Just a quickie-with a fully registered and activated version of Vagcom should I be able to clear all DTC's after doing a full auto scan.?

It warns me that I need a "Professional Grade Interface for this function"

Thanks
Pete

Correct, a full Ross-tech interface only (HEX-Can etc). Even My MicroCan has a few limitations and that cost £200

Registering the freeware version with a 3rd party cable gives you Basic settings and some other stuff, but not all.

[Clear All DTCs]
This function is only available when using a HEX Interface (http://www.ross-tech.com/vag-com/interfaces.html#Chart) and is implemented in two ways. On pre-CAN vehicles, VCDS will access each control module and clear DTCs from each one individually. On vehicles using CAN for diagnostics (http://www.ross-tech.com/vag-com/canbus.html), VCDS performs this function without accessing all the control modules individually. If you are not using a HEX Interface then you'll need to go into each module that has faults to clear them individually.

you can't clear all of them via the autoscan in one go. But you can go into each of the fault areas, and clear the DTC there.
