randomly while driving my asc will shut off and say it needs servicing, i shut the car off and turn it back on and the problem goes away. however, lately we have had a couple feet of snow so i switch it to "SNOW" and again randomly it ASC will shut off and tell me to service it... restart the car and its fine..

anyone know what i need to service or what the deal might be???

 

Are you sure that it's shutting off? The display changes whenever the system kicks in above a certain point. Maybe you're just seeing the "you are skidding" display.

 

Or as i like to call it "the drift light"

 

Paranormal activity?spoooooooky

 

lol... "drift light"... im using this fron now on

 

no the ASC off light comes on and caution triangle comes up until i clear it.. ?

 

haha yeah man "drift light" i like it

 

I've had the same problem. Mine happens rarely, I'll drive it normally, and it'll shut off my ASC by itself saying that it needs servicing. I did my fluids 20k miles ago. Could be due for one soon I guess?

 

Sounds like pump issue... possibly air in the hydraulic line? Try getting it flushed at the dealer for starters...

 

asc is nothing to do with the pump, sounds like overboost to me
