Is their a simple option to clear all error codes?
Not one button that does all, you go into each individual section and then it does a scan of that section.
I had a play today. One thing that caught me out, for the instrument cluster I needed to connect the can 2 adapter. I didnt notice it as I was in a rush and then my instrument lit up with the typical battery failure warnings. I thought during the moment my battery was failing, but I went into the braking and suspension settings and cleared the faults I created.
I then went for a drive thinking my battery was toast but all was actually well. Only later when I had another go at looking at the instrument cluster, did I noticed I needed to have also used the can 2 adapter....After I did that I did not create any more errors and stopping shopping for a new battery.
If you are doing any extended work you may want to keep it on a trickle charger. Particularly if you get into using the write function.
Last comment. On my PC...in the bluetooth section my laptop shows as not connected but actually it works fine. When the blue light on the easy mas changes from a rapid flash to a slow flash you are good to go
