Hi fellow Saab owners. I have a 2008 9-3 Aero SportCombi (2.8L v6) that is displaying some very strange symptoms. Very often it refuses to start - I turn the key and nothing happens, no clicking, not attempt to turn over, etc. - when it does start it starts right up. The CEL is on. Car seems to run fine but the fuel gauge oscillates between showing empty and showing the actual available fuel. After driving for a bit, the ABS, TCS, and SCS lights will come on, I think indicating limp mode? Weirdest of all, once the speedometer and tach both froze simultaneously, with the speedometer showing 25 mph even when I was stopped at a light - sorted itself out next time I started the car. I initially thought it was a bad NSS, but that does not explain the dashboard freezing. I took it to a local mechanic (not a Saab specialist but highly recommended) and he was stumped; said sometimes the computer just refused to communicate with him so he was not able to diagnose the issue. Anyway, there are some other issues with the car so I don't want to sink a lot of time and money into it, but it would be nice to have it starting and running consistently, so I'm wondering if this sounds like something with a potentially easy fix or if I'm most likely looking at replacing the ECU or worse.
