Gota codeP0171(lean bank 1)I used the search earlier and did some research. I cleaned my MAF at work today and inspected all my hoses from the posts I checked all the fore-mentioned.. Could my new diverter valve be the cause? Im trying to figure it out but working at a Chevy dealership does not prove to be much help on these Audis

 

If it were the MAF it would probably be lean on BOTH banks, you probably have a vaccum leak somewhere on the passenger's side, check all your vac lines.

 

Hey auditech79, he has a 1.8T - it's a one-bank engine.
Yeff24, clear the codes and see if it pops up again. Has it been running rough lately? The DV might be the cause if one of the lines came off...did you replace the original vacuum line to the DV, or did you re-use the old original one?

 

Would have helped if he posted that [:@][&o]

 

Yeah, I had to go into his 3previous posts tolook forwhat engine he had. I figured it would be easier that way than asking him and waiting for a reply...

 

Ya thats my bad it is a 1.8t I didnt have much time to type my question because I was at work so I havent been able to check anything until I got home...it hadnt been running rough at all....but I was able to find out what was wrong the vaccum line that attaches on the right side of the motor which I would believe be the intake manifold the hose was attached and secure but on the bottom under the manifold the hose was ripped and just hanging on so we got some new hose and wired it up thanks alot for your guys help...Im new the forum thing so I'm learning as I go that I need to put all the info in.. Thanks alot for your guys info and suggestions
