Eric Flowers, full time Saab technician, make this great video that simply explains the SAAB LIMP mode.

Limp mode is one of the most common issues Saab owners encounter, so He made a YouTube video explaining Saab limp mode in as much detail as possible. He tried not to make the video too technical, and to stay within layman terms.
