Hello, I own a 95 ssei. Been getting code 0640 on my actron 9145 (qdm#1 fault). Did a live data check and it showed boost at 100% at idle. Is this normal? I took the boost solenoid off and checked resistance. It came in at 195 ohms. I read where it should be between 500k and 1.5 m. So do I need a new boost solenoid? Thanks!

Sounds like you need a new one. A series one BCS will be hard to find, but a series 2 BCS will work.

Thanks! I read where the series 2 will work if you bend the bracket a little..buying one today!
