As I'm sure we all know, the original T5 BPC valve for the 9000 has always been a fragile and expensive part. Eeuroparts offers a kit to replace a failed BPC valve with the newer, more reliable, and less expensive T7 part: https://www.eeuroparts.com/Parts/52650/T5-BPC-Update-Kit-T7-Valve-101K10078/ This kit is included in the Eeuroparts "Parts for Life" program (limited lifetime warranty).
A quick word on Eeuroparts, I've been ordering from there for so long I can't even remember when I started. (It was back when the company was in the hands of the original owner. A really great guy, may he rest in peace.) However I had not ordered for a little while and things have changed. No more free shipping. No more SAABNET 5% discount. Instead they have a "Loyalty Program" where you get a percentage back on your purchases. Signing up gives you an initial $10 credit which covered shipping the BPC upgrade kit. I received a $5 credit for purchase of the kit.
(Correction - on ordering a second kit for my other 9000, free shipping is being offered. Must have missed it on the previous order.)
The kit comes with a T7 valve, a modified ECM (or you can send yours in to be modified), and an adapter cable. Cost is about $150, plus $125 core deposit if you don't ship your own ECM to them for the required mods. I elected to go the core deposit route so the car could be driven while waiting for the parts. I purchased the kit to install in my 1995 CSE and it took about a week or so to ship.
Since the ECM is being modified one could elect to upgrade to Stage 1 tune at minimal additional cost. I did not do that because my 9000 has an automatic transmission. The factory had to detune even the stock programming for the automatic trans so I decided to err on the side of longer transmission life, particularly since Erikkson Industries no longer provides support for these transmissions and just about nobody in the U.S. does at this point.
The kit arrived in a medium-sized Eeuroparts box:
Opening up, we find... packing pillows galore!
So what's actually inside? We find the modified ECM, clearly labeled for future reference, a T7 BPC valve in a bag labeled "Genuine Saab", and an adapter cable.
The T7 valve is the real McCoy, not a knockoff.
Installation is straightforward and took all of about 20 minutes and that was with taking some time for photos. First order of business is to disconnect the battery since we'll be dealing with replacing the ECM.
Next the aquarium cover is removed, exposing the ECM on the left-hand side. (I don't know if that's the same in right-hand-drive models, never seen one.) Removal is very simple since the unit just slides into place into a bracket. There are two tabs that release it. Electrical connections are a ground strap bolted to an ear on the side, and a big connector on the bottom that is not visible until the ECM is removed.
The big connector on the bottom looks kind of intimidating but it comes off easily by pulling a lever.
Installation, as the saying goes, is the reverse of disassembly. The only issue I ran into, very minor, is that the ear the ground strap attaches to was not threaded like on the original ECM. Some appropriate hardware quickly took care of that.
So with the modified ECM installed we turn our attention to the reason for all of this, the infamous T5 BPC valve.
The Eeuroparts kit is very complete but leaves one thing to the imagination - mounting the new T7 valve. For now I elected to wire-tie the valve to the metal intake pipe, and tie the adapter connector down to the old mount to keep it from flopping around. (It would probably be better to fabricate a proper mount but this should suffice for now.) Hose connections are easy since the valve and hoses are marked.
Put the aquarium cover back into place, reattach the battery, and that's all there is to it. The car fired right up and on a quick road test proved to be noticeably more responsive than when it was stuck in base boost. (Unfortunately the boost gauge in the dash is currently disconnected due to a bad hose so this is strictly a seat-of-pants evaluation.)
I'd say this kit is well worth it. In the near future I'll be ordering another one for my '97 CSE which also has a bad BPC valve.
