Overnight, condensation can collect in the exhaust which will turn into steam as your engine warms up.

One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant , it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust.

VW Passat with 70miles sends a puff of white smoke from the exhaust pipe while accelerating. Any ideas what the problem is? The car is a Passat 1. This is normal and is why exhaust systems have small holes at the rear of the muffler to allow water to drip out.

When the engine is again started the exhaust system will heat up evaporating the water causing steam. When you get this fixe also do the timing belt and water pump.
