Fault codes

[ambjoinery]

Hi everyone. I've recently scanned my S204 C350cdi 2011, with i carsoft mb v3, showed the following fault code
1. Rear sam. Historic relay 1, circuit 15 has a malfunction the actuator dose not open.
Dose this mean relay 1 needs changing? Everything works OK
Anyone have any suggestions?

If its shown as a historic code and not a current one you can safely erase it.
The fact the car is running OK appears to point nothing needs changing.

If you erase it and it reappears, then there is a fault.

Thanks. When I get time I'll clear codes and rescan.
