Error 2

[dinkydi]

i get that if i start up in the garage the sensors are to close to a wall or some thing, put ur car in the open see if it goes when u start up, also if the sensors are wrong, but doing a default puts all the sensors correct so think you may just be to close, if so that,s normal

Error 2 on start-up in case when sensors are picking-up an obstacle (wall, garage,...) is a bug that has been solved recently. This fix will be available in next firmware update.
