I've just got this 406 2.0 GLX estate 1998 100k on the clock. When I picked it up on Wednesday it was fine but since Sunday there's a dreadful eggy type smell which must be from the cat I suppose. This happens even after 40 miles down the motorway, to the extent that I have to put the air onto recirculate when I'm sitting in a traffic jam. I did fill up Wednesday evening and again on Sunday at the local Sainsburys but their pumps say ultra low sulphur petrol. Could it be the lambda sensor or O2 sensor? GSF don't seem to list these in their online catalogue and an enquiry via their contact page brings a response asking for my chassis number.

I have read that the air conditioning can smell (although I have no idea what it smells like) and that there is a can of something or other that you can get in Halfords to treat it.
But it definitely isn't the air con. It comes from outside the car and increases when you rev the engine.
It must have had the Cat replaced recently - they sometimes smell a bit when they're new. Providing your emissions are OK, nothing is broken ! You'll just have to be patient until it goes away.
Thanks. Does that eggsplain why it didn't smell when I got it on Wednesday last week? A colleague has also commented that the end of the exhaust is at the back of the car so why is the smell getting in?
Because of the backdraft. All vehicles produce a backdraft, if you drive am estate car with the back door open, the exhaust fumes will be dragged into the car.

But not when stationary which is when I notice the smell. I have seen elsewhere that there are non-return flaps somewhere at the back of the car to vent the passenger compartment. Any idea where?
If you pull out the boot trim on the right hand side, you'll find the vent flap in the inner wing just in front of the lighting cluster. Martin
