Car Forum / Saab Cars / July 2004Follow-Up: Boost problems got fixed!
I have been posting here about my boost problem ('99 9-3 FPT), which was intermittent in the beginning, but then turned into being temperature related. At the end, I got more or less normal boost when engine was cold, but barely base boost when engine came hot. Problem also appeared sooner on hot days. There were number of steps I took to diagnose the problem, with the help I got from this group, and problem was isolated to be either faulty BPC-valve or it's control. Saab dealer offered to diagnose the problem for $100 (or little over). Well, instead of taking car to dealer I ordered new BPC-valve and installed that. I did that because based on WIS, blowing into C-hose should result air flow out from wastegate connection, and same should happen when blowing into R-hose. I was able to get some air through, but it was hard, and did not actually feel like WIS says 'free air flow'. So, I replaced BPC valve and bang, I got all the boost back right away! It cured the bloody thing! I'm happy, happy, happy !! BR:Z > based on WIS WIS? > WIS? Very Intermittent Symptoms ? (oh - was that a W...) Wicked Intermittent Symptoms, then ?

It is an abbreviation of Workshop Information System, the computer software you see used in the service hall at Saab service. It contains all kinds of service, repair and diagnosing information on Saabs with pictures and everything. Very nice. It is the one that also mechanics at dealer use.

You can actually purchase viewing rights on-line for a day, month, etc via GM as a consumer.

You can also find it for free if you are computer / internet / P2P savvy. Not that I would condone such an activity... -Fred W > > >I'm sorry, I thought all Saab enthusiasts know what WIS is.
