So since I bought my 8 3 months ago I have had an issue with the TPMS light being on all the time, I check my pressure regularly but it depends so much on the outside air temp, it comes on everyday. This was tolerable, but within the last week I am having the exact same issues with my oil pressure light. It only comes on when it is cold, or hot. I dont understand! I checked my oil pressure and everything is fine. Should I take it in to see if it is a code or something? Could it be my CPU?

All suggestions are worth looking into! Thank for the help.

 

Those 2 things have nothing to do with CEL...
Sounds like you don't have TPMS on your wheels, or they have gone bad.
Does the oil light goes away after you change oil? Check for any leak.
