if coming from exhaust , then no will have nothing to do

light smoke on twin turbo is normal, would say it does it more on take off or after sitting at a light ?

any check engine light on , any warning lights ?

Are you looking for the most possible causes or you are repairing it yourself .

Please Let Me Know

Thank You

No check engine light. Smoke comes out when car is parked on idle.

what is mileage on it ? and do you have oil low at oil change do you have to add between intervals ?

Turbo oil seals or valve stem seals could be the issue here ?

did the smoke happened suddenly or gradually git worse ?

does it make a bug puff of white smoke and then after u get on it goes away ?

it want do it each time ,have to sit at idle few minutes correct ?

69k miles. Normal oil level but I do have to add between oil change intervals. Smoke happened suddenly. One time occurrence it was a lot of white smoke, but afterward only clear light smoke occurs every now and than. Yes, one time it made a big puff and went away when we drove off.

i m going to say the turbo seals are heating up swelling and allowing oil , i would not worry about from all u describing

when they sit for a while they will do that and if u drive them slow and do not get it on every once a while it will do that

take to a ride down the highway let it go thru it shifting and get up to 70 80 speed ,do that once a month will be my advice

until it gets worse or does it more
