2001 SAAB 9-3 repair Question

Hello, im assuming when you say "flashing on" that you mean intermittently appearing on dash, this is almost certainly fluid levels, firstly check oil via dipstick ensure level is within permissable levels, then check brake fluid(most likely to be this) look at the bottle its clear(ish)there is a mark on it, max and min ensure its at the max mark, check coolant via expansion bottle, check power steering fluid, this will amost certainly solve your problem
