Mercedes C180 Auto sticks in 2nd gear.

Coolant temp sensor may be sticking in cold position causing rich mixture when warm . That will cause idle issues .

hi check and clean the MS air flow sensor, also the gear box needs a service every 2 years. now the service technician will tell you major gear box problems but it happened to me aswell and it turns out the valves inside the gear box was sticking to the valve body and causing the gears to stay in a specific gear till it reaches the rev limiter and would change. so after i got the oil and filter changed on my box, it still got stuck but dont worry as thats a common problem with a very easy solution, take the car on a long road and really put your foot down, let the engine and gear box temperature rise from hard driving and the valves should release itself from the body of the box and re-lubricate itself not to get stuck again

Sounds like the gearbox filter need replacing,,, very common... drain oil . remove gearbox sump. filter right there,
