so when i hit peak boost my AWD service light comes on. Seems to only really happen in 3rd 4th and 5th gears. and right at peak boost, never before. As soon as you turn the car off and start it again everything goes back to normal. under normal driving conditions it never goes off, but as soon as you get on it once from third gear up bam it comes on. Any gearheads with any thoughts? just to be clear its the a symbol on the screen with 4 tires with the front ones turned to one direction. Manual says it an AWD service light. The only other time Ive seen this light is when she got stuck in some snow, but as soon as she got unstuck all was good. also the warning still goes on with the ASC fully turned off.

 

This happened to me one but it wasn't at peak boost, it was after a clutch install, and it was just the fluid being low. Check the resivour In the trunk and see if it's low. Hope this helps

 

Its your boost level. The system acts up when you hit 30 psi.
