I just started driving my 2006 9-5 to work recently and there is some white smoke that looks like it's coming from near the turbo or around that area. Only happens at idle though and it's not alot it only lasts maybe a second or two. The smoke comes from the engine bay and not the exhaust and that's what confuses me because I can't find any information online about it. Anyone know what could cause this???
I am a new Saab owner, so it's better to wait for the experts to weigh in, but here are a couple of thoughts in case it gives you any ideas:
1) If it happens on idle and disappears after a while, it could be an oil leak that is getting on the exhaust manifold. Of course, the oil just burns off on the hot manifold because the oil leak isn't that
bad (check the regular suspects, valve cover gasket etc.)
2) Similar thing could happen with a coolant leak too, although this is less likely.
As you can tell, my going theory is a fluid leak on a hot surface. If possible (maybe on a weekend?) take a video upon startup / during idle, that might help some of the other folks here help you.
