The Valve cover gasket could be leaking, then oil drips onto the exhaust manifold. Our E46 had this problem. Blue smoke would come from the hood and wheel wells when the car was stopped at a light. I don't know about the E90, but the VC gasket failure is common on the E46. It is a relatively easy fix and BMW only charges an arm for it.
