I had the light come on late yesterday afternoon. I was by an Autozone so I had them pull the code up with whatever scanner they had (it was free). The code said P1475. Any ideas what this is and how to fix it? Is the car ok to drive in the mean time? Thanks.

Don't know. SEARCH for P1475 and you'll find it.

I searched, but it doesn't make any sense to me. Anyone else with ideas?

a vaccum on the tank and evap system to detect leaks. I've never diagnosed an evap system on a turbo car, but naturally aspirated cars use engine vaccum to pull a vaccum on the system to check for leaks,so it makes sense that the s4 would use a vaccum pump. if it were me, i would find the pump, make sure it has 12v+ and if it does replace the pump. if it doesn't have voltage, look for a blown fuse.

Good news! It turned itself off! Thanks for everyone's help. :-)

What do you mean it turns itself off....does it throwing the code mean something?
