Thanks Dave, the second Autel looks more my league for now. Only really want it to read faults so I can wither be armed when going to the garage & them not charging me £50 odd for a scan plus so I can delete the codes.
Just to be clear I do not mean delete in some dodgy way. Bought Smart car recently, kept going into neutral, refusing to start, kangarooing, slipping when changing gears etc so feared the worst. Smart specialists all said clutch &/R actuator so £500+. Chap came round diagnosed it for £50, deleted the codes & driven for last week and non came back. He said if battery in a lot of modern cars dies the ECU can have a hissy fit, as this was bought from BCA I suspect they may've had to jump it.
