Could you please give me more information on the replacement hose? What type of hose is it? Where is it located exactly? Just trying to pin point the hose so that I could try it out on my car with the same symptom. Thanks so much.

 

Sorry for the late response put the hoses are under the engine cover towards the top part of the engine. To find the hose with the leak you should try to turn the car and listen for a hissing sound. Most likely the hose is rotten and is falling apart so it is best to change them all. I also changed a Evap part but i am not sure what it is acutally called the part is like 140$ and it is under a cover on the passenger side of under the hood.

 

Thank you very much for the reply. Would appreciate it if you could find out the name of the replaced Evap part! By turning the car to check for the hissing sound, did you mean to turn the steering wheel to the left and right while the car is in park? Thanks again.

 

you actually do not have to turn the steering wheel at all. just listen for a hissing sound and start moving the hoses once you here an interruption in the sound you will find it. I will let you know as soon as i find the part name

 

Thank you very much for the reply and for looking into the part name. The engine has so many EVAP parts to narrow down.

 

I have a hole in one of my hoses under the hood as well. I put some tape around it for now but I don't know were I could buy this hose. Its just under the Pressure Control Valve or Pressure Limiting Valve for those familiar with it. Its on the top right driver side under the cover. Kinda looks like a DV but isn't. As I said above I have P1136 & P1138. Would a hissing/air leak cause this?

 

definitely! that is most likely the problem! you can purchase the hose at any auto part store but i suggest to buy it from audi and change it yourself. I saw my mechanic change it and it was not hard at all make sure you measure the hoses right and change them as you go! dont take them off at the sam time or else you will probalbly be screwed! Most likely they are all going to rip eventually so just change them all. After you change them drive for about a tanks worth of gas and then vag-com the car and make sure the codes are gone.
