Hi there. It really depends on the color of the smoke. If it is black then it can be a dirty air filter or a leaking fuel injector. If the smoke is white then it may have a leaking head gasket. If the smoke has a blue cast then the engine is burning oil which can be valve stem seals, or more commonly on this engine a bad turbo.

A diagnostic would need to be done depending on the kind of smoke that is appearing. If you want to have this looked at, consider YourMechanic, as a certified mechanic can come to your home to diagnose the smoke firsthand and help you make the necessary repairs.
