Error 47 und 49

What is the meaning of error code 47 and 49?

I see error 049, too. What does this mean? The SBV is running as normal.

I have that too since the update. It flickers between 047 and 049..

Bei mir die gleichen Fehlermeldungen. Immer abwechselnd 047 und 049.

I have error 049 as well. What does it indicate?
