Welcome to the forum! :)

I Googled your fault, and got this:
C1121 AIRmatic: fault in component B24/3 (acceler. sensor)

Unfortunately, can't tell ya much more as that isn't my area of expertise...Got Apple problems? Now you're talking! :D

The reference for a Air-Matic fault is invalid for a smart, as they do not use Air-matic struts. Most manufacturers use C1121 to refer to a left front wheel speed sensor fault. I do not know whether that is the case with smart but using a proper scan tool should provide a code description.

Is that what the "(acceler. sensor)" bit means?

I just quickly Googled the fault. Holy smokes there's a ton of different codes a car can store!

Ah, interesting!

Note to self: MB fault codes =/= smart fault codes.
