So my 900 had the TEVES II abs system. The abs light is on all the time and the fluid light flashes if I hit the brakes fast, but I can keep it off if I go easy. I thought it was likely the accumulator, but brake pressure is good and I don’t think the pump is continually running like it is trying to build pressure in the accumulator. If I turn the key to the on but not run position, and hit the brake pedal I get a momentary whir but it goes off even if I keep my foot on the brake. Not sure if I should be looking at a new accumulator, or looking at something else like a loose connection or a wheel sensor. Any ideas?

So I saw that the pump was going on, so I went ahead and got a new accumulator. I have seen references to having to replace the metering valve from the old accumulator onto the new one, but I can't find any photos online, so I am not sure what I am looking for when I remove the old part. I did not get the Delco one, but one that should be SAAB specific from SPEED Manufacturing. It is listed as:
Brake
Accumulator
for Lincoln
Mark VII,
T-Bird
Supercoupe,
Mercury
Cougar, SAAB,
and Jaguar
Teves
Hydraulic
Brake Booster

I decided to replace it because the pump is running when I hit the brakes, and all of the symptoms are there. I still thought the pump would run longer than it does, but after looking at it again, doing more reading, and reading that pulling codes can be hard without the proper equipment (according to the bentley manual), though I did find this, and will llook into it, accumulator aside http://townsendimports.com/Web/brake_folder/900abscodessbpg1.htmI. I decided it was worth while since they all go eventually. Since Accumulators are getting hard to find at a reasonable price now that the Delco version is discontinued, it made sense to get one while while I can still find them and not pay 400 dollars. I might start accumulating other harder to find parts as well, just in case....though I see your concern, I don't want to waste money on parts I don't need.

Man, be cautious with no-name Chinese parts. I'm not saying it's a for-sure problem, but, really, be careful. You're not only talking about the things that stop your car but also a thing that stores a **** ton of pressure. A failure there wouldn't be great. In my (and I think many peoples') experience, old used OE parts are better than brand-new no-name parts. Diagnosing problems is an awful lot easier when you can trust the components!

The Factory Manual will tell you how to retrieve flashing light codes from ABS with a piece of wire to jump the test socket. You can check wheel sensors and pressure switches with a voltmeter.
The Bentley manual will mislead you with partial generalized information.
If you want to educate yourself, read the real manual, it's even cheaper than a generic manual...

Thanks for the tip, Jim. I will check out the guide on SAAB Central.

Hi, so I received my new accumulator. It’s a little bigger than the old one, but it fits. Only issue is the metering valve is too loose to stay put in the new accumulator. It falls out. I don’t know if it can do damage to the pump if it were to dislodge while in operation. I have also read some older posts here that say that the valve is not strictly necessary. Anyone have any perspective on either of these two issues?

Just an update, I installed the new accumulator and things are better but not perfect. Before new acculumator, the pump ran every time I hit the brakes, and the fluid lamp went on as well, and I maybe had three pumps of the pedal with the car off before it got hard. Now I get the pump on after about 5-6 times I hit the brakes, the fluid light goes on when the pump goes on (Normally when I start driving after braking) then goes off after a bit. And I hit the brakes with the car off 20 times, and still did not get a hard petal. The accumulator is new, USA made by HYDAC. My next step is to try to pull the codes, see what is up.

Referring to questions about the Metering Valve: In my '90 SPG I've installed several Accumulators (testing them) over time. I've never paid any attention to that valve - don't even know what it looks like. My ABS performs perfectly fine despite my best efforts! Vern

Thanks. I might remove the metering valve, see if the pump runs a bit less. I did figure out the brake fluid light: The accumulator took just enough fluid from the reservoir for it to be just at the fill line. Topped it off, haven't gotten the light since. ABS light is still on, but that could be a wheel sensor, or a hundred other things...
