01 Engine, Measuring Blocks invalid group entered (000)

Hello, I'm running VCDS Release 18.2.1. Regarding http://www.ross-tech.com/vcds/tour/m-blocks.php I tried to enter Group 000 (which should support special Labels) but I got the Error:
"000 is not a valid Group, Group must be 3 numeric Digits: 001 - 254"
How can I call Group 0? Was there any undocumented feature change?

Please post Autoscan file, ECU's with Group 000 are very old.

At the moment I dont have access to the controller, but I want to understand how things work.

So if I get the Errormessage "000 is not a valid Group, Group must be 3 numeric Digits: 001 - 254" it means there is no Channel 0 right?

What I can say now is that the labefile was 03G-906-018-BRD.clb, and I have an Audi A4 B7
When I was reading the documentation I got the impression that there has to be that special Group 0. Thats why I was confused.

That's a KWP-2000 and/or CAN engine. No group 000 on those, you have to go way back to EDC15 and KW1281 for measuring block 000 to be implemented in a control module.

Ok thx for explanation
