I've had my 12C about 5 months now with zero headache.... Today I did a hard acceleration in safe area from 70 to 140. When I let off I immediately noticed a slight burnt smell that was unlike anything i'd smelt before... I also thought maybe I saw smoke in rearview.... Otherwise all was good... When I got out I could hear a fan going in the left scoop i'd never heard before and I briefly noted the smell again, similar to burnt rubber and the stale air inside of a tire... When I came back out 2 hours later I could see lots of drips under the car and tasted one and it was antifreeze. sweet.... I drove car home and about 15 miles in "CLUTCH OVERHEAT" came on and limp mode ensued... Pulled over and waited for everything to cool though water/oil temps were normal... Finally drove home and heard fan and smelled same smell again... Thoughts? Nothing obvious to see looking down into engine bay.
