Ok this past Saturday i was changing my oil where i was parking it was a small incline with grass rear tires spun on the grass for a sec no biggie. after that while driving my car (i always turn off my traction control off) beside the traction light being "off" a second light above it that looks the same except no "off" under it came on. i read up on it and its the stability control light but there is no effect on the driving what so ever it stays on however sometimes it will go away and my traction turns on by itself i then turn it off again and it doesnt come back on could the sensor be dirty after spinning in the grass?
