So I bought my X reg Lupo last week, and the oil light keeps flashing and beeping intermittently. Oil and filter have been replaced twice in the last week and still the same issue. Oil pressure normal and filled up to the correct level, but it is still telling me theres something wrong! The car drives perfectly and the engine sounds normal, the light only seems to.come on when I'm pulling off at lights or whatever. Is this something I should worry about? Taken it to the garage and they can't see anything wrong with it?
