I just bought a 2001 9-5 sedan with 19,000 miles. At the dealership, a puff of white smoke came out of the exhaust on one of the start ups and the salesman explained it away with detailed talk of the turbo, "it's a saab thing", it only happens when the ignition is in ON for a bit before you start it, etc. I test drove it a couple times on different days and it didn't happen at each start up. So I buy it (both the story and the car) and of course a huge puff of white smoke envelopes the car on my second start up (wasn't in the ON position for any length of time). I'm thinking exhaust should always be invisible and have been told it could be the turbo needing to be replaced. Is this a Saab thing?? Anyone else every heard of this? (we're talking huge puff of smoke) Thanks.
