Somebody can help me？ I have a Audi A4-2004, 1.8T. recently found that something was wrong with the the engine, there was a little noise when I was driving. So I wanna buy a diagnosis tool to check, and I choose the Autocom CDP Pro CARS (Compact Diagnostic Partner ) CARS, http://www.autoobd.fr/autocom-cdp-pro-compact-diagnostic-partner-pro_p1120.html. Is that can be worked? Who can tell me.
