What Model year is to New

[flmont]

I guess I mean when you need diagnostic equipment for say doing brake work where you need to reset your anti-lock brake systems Bc you changed pad's and rotors or flushed the system..or set the timing on a engine that needed some repair or general maintenance say changing the timing chains and pad's,..etc.,..Iam sure there is a model year where the Durametric system can't duplicate the porsche equipment the dealer uses to diagnose issue's on the newer car's.
