Ok, I'm sure my boost problem is temperature related ( It is '99 9-3 FPT, trionic 5). When engine becomes hot I loose boost. Instead of reaching border between yellow/red zones, boost gauge gets just one quarter on yellow side, mid-yellow at maximum, and you definitely feel the difference :( This happens faster in hot days. And it happens always if you drive the car hot. I have found that when I lack boost, disconnecting hose that goes from BPC-valve to waste gate cures the problem and I get all the boost back, and more. Gauge jumps on red zone!. This makes me think it is not a vacuum leak or turbo problem, but either BPC-valve or boost control (or one of the sensors) must be faulty. I thought I could buy BPC-valve and see if it cures the problem. However, that is almost $300 at dealer and $200 at eeuroparts. Too much for me, if it does not cure the problem. I went to dealer and they said they probably could diagonose the problem in about an hour, which equals to one hundred dollars. Now I do not know what might be the wise thing to do. Should I hand $100 for dealer and know for sure, or spend $200 at www.eeuroparts.com and try new BPC-valve. How likely is it that BPC-valve is broken? Does that happen often? My car has now 73kmiles on clock. BR:Z
