just got odb 11 still learning-on first use found four fault codes thought they maybe faults from previous owner so tried to delete pressed and held red button ,message at bottom of screen saying "problem deleting fault codes" or something like that? also way have some fault codes got a red bar on the left side and some have green-one last question how long should it take to connect  mine seems to take an age about five minutes-sorry for asking so many questions thought I would get them all out the way.

Try updating the obd11 app and have Bluetooth switched on 1st. 

ok thanks for that will give it a go.
