Limp Mode after hitting bump in road. Help!

SO I was driving a long on 495 about 70 mph, hit a small bump in the road (nothing crazy) then the car lost all power- limp mode. When I got off the interstate I pulled off to a Mobil to try to trouble shoot and proceeded to unplug the MAF- no change. Next I unplug my tuning box, again no change. Any idea's? Do these cars have an N75 valve? I know my 1996 passat did this once and that fixed it. I've also read about vaccum lines that could be bad or leak? Anyone be more specific on this? Thanks guys!

Check to see if you knocked an intercooler tube off or cracked the intercooler itself. Yes - there's an N75 valve on the A4 Jettas. It's up on the firewall - you'll see a vacuum line run from it down to the turbo.
