If it only smokes right after coming off idle, it could be an indication that the oil seals in the turbo are giving up. It could also be the valve stem seals. My '02 suffered the same thing (from both causes) and actually ran strong for 2 1/2 years that way. I eventually spun a rod bearing, however I put my car through extreme abuse (track time, towing)
See if still does it when your oil level is correct, or if it consumes a lot. Mine needed a quart about every 12-1500 miles.
If you just bought the car from a dealer, I would see if they would address the issue. Neither problem is that difficult to fix. I would have them start with the turbo, since that is a more costly rebuild, and the most likely cause.
