Mercedes-Benz 230e A -92 (w124) "start at -30°c" (my ex-car)

It doesn't sound that it liked that start(yes, one hour with engine heater but it's still quite cold). After start we traveled over 300km without any trouble so I think starting sounds were just "I'm f****ng freezing out there!" -sounds :)
And I'm not sure what's wrong with me cause I had to make that ähh.. sound all the time, maybe freezing too :)
