Engine light on . fault code p0411. air solenoid stuck shut. show

P0411 Secondary Air Injection System Incorrect Flow Detected
p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong.
But mostly you probably have a broken vacume line somewhere

Code P0411 is showing Secondary Air Flow problem

The P0411 code you are getting with that SAAB is the SECONDARY AIR INJECTION CHECKVALVE 95% of the time. This sometimes will allow condensation to build up in the air lines
that run to the air pump and air filter. Its part of the emmisions BS that they put on these cars. The check valve is costly, its usually about $100 or more depending on where you live I guess but its
much cheaper than $600+ dollars plus labor for a new air pump.

In some uncommon instances this may not be the problem, but this is a known issue with the SAAB Q93 and some other models. Once replaced it should be ok for another 100,000 miles +/-.

Hope this helps as late as I am finding your issue!
