Ivan , do you think it will show a code if the light is not on? If I turn the ignition switch off the light goes away.
I traveled 600+ miles and it came on 2 times.That was my return trip home.It came on 2 times the day before. My boost gauge was also very slow to react and it was taking an extra long time to shift into 6th gear. It seemed sluggish a couple of times when accelerating, but would eventually catch up and run normal.
