Good day,

Is there a way to see if anything is 'cooking' DTC wise in say the ECU? Eg. some fault is tripping yet hasn't gone past a pre-set fault frequency to generate a propper DTC? Being able to peak 'inside' for such activity would be neato.

Cheers & Happy Holidays if you're into that sort of thing,
Grant

If curious, below is what happened + a full auto-scan (once a DTC showed up)
==============================================================
Last week my '15 Passat TDI briefly ran like the old old firetruck in the first Disney Cars movie. Small children on their plastic big wheels were passing me on the sidewalk. However by the time I made it through the intersection (and finished thinking... call tow truck, insurance, maybe take morning off work) everything was fine.

Long & short, only after two weeks and a couple tanks of fuel did I finally get a CEL with DTC.

As a general rule, DTCs will show up in native VAG mode (what VCDS does when you run an Auto-Scan) before the show up anywhere else.

But for emissions-related faults, yes, VCDS can show anything that the car considers "pending" by clicking on the [OBD-II] button on the main screen, followed by the [Mode 7 Pending DTCs] button.
