Evenin guys,

Yeh, so Iv recently got my VCDS lite working with a new lead, been scanning and clearing some old fault codes on the S3. Anyhow, if for example, I choose the Engine module to monitor - I click on the button which says "readiness". Theres 8 different boxes with exhaust heating, oxygen sensor etc etc , and what "state" theyre in ...

I have like 5 green, and 3 on red. Giving me a binary code like 1101101 or something similar. It shows up on data locks 001 and 002 whilst logging too.
Whats this all about ? Does it actually give you any heads up on possible probs with the car ? Im clear of all fault codes at the mo, just a boost fault Im chasing around.

Any help would be appreciated.
