of this before? Should I be worried?
