Hi, just got vcds so not fully up to date with how it works but not complete novice on dignostic equipment. I have access to 2 different diagnostic computers my mate owns. Delphi and dec scan. Both wont access my ecu! So thought id try vcds. I can manage to read and clear fault codes. But when it gets to live data it seems a little bare there only seems to be few basics available. And trying to access certain parts it wont communicate is this normal on BKN or is my ecu got a problem/partly locked?
