I run Bailey BPV in my Stage 3 S4, as mentioned, I pressure tested etc., valves seemed to pop/hold. Dave suggested they were the problem, so tonight I took them apart.

The piston/o-ring were bone dry...

the spring &amp; inside of the piston head were very well lubricated. ;-P

I used some Amsoil Lithium high temperature grease, and after being a lazy sod &amp; doing this nightmare with my valves on the car (not recommended btw)...if you have man hands, working with that little allen wrench &amp; teeny little bolts just simply is not fun.

Anyhow, after a warm up/15 minute acceleration/speeding blast, I was unable to knock it back into limp mode. I did get a totally flat feeling at one point, but it went away after I switched gears &amp; accelerated (this was at the beginning, so I'm thinking the lube just needed to spread a bit more.

Anyhow, as the week goes on, I'll repost if this didn't fix it, but for now, it appears to have done the trick.

Thanks again DAP.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1723493.phtml">Earlier thread today...</a></li></ul>

I still can't believe you didn't think to grease the valves regularly....

I don't drive it in the winter, and when I started getting it, I found a very loose clamp on the hose running from MAF to Y Pipe.

Once I'd tightened everything up, and pressure tested, I figured it was ok...when it kicked back to limp on Sunday...it was time to start re-checking.

The Bailey valves don't need to be serviced...it says right there on the AWE website. ;-P riiiiiight.

Much easier to take them off the car and do it. Just the two hose clamps and the crimp clamp.

Glad it worked out though.

That is total BS by AWE. I can't believe they spread that BS :/

after fvcking around for 90 minutes on the first one, I pulled off the right one &amp; did it in 30.

While I'm being honest...I'm a complete retard &amp; wasted 10 minutes wondering how I'd get the piston &amp; spring back in without being able to compress it &amp; insert it at the same time, then I thought "hey, it is a vacuum system", clamped the small line on the nipple end, and voila, it stayed compressed.

This is why I don't DIY...no patience &amp; slightly more know how.

Well, now you know for next time.
