During the summer I threw both lights when pushing real hard one day.
Both went out soon afterwards, and dealer checked codes and charged me $120 since code was thrown due to overboost.
That was the only time I triggered the SES.

Now that its cold out, about 40F, w/o even pushing that hard, i threw the light. Next day same thing. Probably at 5500-5700rpm.

Could the cold air be doing this?
Any concerns?

Thanks!

 

Some of what you are seeing is the fuel mixture causing the SES. ( this car too - it's gone now )

Any concerns? NO, not here.

 

Got my overboost permanent DSC light/code yesterday.. woohoo!! got a huge smile on my face.. usually it only happened at redline in 4th but with the weather down here in miami it was rare cause of all the heat.. yesterday it was in the low 50's and sure enough, overboost w00t.. lol

to answer your question. no concerns here, well actually just 1, with the colder weather its MUCH easier to break my tires loose... and yes the cold air is a factor... don't worry, just enjoy the cold weather while it lasts..
