Question about 2008 Mercedes-Benz GL-Class
We bought mercedes benz 2008 gl-class 320. When driving occasionally out of exhaust comes white smoke. In service they told us everything is ok, but white smoke is still there. Anybody??

Seek out another mechanic. White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Most of the time this is caused by a blown head gasket. A loss of coolant with no apparent leak, a white foamy substance on the underside of the oil fill cap, oil level overfull, and air bubbles escaping from the radiator are other symptoms of a blown gasket or cracked head. Stop driving this vehicle until you have this diagnosed and repaired. A compression test will verify this. Serious engine damage will occur if you indeed have an internal leak so make sure one way or the other.
