So I was leaving work today and hit a very shallow pot hole, it wasn't big enough to bottom out but more or less just cause a little thump.. Well then I went to accelerate and I gave it a little throttle and now I have a drastic power loss that wasn't there prior to pulling in my work parking lot before hitting the little pot hole.. I have no codes, no rough idles, etc and the car runs fine until I try to go into boost and it's just not there at all, yet I can hear the turbos spooling and it kind of sounds like I now have a BOV when I let off the gas because I can hear a swoosh of air when I try to get it to go into boost.. I'm thinking a coupler or hose came off somewhere, but just checking to see if it was a vacuum line I'd get a low boost code or something right..??

I felt that elbow on the charge pipe that curved and goes to the intercooler and it was very hot, but also very flimsy, however I didn't really notice any breaks in it.. The first thing I did was inspect the charge pipe but it wasn't broken at the connection near the throttle body, so I imagine it's a hose connection somewhere.. I'm going to check it out tomorrow but just figured I'd ask about the vacuum line thing too so I know which route I should head in diagnosing if all boost connections check out ok.. Stock CP and DV's...

Thanks..!

What Intercooler are you using? If it's stock, pull your splash shields and inspect the plastic end tanks. My girlfriend hit a pot hole and cracked hers. It doesn't take much to crack them.

Yeah I'm going to do it in the morning, I hope that's all it was..

Yes stock intercooler and stock intercooler piping btw..

It's a good excuse to upgrade, if broken.

I came off a speed bump pretty hard once and the front nose bottomed out and it ended up separating my driver side fmic pipe. Another time, I came off a speed bump hard again and bent my mid pipe right where it bolts up to the downpipe. Try checking those.

Boost leak, a nice sized one

Damn bro, that's some serious bottoming out. Have you thought about getting a lift kit
