The question, I always thought when VCDS "talks VAG" it only talks to the CAN Gateway, which itself talks to whatever module. So if I can't communicate with the CAN Gateway because of a faulty connection on the diag port, why can I talk to the other modules? Or does VCDS use K line?
Briefly, my EML came on (and won't go off). Scanned ECU 1 - some error with the camshaft range from 4 months and 400 miles ago (about right with my mileage) - MIL confirmed on. Only 2 occurrences.
Weird... nothing current? And I never noticed the MIL on 4 months ago. Maybe it self cleared and I never looked down or something.
Checked ECU 2 - no errors. Fine, let's autoscan. "Not Supported by the gateway". Even weirder. Tried opening 19 - CAN Gateway and no response from controller. Every module I tried except for this works if opened directly. BCM, engine, ABS... just the gateway.

As per usual, searching comes up with solid advice from Uwe - check the CAN spade connectors on the port. Yeah, pin 6 looks really odd. Common on RHD vehicles.

VCDS is working fine on another Audi of this vintage. CAN Gateway all happy and accessible. Over the weekend I'll troubleshoot it further, I've got enough bits lying around to fabricate some temporary wiring or may even repin the port. But it's also strange how I have an EML with no (active) stored code.
