I'm a new 535 owner,
I've noticed a higher than normal amount of white smoke in the exhaust - not too thick, but enough for me to take notice, and my coolant was low - which I thought could have been the heater core over time - , but now I'm thinking (fearing) the headgasket. Is there any other reason for white exhaust in normal weather?

Also, peroidically I get a whif of raw fuel, related?

thanks guys.
