Then I think you need Mercedes diagnostics probably if there is nothing obvious.

 

Look about for a private Smart specialist if you can or Mercedes specialist if you can't find a Smart one.

 

Do not take it to a Mercedes garage, they will have your shirt off your back.

check electrical circuit of fluid level sensor...make sure float is working if it uses a float system

 

if thats not a problem then id suggest accessing a scantool that can go into the various body control and abs modules to read actual live data of switches and sensors to narrow it down
