Hello to the group!
Now with the warm weather I am driving my 1985 900 Turbo 16 with the roof open.. This has the effect of nasty fumes entering the cabin when I release the accelerator... The car uses no oil and runs very well and all the hoses seem to be connected properly (195,000 miles). Any ideas??
Thanks in advance!! E.
That's odd; it should be extracting air out, rather than pushing air in. Do you have the fans turned off when the roof is open?
What do the fumes smell like? Exhaust, oil burning, or ??? Are they coming in the roof, or is it really from the vents?
i bet it's just from the exhaust...in the clasing 900's i believe the exhaust pipe comes straight out the back, rahter than curving to the side (at least mine does). when driving, you create a small vacuum that causes wind to come from the back of the car which is enough to pull exhaust from the pipe. my saab isn't a convertible, so i don't know if this problem happens on saabs, but on my old jeep, just changing the exhaust pipe to come out of the side fixed everything.
the reason you may notice the smell more when you take your foot off the accelerator is kinda wierd. maybe there's unburt fuel or something coming out, but don't know.

I have a 93 9000 not a 900 but I had a similar problem with gas fumes every time I opened the sun roof. The problem went away after I replaced the gas cap.
Hope this is a help. Peter
