When i bought my 9-3 Aero about 6 months ago, it was on base boost. Did a quick test, removed the wastegate hose (from the BPC) and it boosted like crazy (as it should). Tested the BPC with a multimeter, it was showing 0 - ordered a new one, replaced it, boost was back to normal. The new BPC i got was brand new, OEM quality (bosch i think).
A few weeks ago, i started to feel like i don't have too much power - put my obd reader on it, boost wasn't going past 6 psi / 0.4 bar, so back to base boost again. Yesterday, i removed (again) the hose from the wastegate and it boosted like it should, hit fuelcut... So it seems the BPC is dead again.
What could be causing this, is it normal for the BPC to fail like this (less than 1000 km). Could something else kill it?
Or maybe i have a problem somewhere else?
Also, sometimes when i do a WOT pull (or almost WOT) - my charge air pipe pops from the throttle body, happened 3 times so far (about 10-15% of the times i hit it hard). The hose clamp was screwed tight every time, but i find it a bit loose...
