My SL55 just gives me different faulty indications on the instrument cluster. While driving it gives check coolant level, then it goes off, and then check oil level comes on, later the check oil level goes away, and it gives an error with the ESP, BAS, and ABS.. another problem, the speedometer didn't work for sometime, then it worked fine. A week ago, the car temperature indicated 120.. I turned the car off, then on, it moved back to its regular place, like 90-100 degrees.

The whole car is just running fine. However I'm afraid that this turns sometime to be serious and I ignore it.

What problem would this be?

Instrument Cluster ground connection.

Or your battery needs replacement.

My bet is battery.
