The Mercedes SBC system is notorious for its issues. One error which I came around at my cheap Mercedes e class, is the Service Brake! Visit Workshop! error at my dash. This indicates a problem with the SBC pump. In case it is caused by error c249f, it just indicates a threshold has been reached. This doesn't say anything about the SBC pump itsself, it indicates that Mercedes find it nescecary to replace the SBC pump to prevent issues.
In this video I'll show you how to reset it with a 35 USD tool from Amazon. It worked for me, however, do be aware that Mercedes considers it unsafe to use the brakes after the threshold has been reached.
The tool which I use on Amazon: amzn.to/3lZMle1
