Mercedes-Benz 230e A -92 (w124) “cold start -30°c“

It doesn’t sound that it liked that cold start(yes, one hour with engine heater but it’s still quite cold) so I hope I don’t have to do that too often. 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 :)
