location of knock box and atmospheric pressure sensor
 

I'm still trying to piece together everything I need to get her started. I was looking in my Haynes manual to see if I could identify all of the sensors on my car. I don't see the atmospheric pressure sensor or the knock box in the engine bay, or at least I cant identify them. The Haynes manual makes it look like they are on the passenger side of the firewall. Does anyone have a pic showing them so I know what to look for/buy from the u pick it junk yard?

That is close. Inside of the car. On the side. pull back the carpet and remove the cover over there.

heya,

atmo pressure is on the left hand strut tower if your looking at the engine bay from outside car.

GONG!

The atmospheric pressure sensor is inside the car on the passengers side. Far right and way up. Looks similar to the boost/pressure sensor.

Yep, the S4 knock box and the atmosphere sensor are both in the passengers kick panel area inside the car

Thanks for the quick response. I'll have to check that out on Sunday. the manual wasnt all that clear w/ the drawing. I'll be down there installing the ecu and running the wiring harness anyway.

opps, i'll learn to read properly one of these days
