Boost issue!!! 0 boost!!!

[DSMIKE4Gsexy3]

Hey guys!

Figured id come to the professionals for this one. I have a 93 awd tsi with mods. I had let my car sit outside for about 3 weeks because i had lost my key. Having fouond it yesterday i went outside to start it and go for a victory drive. When i started it it was rough on idle. I let it warm up for about 10 minutes and drove it to the gas station when i realized it felt veryyy sluggish. I hit the gas nothing. I looked over at my boost gauge and it wouldnt boost past 0 psi. I have it set for 18. I could faintly hear the BOV. No wastegate. Checked for shaft play. Minimal. All IC pipng is tight. No holes/cracks. so what is the issue here??? Also no smoke. Vac lines seem up to par.

Check for boost leaks.

When you say minimal shaft play, are you talking in and out? or up and down?

but it was fine before it sat. no boost leaks. would 1 just spring up out of no where?

up and down

Even if you have a boost leak it will still build boost just maybe not as much....if its building 0 boost you either have a split coupler,blown or leaking intercooler,or disconnected ic pipe.....highly doubt it is your turbo. But the hotside of the turbo might be cracked that seems to happen alot.

Check for boost leaks and check to make sure your wastegate didn't happen to just seize up in the open position or become disconnected.

Other than that, does the car feel like it's stuttering or feeling sluggish besides not having boost?

check the ic piping to the throttle body i notice when mine sat awhile alot of crap sat in my TB AND CLOGGED it so it wouldn't open enough and would bog when i pushed the gas
