I would say it's worth a try. I guess the DiCE connection could run your battery down since your engine won't be running (and battery won't be charging) while you check for codes. You could hook a battery charger up while using VIDA or have another vehicle running with jumper cables attached to your car's battery.
If you're getting a metallic noise when cranking the engine, then something may be interfering. You could try manually turning the engine crank slowly with a socket and extension to see if you can determine the cause or where the noise is coming from. Re-check your work as much as possible to see if something was left unattached or put in the wrong place, etc...
