E Class Coupe Radio/Ignition fault

[Oxonmb]

Morning All

This morning when i got in the car the radio was off, strange as it comes on with ignition, not this morning.

Press the power button and radio came on, when i got to work about 25 minutes drive i got the message that the command system was going to switch off if i didn't start the car, the car was running.

When i turned the engine off and removed the key the radio was still on, so had to switch it off manually.

Will borrow a meter and get the code later, just wondering if anyone has had this fault?

Thanks in Advance

Well no codes showing and it seems to work now, intermittent? not any stored codes so maybe not a big enough fault to warrant a code?
