White Smoke from Under Hood on SLK32
The other day I just finished a 20 mile commute to the office, got off the highway, and came to a red light. I then noticed my vents (on EC mode as it was cold out) were spitting out a burning smell. Not a coolant-sweet smell as most people describe. Then I noticed a bunch of white smoke coming out of the driver's side hood, between fender and hood, up next to the windshield.
The smoke stopped after about 7 seconds and both it and the smell went away (I was still stopped at the light).
On the ride home, it did not happen.
I opened up the hood when I pulled into the office (it was a block away) and looked where it was coming from. I couldn't tell if there was any leaking.
Things in that general area are my power steering reservoir, some O2 sensors.
I'm pretty sure it's a fluid leak that came out and hit the hot something-rather below and burned off, but my concern is what fluid and where it's coming from.
I'm pretty sure it wasn't coolant, as it was a very distinct burnt smell. So it could be engine oil, power steering fluid?
Any ideas? Should I take it to my mechanic?
