2004 BMW X5 Question: blue smoke
BMW have a bulletin regarding a Check Engine Light coming on and or rough running attributed to a PCV hose problem. B11 202 05, but I don't think this is your problem. Things to ask are is your car burning oil due to high mileage, not frequent enough oil changes or incorrect oil grade or specification. Oil smoke out the tailpipe as you describe sounds like valve guide wear or valve guide seal wear. - patrick mannion
