X6 2009 35i white smoke and water from left exhaust tip??

[Ravinggg]

Hey guys

New member here. After owning an E53 for last 2 years I went and bought a 2009 X6 35i TwinTurbo. Very happy with it, however I've been noticing that the left hand side (passenger side in Australia - right hand drive) exhaust tip blows a bit of white smoke when initially starting it up for the first few minutes. Then after a while, the smoke is gone but there is still water in the tip and there is a lot of heat coming out. The driver side exhaust tip however does not have any smoke, no water and no heat coming out (only little bit of warm heat)!

Is this something I should be concerned about? I have 3 months statuary dealer warranty where they have to fix anything that could be wrong. Should I take it back to them or is it just condensation/combustion by-product that I've been gathering from forums online...

Also, I'm planning on installing a JB4 Stage 3 tune... is this a good idea? Is it safe?

Thanks guys
