Sorry guys,

I've been reading almost every relating cold starts and CCV valve issues. I have rough start as well, followed by Rough running when in gear on cold! Then SES Light turnes on and some unburn fuel smell comes out of the exhaust. Really noticable. However the SES light goes out after 10-15miles of driving. Any Ideas? Could it be notorious CCV? (Also I get O2 sensor messages) I have them orderd. As for Cat itself: Indy has told me that they are ok.

Whoops sorry, I forgot. 00 X5 4.4l m62
