So Ive had vcds for a while now, from NHN.

So far all I really used it for is codes, and live data.

Now I've been asked by a friend to do 2 things.

Turn off auto locking.
Reset long life service light.

It's a 07 A4 Sline, not sure on the chassis code, but have vin if needed.

Is there a tutorial anywhere about coding (on phone so search is limited)

Also, while I'm here, I was reading live data on a Passant, 55 diesel with running problems. But couldn't find fuel pressure or target pressure on the list. Found injection volumes, duration etc but no pressure?
