After running the car and turning it off, i hear a pssssss sound like air leaking somewhere. It coming from the a/c lines near the battery. Just recently i have gotten a CEl for p1136 for ai/fuel metering. is there a vacuum line around there? Im not exactly sure which lines to check fo tthe leak. Er.........

 

yep thast your ac. the noise it not whats causing the cel. all our cars do this. b5s atleast

 

What year/model is the car? Mine was in the shop today, they said my 98.5 2.8 had an outstanding recall for a vacuum line, fixed! Thanks Audi!

 

mines is a 99.5 btw can anyone show me where my vacuum lines are?

 

Assuming you also have a 2.8. The vacuum lines run all over the place. The vacuum lines that are replaced for the recall are above the throttle body near the back of the engin. They connect the combi valves on the back of the heads to the control solenoid on top of the motor.

 

i have the 1.8t
