Visible exhaust
5

Asked by BCHEETBMW Jul 01, 2015 at 07:11 PM about the 2008 BMW 7 Series 750Li RWD

Question type: Maintenance & Repair

I have a 2008 BMW 750Li with 88,000 miles.  Other than the common minor / slow coolant leak (yet to fix) it has been a fabulous car.

Two days ago I noticed after a restart with the engine still warm, it was burning visible, white colored exhaust.

I had the oil changed and it still did the same today.  I typically use shell V- power gas.

Any advice to treat this?  Fuel treatment additive perhaps?

Thanks,

Brian

Are you sure the white colored exhaust smoke is not coolant?
