Eco vs Sport mode
has anyone had any other potential maintenance items to chase on that?
thanks

Essentially the same engine in my C320 turns 2600 rpm in exactly the same conditions, barely cracking 31 mpg. I think it's all in the gearing, 5-spd in the W203 vs 7-spd in the W212.

1 - Miles on the air filter, spark plugs ?
2 - Check for codes related to the engine
3 - Reset the tranny, and retrain it?
4 - Coils should trigger codes (not necessarily cluster messages) when they have issues.
Mine has @70K+ miles, spark plugs/air filter/tranny+engine oil @60K, no codes, no leaks around the engine and the mileage is between 22->30MPG with some spirited driving here and there (S when alone, E with company).





.If mileage was my main concern I would buy a diesel car
