Yea it really looks like a big pain! wish I would've known you had one earlier! But than again glad I got the right one. But yes I'll have to do that! Just by sucking up half a can of sea foam threw the vacuum everything seems to be running a lot better might just do the other half.. :P

 

my throttle body had sludge in it. nasty. couldn't even see metal, the clean helped, this was all after full sea foam it was still that dirty. it can only help

 

So I've just noticed something else today picking my sister up. Does this happen on all the audis or what? Or is their even an explanation for it?? Basically cars warmed up and everything just cruising and I was peeking at like 9psi or even 10psi usually goes down a bit and stays steady at 7psi. After awhile I've noticd it goes down to 4 psi and just won't pass that. Anyone have any explainations?
