From reading threads i think that maybe that turbo seals are going out. I have e90 with 82k with CPO warranty until end of march 2013. I'm planning on making a video of the smoke to show them, tell them i'm losing oil/coolant and putting OEM dps back on. The only thing i'm afraid of is that when i put back the OEM dps (which does not produce smoke) and they say nothing is wrong with it i'm stuck with a diagnostic fee for nothing. Car is running strong and no other problems I can think of.

feedback appreciated! thanks
You're stuck...regardless they will want to see the smoke with stock DP's in their shop. I would install the Stock DP's and take that risk.
