f82 m4 random white smoke

[undergl]

Hi all, my bmw randomly white smoke appears through the exhaust. Generally at low speed.
also, you have to fill oil every so often so I suspect that white smoke is oil.
What could be the problem that he is throwing oil through the exhaust?
Any known failure to make these symptoms appear?

I've got the same issue right now...

Do you have down pipes?

It's most likely a failing/failed journal bearing on the turbo. Oil bypasses the seals and hits the super hot turbo components producing the white smoke.

Only happen's when the car is hot correct?

Yes, only when the car is hot and at slow revolution.

For example, the other day after 100km arrive at the destination, being already in town after stopping the car and start again began to do so, throw white smoke for about 2 minutes and stop again.
Of course, the oil consumption is remarkable and I think more and more.

I'm pretty sure you have a turbo seal leak my friend. Same thing happens to me and sometimes when you stop and go, you'll see smoke everywhere. I'm just about to get my turbos swapped out for Pure Turbo's because of this issue. I have downpipes as well and its not from those because I had the DP on for at least 6 months before my turbo's starting to give out.
