Hi there:

It’s very difficult to tell you for sure what might be wrong with your vehicle, as we’d need to be there to complete a car is smoking from exhaust inspection. However, when it’s cold, sometimes you might see a "smoke" come from exhaust; when actually is condensation from the engine exhaust reacting to increase humidity during cold and rainy conditions. If your car is running OK and you don’t notice any error or warning lights, you should be OK to continue driving.
