Hi Had the same problem for almost a year. When I parked with the nose up even just a small amount it needed to be pumped. The problem was a small crack in the filter housing that the dealer replaced. The crack could not be seen but the dealer was aware of the problem from previous customer complaints. Changing filters did no good whatsoever. Dan
