When I run the output tests under Engine module of vag-com, along with the clicking for each component that you are supposed to hear, I hear a sound like air leaking.

Can someone please run an output test on their car and report if they the sound of air escaping/just running through pipes/hoses is present.

I have run it many times before, but cannot remember what it sounds like other than the clicking sounds from each component and can find no other reports on the forums or elsewhere of what it is supposed to sound like.

I have previously had two fuel injectors leaking both air and fuel. To remedy, I replaced both o-rings on all fuel injectors. I am beginning to suspect that there is a greater problem with at least one of the fuel injectors that were previously leaking over and above simply old/worn o-rings.

I continue to get codes 17535 and 17537 relating to long fuel trims being too rich on both banks.

So I think that the air noise that I hear is one or both of the fuel injectors continuing to leak air necessitating that I replace one or both of them, unless that noise is normal during the output tests.

Thanks in advance!
