Customer Question

My BMW330d (204HP on E46 body) has recently started giving out lots of blue smoke when cold. For a few minutes the exhaust is clear, then it becomes blue. After 5 minutes there is a quite a lot of blue smoke. After sometime, 10 minutes or so, the exhaust seems to clear and the blue smoke problem goes. If I restart the engine when warm, I cant see too much smoke. If I leave the car overnight, the blue smoke problem returns.
Ideas welcome!
