9-5 1.9 TiD rough idle when cold
Ours has done 58000 miles and is a 2007 model. When we got it, it wanted a new egr valve and i think it has been done because the dealer was a bit strange at first and not wanting to know about it, but since it went in acceleration has been fine and no power loss at all. However, when the engine is cold say when you first start it in the morning, it doesn't tick over properly- it isn't smooth, and there is a slight hissing noise as well. However, when the car warms up to normal temperature, both these problems disappear. Any ideas?
