Suggestion
Is it a smell of fuel, the turbos run extremely rich on startup, one of the reasons that you should not let it idle when cold which could lead to bore washing and if you use a hight grade fuel the fuel will smell quite a lot in an enclosed space.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Recently I've noticed that the car is extremely stinky with fumes whenever I start it from cold. It is really quite bad - you don't want to be standing near it for the first 10 seconds after it starts, it's that bad to breathe.
Any ideas on why this would be? It didn't always used to be like this.
cats don't last forever; you might try what they used to call an Italian tune up, but in this case, the idea is to get the cats nice and hot to activate them and burn off any residues - not always easy in the winter, I know

It's exactly how you describe but it hasn't done this forever, only in the last few months. I'm just wondering what might have changed. It lives outside so no worries about enclosed spaces.
Leaking fuel rails due rust? Does it also smell when you park up after a drive?
My C2 just had this problem, unsure if a Turbo would have this issue as a different design.
Edit: This would strongly smell of fuel not burnt fuel.
If it's not burnt eggs, but unburnt fuel, it might be running rich on a cold wintry start. Is there a lot of black crap coming out of the exhaust?
You could try parking in a warm garage overnight and trying a cold start .... diagnosis over the internet is never straightforward.
Okay thanks guys. Sounds like all is well and i just need to hold my breath for a bit. Car runs well, no knocks from the exhuast etc, so I'll just keep an eye on it. Appreciate the replies.
