Re: rotten egg smell????
Have a sniff of your screenwash resovoir; I had a similar smell from my car last summer. I thoo thought it was the catalytic converter, but if I could smell it whilst the car was moving, how was the smell getting into the cabin? Turned out the screenwash in the resovoir had gone "off" (how I don't know...) with the heat, and as a result the water turned stagnant. Not a pleasent smell. A quick (well, 1 hour long to get rid of it!) flush of the tank (stinking out half the street with it...) and all was well. Simple things, eh?
