Question about 2003 Saab 9-3
Lately I have noticed some white smoke out of the tail pipe on start up. Today the check engine light came on. Suggestions?
Take the car to Autozone, they will read the codes via OBD II for free. Other parts stores may have the same policy ... call first. My VW dealer charges $40 to pull the codes!! I bought a low-end OBD II reader for $50, as the wife and I both have VWs.
White smoke is usually antifreeze, the most frequent cause of this is head gasket blown or cracked head ... big bucks. Hopefully this is not you. Unless the car had a dramatic overheating incident, for most makes of cars, this should not happen until you have over 100K miles, probably closer to 200K.
White smoke could also be break fluid sucked in from power brake booster. If it's brake fluid, it will smell very bad.
On cold days, when the car first starts, white smoke can just be normal condensation in the tailpipe ... if it happens after the car is warmed up ... it's something else.
Check your coolant overflow tank level ... if it's very low or empty ... put water in (don't bother with antifreeze yet in case you are burning it up in the engine).
Good luck, ..ajm

I have had a persistent engine light on and off problem for over a year. Multiple diagnostics, multiple fixes, a few too many $, and most recently replaced a turbo that had gone bad -- BTW, the bad turbo creates white smoke, FYI. Still the engine light is on. My technician seems stymied. All solutions noted here have been explored and addressed. Any other thoughts? The car runs better than fine, and after the investment in repairs, I am reluctant to dump it...any ideas?

Check to see if your coolant is low. Also check to see if your oil is a milky color. Has your car been running hot on the temperature guage? White smoke from the exhaust is usually a sign that you have a blown head gasket. the first three things I mentioned will help to confirm this. Good luck and remember to rate all the solutions that you get. Thanx.
